Perfect Fit With Briliant Earth Engagement Ring

My fiance purchased an engagement ring from Brilliant Earth and I wanted a curved band to pair with it, but pricing for gold is now outrageous. Gema had much more reasonable pricing and I'm so happy I reached out to them to see if they could pair this with my ring.

They asked for a few photos and measurements of my center stone and were able to get the ring made for me. It fits so beautifully! Thank you!

A Stunning Trio Marquis Ring from Gema&Co

I recently purchased the Trio Marquis engagement ring from Gema&Co, and I couldn’t be more impressed. The design is absolutely stunning — the marquise center stone paired with the side stones gives it such an elegant and timeless look. It has incredible sparkle and looks even better in person than it did online.

The craftsmanship is excellent, and you can really see the attention to detail. The entire process with Gema&Co was smooth, professional, and seamless from start to finish. I highly recommend them if you’re looking for a beautiful, high-quality engagement ring at a great value.

Great ring

I got the marquise bezel for her and she loves it. She’s already received compliments from strangers after just a day of having it. I don’t know much about rings so the customer service rep helped out a ton. Really happy with the ring and definitely will recommend to others

Simple and Thin

I like this simple, thin band with a small stone. The diamond is smaller than I'd imagined, but it's perfect for my size 4 finger and pairs beautifully with my engagement ring without competing for attention. Perfect for daily wear!

9x7 oval moissanite. size 6 finger

i was nervous ordering online for a moissanite engagement ring. but Gema&Co exceeded all of my expectations. the ring took longer than expected because they found a flaw in the stone but the replaced it, no extra cost and expedited the shipping. i am so impressed with their customer service and craftsmanship.
