Product Description

A dark fairytale told in deep green. The Lilith Coffin Cut Emerald & Green Fire Opal Couples Ring Set pairs her blackened-silver emerald stack—crowned by a dramatic coffin-cut center—with his black tungsten band glowing with crushed green fire opal. For the couple whose romance runs a little gothic, a little otherworldly, and entirely their own.

Three-piece set Coffin-cut emerald Green fire opal band Blackened silver + tungsten May birthstone color His & hers

Two hands, one dark romance

Some couples want candlelight and shadow rather than sunshine and sparkle. This three-piece his-and-hers set was made for them: her coffin-cut emerald engagement ring and matching band stack into a single striking silhouette, while his domed black band carries a river of green fire opal that seems to glow from within. Coordinated in deep green and darkened metal, it's a favorite among our dark-romance couple rings and gothic sets—an alternative to the traditional. New to shopping for a pair? Our guide to the best matching rings for couples in 2026 is a beautiful starting point.

Her Rings

A two-piece stack in solid 925 sterling silver with a blackened black-ruthenium finish, centered on a coffin-cut simulated emerald (approx. 2 ct) framed by simulated diamond (CZ) accents, with a matching shadow band.

His Ring

A comfort-fit, domed black tungsten carbide band inlaid with crushed green fire opal—rugged, scratch-resistant, and quietly luminous.

Coffin-cut emerald & green fire opal

Her center is a coffin-cut simulated emerald—an elongated casket silhouette hand-set for a rich, saturated green, the storied color of the May birthstone. Emerald has symbolized love and rebirth for millennia; our emerald and May birthstone guide traces the lore. His band answers it with crushed green fire opal, so the pair reads as one deep-green story across two hands.

Metals & everyday wear

Her rings are solid 925 sterling silver finished in black ruthenium—a rare platinum-family metal—for a deep gunmetal, blackened-silver glow; his is black tungsten carbide, one of the hardest, most scratch-resistant metals in fine jewelry, with a comfort-fit interior. Both are hypoallergenic and nickel-free, and her rings can be upgraded to solid gold on request. You'll find more pairings in our gemstone couples rings.

We adore them!!

They're SO beautiful we're so happy with them. Looking forward to getting married !!

We're thrilled to hear you love the rings! Congratulations on your upcoming wedding!

Perfection!

I am absolutely obsessed and in love with this set! After my fiancé lost his ring when we went on a cruise a couple years ago, we've been looking for new rings. I wanted to get a matching set with him to make it more special. I’ve gotten so many ads for this company on my phone and I’m so happy I checked it out! It was hard to choose from all the options because I loved them all! We found the perfect fit for the both of us. He’s so happy to have a ring again and I love seeing it. I put this ring on and haven’t taken it off for anything. I highly recommend this company as well as this set of rings! Well worth the money and much more affordable than other jewelry companies.

Absolutely stunning

I was so excited for this ring to come and it surpassed every expectation! I used to never wear my wedding rings and now I haven't taken the ring off since it arrived!

We love them!! Well

We love them!! Well made

Worth Every Dollar!!

It showed up faster than expected!! The rings are beautiful! I plan on getting quite a few more in the future!

Gorgeous set of rings at an incredible price. Love em.

The Lilith Coffin Cut Emerald & Green Fire Opal Couples set arrived on time beautifully boxed. They are exactly as described and very well made from their appearance and feel. We are so happy that we chose this ring set as our 20th anniversary gift to each other. The Emerald is such a beautiful green and my husbands band is just amazing. He loves it, the ring is smooth and has a good weight. The band is the perfect width with that pretty sparkle of the opal running around the middle. We are telling everyone we know about this company and these beautiful rings. The cost is so great too. One day I hope to own another just because there are so many pretty rings available.
