What could be more glamorous than a 3 carat diamond ring? A classic, ever-coveted choice, 3 carat diamond rings come in all traditional diamond shapes – round, oval, cushion, princess, pear, emerald, asscher, heart, marquise, and radiant. 3 carat diamonds also come in wide-ranging grades of cut, color, and clarity (alongside carat these categories comprise the famous 4 Cs). Lustrous plain metal bands, pavé diamond bands, and three stone settings can all compliment a 3 carat diamond ring center stone perfectly, so choose a setting that resonates with you and your partner's style.

To learn more about 3 carat diamond engagement rings, please contact our jewelry specialists who are happy to answer your questions via phone, chat, virtual or in-person appointment.

How much is a 3 carat diamond ring?

The price of a 3-carat diamond ring depends on several factors such as the quality of the diamond, the shape and cut of the stone, and the metal used for the band. Generally, a 3-carat diamond ring can cost anywhere from $10,000 to $100,000 or more. Diamonds with high clarity, color, and cut grades will be more expensive, as well as those with unique shapes or designs.

Can I insure a 3 carat diamond ring?

Yes, it is possible to insure a 3-carat diamond ring. It is recommended to insure expensive jewelry like diamond rings, as they can be lost, stolen, or damaged. Many insurance companies offer coverage for jewelry, including engagement rings. To insure a 3-carat diamond ring, you will need to have it appraised by a professional and provide the insurance company with documentation and photographs. The cost of insurance will depend on several factors, including the value of the ring, where you live, and the type of coverage you choose. At Brilliant Earth, we partner with Lavalier Insurance, a jewelry-specific insurer.

Is it possible to get a 3 carat diamond engagement ring on a budget?

While a 3 carat diamond engagement ring can be expensive, there are ways to stay within a budget. Here are some tips:

Consider a lower color or clarity grade: A diamond with a lower color or clarity grade can be less expensive while still looking beautiful.
Choose a simple setting: A simple setting style can be less expensive than a more elaborate design.
Consider alternative gemstones: If a diamond is not in your budget, consider alternative gemstones such as moissanite or sapphire, which can mimic the look of a diamond at a lower price.

What are the different types of settings available for a 3 carat diamond ring?

When it comes to 3 carat diamond rings, there are several types of settings that you can choose from. Here are some of the most popular options:

Solitaire: This is the most classic and traditional setting for an engagement ring. It features a single diamond on a plain metal band.
Halo: A halo setting features a center diamond surrounded by a ring of smaller diamonds, which can make the center stone appear larger and more brilliant.
Three-stone: A three-stone setting features a center diamond flanked by two smaller diamonds on either side. It represents the past, present, and future of a relationship.
Pavé: In a pavé setting, small diamonds are set closely together to create a sparkling, diamond-encrusted band.
Channel: A channel setting features diamonds set into a channel in the band, with no prongs or other metal visible.
Bezel: In a bezel setting, the diamond is surrounded by a metal rim that holds it securely in place. This can be a good option for active people, as it offers more protection to the diamond than some other settings.

What are the most popular diamond shapes for a 3 carat ring?

The diamond shape you choose for a 3 carat ring is a matter of personal preference, but some shapes tend to be more popular than others. Here are some of the most popular diamond shapes for a 3 carat ring:

Round: This is the most classic and timeless diamond shape, and it's also the most popular for engagement rings.
Princess: Princess-cut diamonds are square or rectangular in shape, with pointed corners. They're a popular alternative to round diamonds and can be more affordable.
Cushion: Cushion-cut diamonds are square or rectangular with rounded corners and have a vintage feel. They're also known as "pillow-cut" diamonds.
Emerald Cut: Emerald-cut diamonds are rectangular with cut corners and have a step-like appearance. They're a popular choice for those who prefer a more understated look.
Oval: Oval-cut diamonds are elongated and have a flattering shape that can make fingers look longer and slimmer.
Pear: Pear-shaped diamonds are a combination of a round and a marquise shape, with a tapered point on one end. They're a unique and elegant choice for an engagement ring.
