My perfect ring
I knew I wanted a rose gold ring in a vintage-inspired setting, and the Reina Halo is absolute perfection! I purchased my ring entirely online (not from a showroom) and I got mine set with a 7mm cushion-cut premium moissanite. While thin and dainty, the pavé band is definitely more durable than I thought it would be. It is so comfortable to wear, and while the gem sits a little higher than I would prefer, I'm sure this is to comfortably accommodate my future wedding band. Overall I had a fantastic experience with customer service, ordering online, and receiving my purchase. I highly recommend Brilliant Earth, their rose gold options, their moissanite gemstones, and the Reina Halo setting!

The best surprise
I had designed my ring and sent it to my fiancé for inspiration. He went ahead and bought the exact ring! It's absolutely gorgeous and you cannot tell that it wasn't a mined diamond! He said ordering the ring online was a breeze, shipping was reasonably fast, and the payment plans were manageable.

Adorable little details!
Incredibly happy with this ring. When my fiancé and I were looking at the halo styles, we went back and forth between the Reina and the Credenza. Glad we went with the latter, as I am thrilled by all the little details on this setting. It's everything I could have hoped for-just like my fiancé :)

Blown away
When my fiancé opened the box upon proposing, I was so stunned at the absolute beauty of this ring. He purchased the 18k white gold with a 2.15 emerald cut diamond. I cannot stop staring at the sparkle. The setting is so vintage looking and just mind blowing. We went to Mammoth Lakes, ca and he asked me to "grow old with him". I couldn't have picked a more gorgeous ring to wear for the rest of my life and I hope this is the ring that is passed down for generations to come. Thank you Brilliant Earth for helping my fiancé pick my dream ring!

Perfect in every way ✨
Such a classic vintage feel! Love everything about it and my fiancé had an amazing experience with the buying process. They provided excellent service and accommodations to us being in Hawaii and made the whole process go so smoothly.

She is ecstatic!
I bought this as an engagement ring for my fiancé. She definitely hinted hard that she was ready after 4 years, a house, and two dogs together. She started looking around and quickly fell in love with this ring. The setting is interesting, the in-laid synthetic diamonds add a little extra to the center 2-carat equivalent 8mm super premium moissanite. We got engaged end of March 2021 and she's still taking pictures and gushing about it. Very happy that she's so happy.

In LOVE with my engagement ring
My ring has a sapphire as the center stone, and it looks amazing against the rose gold. Adds just the right amount of vintage. It is absolutely perfect, and my mind is at ease knowing that it was ethically sourced. It has only been a few days, and I have already gotten so many compliments!

Love this ring!
I love this ring so much. It is so scary to pick something so important as an engagement ring online, without seeing it in person - but, I wouldn't change a thing. I saw this ring on the website and kept hinting to my now husband, and thankfully he listened. It is so gorgeous. My current ring size is 9. I wanted rose gold to be slightly different, my wedding band is a matching band but in white gold, and they complement each other well. The stone is 7mm Moissanite - and it sparkles perfectly. There is no need to second guess this ring!

The Ring is Perfect
My fiance surprised me with this setting in October and I love it! We had picked out the loose diamond together at the Chicago showroom in March and I had no idea he had the diamond put into this beautiful setting. I have a size 6ish hand and my ring is a 0.8 carat oval diamond in a platinum setting. I love it and I can't stop looking at it!

This ring is GORGEOUS and exceeded all my expectations!!
I've been engaged for about six months now, and this is actually my second engagement ring - I ordered my first one for myself from a different retailer (my fiance has been working on paying off debt before we get married, so I was in a better financial position to pay for it). It was a non-returnable custom design, and unfortunately I was disappointed with the result when it did not turn out like I had envisioned. Shortly after receiving that ring, I discovered the Reina engagement ring from Brilliant Earth, and I had been obsessing over it ever since. Finally, with encouragement from my fiance, I ordered the Reina ring in platinum with a 2 carat, oval cut violet sapphire. Knowing that it could be returned if it did not meet my expectations gave me peace of mind, but let me tell you...this ring is staying!! The Reina is everything I hoped for and more. The band is so delicate and sparkly, and the halo is stunning. In the past I haven't been a big fan of halos, but the unique shape of this one just makes it look so regal and elegant. The sapphire is 9.2 x 7.1 mm and fits perfectly in the setting. I'm obsessed with looking at it in different lights - the sapphire appears to be medium-to-light indigo under fluorescent light, vivid blue in direct sunlight, dark indigo with flashes of lilac under LEDs, and a neat peachy-pink under a black light. Best of all, this ring is way prettier than the first ring I ordered, and only about 1/4 the cost! If you're considering ordering this ring and you're between sizes, definitely go with the smaller size, or even a half size below that. Because the band is so delicate, it will fit a little more loosely than most rings with slightly thicker bands. Some may find it too delicate, but it's perfect for my taste! I can't wait to pick out a wedding band to pair with it. :)

Stunning Unique Morganite Ring
My now fiancé loved the ring! I ordered it in rose gold with a peach morganite stone. I have received so many compliments on getting a non-traditional gorgeous ring! My only con is that the ring was not true to size. My fiancé was sized beforehand and I ordered her size 4.5. However, the ring was too big for her. She took it to a jewler who sized the ring and said it was actually 4.75.
December 8, 2018
Love this!!
My fiancé just proposed with the Reina and it is so beautiful! The center diamond he picked out is a little over 3/4 karat. I've gotten so many compliments on how unique the band is and how much is sparkles!

A truly "brilliant" ring
Beautiful ring. Very elegant. So sparkly. Looks just like the picture, only it doesn't have as many diamonds on the outside as shown. Other than that, my fiancé absolutely loves it, can't stop looking at it. She always get comments on how unique it is. She loves the delicate band.
December 8, 2017
Love my ring!
Love my ring, it's so beautiful! I will say that it does not look like what I ordered with the estimate. Just under 2 carats the halo is more rectangular than what is shown on the page. Nonetheless, I still love it. I've gotten a ton of compliments about it being unique.
February 21, 2019
Very pretty and unique setting, but six loose diamonds
The setting was as beautiful as in the picture and the diamond we added to it was fantastic! We chose to take it to a nearby jeweler to have it sized down instead of sending it back to brilliant earth so that we wouldn't risk having it go through shipment again. Thankfully the jeweler said that the diamond was very nice, it was the exact size we ordered, and he even showed us the serial number on the diamond under a microscope. Unfortunately, he found that six of the small setting diamonds were loose so we had to pay to have them tightened at $20 each, before it could be sized. We thought about calling Brilliant Earth and fighting this but again did not want to send it back out in shipping so we paid the jeweler to tighten them. For a brand new and very expensive ring, none of those diamonds should have been loose. This was our only complaint about purchasing the ring through Brilliant Earth.
September 6, 2018
BAD QUALITY
The ring was delivered on time, however many issues immediately arose. The box had zero paperwork regarding grading, etc. Diamonds on the setting immediately started to FALL OUT.

A carat is the unit used to measure a diamond's weight. One carat equals 200 milligrams or 0.2 grams. Although carat weight and the size of a diamond are related, the carat does not directly measure diamond size.
Describes the alignment of the facets of the diamond. If facets are misaligned, the diamond may poorly reflect light. Symmetry is graded from Ideal / Excellent, Very Good, Good, Fair, or Poor. Symmetry grades of Good or higher have the least effect on the brilliance of the diamond and are suitable for the finest quality jewelry. Certain gem labs, such as Gemscan, incorporate Symmetry into an overall Cut grade.

The height of a gemstone, from the culet to the table. Depth % is the height of the diamond as a percentage of the girdle diameter.

Diamonds are given three measurements to specify their dimensions. For fancy shaped diamonds, the measurement specifies length x width x depth. The length is the larger dimension as you view the diamond from the top and the width is the smaller. The depth is the height of a gemstone, from the culet to the table. The measurements determine the length to width ratio and can indicate the quality of cut of the diamond.
For round diamonds, the measurement specifies diameter 1 x diameter 2 x depth. Round diamonds are never quite perfectly round given they are cut by humans. They are given two measurements for diameter to indicate the maximum and minimum diameter. These two diameters vary slightly, but should not vary by very much.
Describes the finish of the facets of the diamond. Polish is graded from Ideal, Excellent, Very Good, Good, Fair, or Poor. Polish grades of Good or higher have the least effect on the brilliance of the diamond and are suitable for the finest quality jewelry. Certain gem labs, such as Gemscan, incorporate Polish into an overall cut grade.
Vermeil (pronounced vehr-may) is sterling silver that is plated in a thick layer of gold, making it more resistant to signs of wear. Our vermeil is 14K yellow or rose gold that is a minimum of 2.5 microns thick.
Tantalum is a natural chemical earth metal. It belongs to a class of metals known as refractory metals, which are defined by their strong resistance to heat and wear.

Color is the natural color visible in a diamond and does not change over time. Colorless diamonds allow more light to pass through than a colored diamond, releasing more sparkle and fire.

A diamond’s clarity refers to the presence of impurities on and within the stone. When a rough stone is extracted from carbon deep beneath the earth, tiny traces of natural elements are almost always trapped inside. These elements are called flaws or inclusions because they are formed naturally and are unique to each stone.

The cut refers to the angles and proportions of a diamond. The cut of a diamond—its depth and width, and the uniformity of the facets—determines its beauty. The skill with which a diamond is cut determines how well it reflects and refracts light.

Exquisite quality cut to create the optimal combination of brilliance and fire. Reflects nearly all light that enters the diamond.

Length-to-Width Ratio –The length-to-width ratio compares the length of a diamond to its width to show how elongated a fancy-shaped diamond appears when viewed from the top. Length-to-width ratio is a matter of personal preference with some individuals preferring a more elongated shape and others a more equal or square shape. The most popular length-to-width ratios for fancy shapes are below.
Ex. A princess-cut diamond that measures 5.05 mm long by 5.00mm has a length-to-width ratio of 1.01 (5.05/5.00), and will appear perfectly square.
Most popular length-to-width ratios:
Princess: 1.00-1.05
Radiant: 1.00-1.05
Asscher: 1.00-1.05
Cushion: 1.00-1.05
Elongated Cushion: 1.20-1.49
Heart: 0.90-1.10
Emerald: 1.30-1.40
Oval: 1.30-1.70

The length of the chain will determine where the necklace will fall, whether choker length, at or below the collarbone, or at the neckline. We measure the length from the beginning of one end, to the end of the other, including the clasp (which may add an additional .75 inches). Different lengths are worn for different occasions and different outfits. The most common length is the 18" length, which typically falls at the collarbone. 16": Choker length. Accentuates her neckline. 18": At collarbone. Classic length. 20": A few inches below collarbone. 22": At or above neckline. For more dramatic, stylish look.
The dimensions of the gemstone are the length and width of a gemstone as it appears from the top view. Dimensions represent the size of the gemstone more accurately than carat weight.
For colored gemstones, dimensions are the best way of accurately measuring size. These dimensions are accurate plus or minus 0.2mm.
Color is used to describe the color present within a gemstone. Color is described in terms of tone and hue. Brilliant Earth carefully selects gemstones with even color distributed throughout the gemstone.
Clarity is used to describe the presence of impurities on and within the gemstone. If the clarity of gemstones is specified as "eye clean", no visible impurities or flaws will be seen with the unaided eye. If the gemstone is "moderately included," there may be moderate flaws that are visible upon examination.
Many aquamarines are heated in a controlled environment to ensure their blue color is as vibrant and pure as possible. This heat treatment is an accepted industry standard which mimics natural processes to maximize the beauty of the stone.

For a collection of diamonds, Brilliant Earth includes the GIA Diamond Origin Report to help trace the diamond from its source to its final polished state by uniquely leveraging advanced scientific analysis to deliver technical rough-to-polish diamond matching. GIA collects and analyzes physical measurements, spectroscopic data, and imaging of the diamond as a rough crystal before it is cut and polished. A unique identification number is assigned to the rough diamond. GIA later uses this data to scientifically match the polished diamond to the original rough crystal it came from.
Hearts and Arrows diamonds are highly coveted because they’re cut with high precision and exceptional craftsmanship. These round brilliant diamonds are cut to proper proportions and crafted with a high degree of facet precision to exhibit a sharp pattern of eight arrows in the face up view and eight small hearts from the pavilion. The cut grade of hearts and arrows is evaluated by its facets appearance - exhibiting excellent face-up appearance with brightness, scintillation, and fire.

Diamond cut should not be confused with shape. Shape refers to the general outward appearance of the diamond, not its reflective qualities. Brilliant Earth currently carries the following shapes:
Cut should not be confused with shape. Shape refers to the general outward appearance of the gemstone, not its reflective qualities. Brilliant Earth currently carries the following shapes:
For colored gemstones, dimensions are the best way of accurately measuring size. These dimensions are accurate plus or minus 0.2mm.
The length of the chain will determine where the necklace will fall, whether choker length, at or below the collarbone, or at the neckline. We measure the length from the beginning of one end, to the end of the other, including the clasp (which may add an additional .75 inches). Different lengths are worn for different occasions and different outfits. The most common length is the 18" length, which typically falls at the collarbone. 16": Choker length. Accentuates her neckline. 18": At collarbone. Classic length. 20": A few inches below collarbone. 22": At or above neckline. For more dramatic, stylish look.
Color is used to describe the color present within a gemstone. Color is described in terms of tone and hue. Brilliant Earth carefully selects gemstones with even color distributed throughout the gemstone.
Clarity is used to describe the presence of impurities on and within the gemstone. If the clarity of gemstones is specified as "eye clean", no visible impurities or flaws will be seen with the unaided eye. If the gemstone is "moderately included," there may be moderate flaws that are visible upon examination.
The type of accent diamonds in this engagement ring setting will match the type of your selected center diamond. If a natural center diamond is selected, then the accent diamonds will be natural diamonds. If a lab grown center diamond is selected for this setting, then the accent diamonds will be lab grown.
Diamonds are given three measurements to specify their dimensions. For fancy shaped diamonds, the measurement specifies length x width x depth. The length is the larger dimension as you view the diamond from the top and the width is the smaller. The depth is the height of a gemstone, from the culet to the table. The measurements determine the length to width ratio and can indicate the quality of cut of the diamond.
For round diamonds, the measurement specifies diameter 1 x diameter 2 x depth. Round diamonds are never quite perfectly round given they are cut by humans. They are given two measurements for diameter to indicate the maximum and minimum diameter. These two diameters vary slightly, but should not vary by very much.
The largest facet of a gemstone, located at the top. Table % is the table width as a percentage of the girdle diameter.

The height of a gemstone, from the culet to the table. Depth % is the height of the diamond as a percentage of the girdle diameter.

Describes the alignment of the facets of the diamond. If facets are misaligned, the diamond may poorly reflect light. Symmetry is graded from Ideal / Excellent, Very Good, Good, Fair, or Poor. Symmetry grades of Good or higher have the least effect on the brilliance of the diamond and are suitable for the finest quality jewelry. Certain gem labs, such as Gemscan, incorporate Symmetry into an overall Cut grade.
Describes the finish of the facets of the diamond. Polish is graded from Ideal, Excellent, Very Good, Good, Fair, or Poor. Polish grades of Good or higher have the least effect on the brilliance of the diamond and are suitable for the finest quality jewelry. Certain gem labs, such as Gemscan, incorporate Polish into an overall cut grade.
The narrow rim around the widest part of a diamond, separating the crown from the pavillion.
The tiny facet at the bottom tip of a gemstone. The optimal culet should be pointed or very small (graded "small" or "none").
Describes the diamond's response to ultraviolet light. In diamonds with strong or very strong fluorescence, there may be some interference with the flow of light which causes a milky or oily appearance.
Length-to-Width Ratio –The length-to-width ratio compares the length of a diamond to its width to show how elongated a fancy-shaped diamond appears when viewed from the top. Length-to-width ratio is a matter of personal preference with some individuals preferring a more elongated shape and others a more equal or square shape. The most popular length-to-width ratios for fancy shapes are below.
Ex. A princess-cut diamond that measures 5.05 mm long by 5.00mm has a length-to-width ratio of 1.01 (5.05/5.00), and will appear perfectly square.
Most popular length-to-width ratios:
Princess: 1.00-1.05
Radiant: 1.00-1.05
Asscher: 1.00-1.05
Cushion: 1.00-1.05
Elongated Cushion: 1.20-1.49
Heart: 0.90-1.10
Emerald: 1.30-1.40
Oval: 1.30-1.70
Pear: 1.45-1.75
Marquise: 1.75-2.30
Color is the natural color visible in a diamond and does not change over time. Colorless diamonds allow more light to pass through than a colored diamond, releasing more sparkle and fire.
Absolutely colorless or icy white. The highest color grade—extremely rare and most expensive.
A diamond’s clarity refers to the presence of impurities on and within the stone. When a rough stone is extracted from carbon deep beneath the earth, tiny traces of natural elements are almost always trapped inside. These elements are called flaws or inclusions because they are formed naturally and are unique to each stone.

Flawless with no internal or external flaws. Extremely rare and valuable.
The cut refers to the angles and proportions of a diamond. The cut of a diamond—its depth and width, and the uniformity of the facets—determines its beauty. The skill with which a diamond is cut determines how well it reflects and refracts light.
Exquisite quality cut to create the optimal combination of brilliance and fire. Reflects nearly all light that enters the diamond.
Top 3% of diamond quality based on cut.
A carat is the unit used to measure a diamond's weight. One carat equals 200 milligrams or 0.2 grams. Although carat weight and the size of a diamond are related, the carat does not directly measure diamond size.
