9 Unique Custom Engagement Rings

Celeste Perron

The Brilliant Earth custom design team loves to help couples bring their unique vision to life. With all of their friends getting engaged at once, some people want to have a ring that nobody else has.

Others have an idea of their ideal ring design in their heads and need help creating it. Still others have seen a ring that they like sold elsewhere but want us to make a similar style using ethically sourced gemstones and recycled precious metals. Whatever the reason a couple goes custom, an absolutely breathtaking, utterly unique ring is always the outcome. Here are some gorgeous custom engagement rings we’ve created for Brilliant Earth couples:

Square Halo Eternity Ring

The Square Halo Eternity Ring is an antique-inspired style featuring a peach sapphire (definitely a shade you don’t see every day) in a platinum setting. The round sapphire is surrounded by a square halo for a beautiful effect.

Dynamic Twist Solitaire Ring

A contemporary yet nature-inspired style, the Dynamic Twist Solitaire gives the illusion of multiple layers of vines intertwining to accent a dazzling princess cut diamond. The diamond is held aloft by a four-prong setting that maximizes its brilliance.

Floating Round Bezel Halo Ring

In the ultra-glamorous Floating Round Bezel Halo with Milgrain ring a dazzling bezel-set diamond is encircled by a halo of diamond accents, embellished with delicate milgrain detail. Diamonds on the band bring extra shimmer, for a contemporary look with antique romance.

Vintage Inspired Diamond Filigree Ring

This Vintage-Inspired Diamond Filigree Ring was designed to subtly evoke Art Nouveau-era artistry. The dazzling center diamond and four twinkling diamond accents are surrounded by lavish detail, with filigree and milgrain embellishing the gallery and shank of the ring.

Sapphire Triple Halo Ring

An oval center sapphire and two half moon-shaped diamonds are all surrounded by glittering diamond halos in the Sapphire Triple Halo Diamond Ring. Beautifully designed, this ring exudes glamour from every angle.

Marin Vintage Ring

A reproduction of a romantic vintage style, the Marin Vintage Custom Reproduction Ring is truly a standout statement piece. The yellow gold floral design features darkened inner petals which allow the center diamond to shine to its fullest brilliance, while the deep grooves along the band give the piece an organic feel.

Vintage Inspired Marquise

A contemporary take on Art Deco design, the Vintage-Inspired Marquise Diamond Ring features geometric frames, milgrain detail, and plenty of glittering diamonds to create a glamorous one-of-a-kind look.

Trifoliate Diamond and Sapphire Ring

The Trifoliate Diamond and Sapphire Ring is as feminine and beautiful as it is one of a kind. The round brilliant cut diamond features distinctive paddle-shaped prongs, and three deep blue sapphire accents on each side. The sapphires shimmer from leaf-shaped, milgrain-embellished frames, for a look at once antique and nature-inspired.

Macy Estate Ring

A diamond lover’s dream, the Macy Estate Custom Reproduction ring features a beautiful round brilliant center diamond surrounded on all sides by diamond accents in geometric, milgrained frames.

These were not what l consider stunnig, they were all white diamonds. Stunning, unusual, drop dead beautiful would be a large yellow or blue, or pink, or green or purple diamond surrounded by whit diamonds. Another way would be large white surrounded by colored diamonds.

The one with the sapphires on the side is the want I just have to have. I’m sending the photo to my boyfriend…he needs some input so it appears that “it was his idea” lol. Thank you for sharing the photos, now I know what I really want :).

These mostly grotesque rings with way too much “gingerbread” will look extremely dated by the time of the first grandkids.

They were all absolutely gorgeous. My favorite was narrowed down to 2. The yellow gold flower with the large round diamond in the center, and the art deco marquise that was right after it.
