Love it!!

I’ve had my ring for almost 3.5 years now and I still love it as much as I did when my husband proposed with it. It has held up great and is still so beautiful. I’m so glad I found this website years ago. Recommend to anyone!

Perfect ring!

Love my ring! I purchased it as a spacer between my engagement ring and wedding band. I reached out to customer service, sent them pics of my engagement ring, and they responded promptly with instructions on where to measure my setting to ensure a proper fit. It looks beautiful and fits great!

Absolutely Stunning

We bought both my engagement ring and wedding band in 14 k gold from Gema and Co and could not be happier. My fiance and I both think this e-ring is the most beautiful ring we have ever seen. The diamond is so brilliant, clear and sparkly - we are blown away! I keep getting so many compliments!
For the engagement ring, Liz provided us with a choice of 3 diamonds within the 2.1-2.5 carat range with IGI certifications and videos (upon request). We went with the 2.5 carat diamond, and she did not charge any extra for the additional 0.5 carats! All diamond choices were “Excellent” for Polish and Symmetry, “None” Fluorescence, D Color Grade, and VS 1 Clarity Grade (meaning top choices for diamonds!).
For the wedding band, I was looking for a simple, elegant look to complement my engagement ring and diamond, and not overpower it. "The Plain" wedding band was perfect. Both sit perfectly flush with each other and their shaft heights also match perfectly. We made customizations to the rings - increased both bands to 2.2mm and changed the e-ring setting to cathedral and a platinum basket. Highly recommend increasing the band (especially pave!) to at least 2 mm to maintain the integrity of the ring/small diamonds.
Liz is extremely responsive and prompt. The customization process was overall pretty smooth, despite some bumps along the way: 1) It took a bit longer than expected to have the renderings created (about a week for each render; we needed to reach out for a status update each time, and then she would send us a render), and 2) there was an error on 2 of the renderings, but it was a quick fix. Overall we are very impressed with the outcome. From start to finish it took about 5.5 weeks to order, create and receive the rings, which is a bit longer than expected. If we had to do it again, we would absolutely order from Gema and Co and highly recommend!

Beautiful, simple, classy

I was looking for a simple, elegant look to compliment my engagement ring and diamond, and not overpower it. This wedding band was perfect. I paired it with the oval pave engagement ring that Gema and Co sells, and it sits perfectly flush with it (the shaft height also matches perfectly). I increased this band to 2.2mm (as well as my e-ring). It’s perfect. Couldn’t be more happy with my purchase. I also embarrassingly fell while wearing this wedding band out on a run (of course the first day wearing it!) and Liz has offered an easy process to get it repaired. Very pleased and impressed!

I couldn’t be happier with my rings that I’ve bought from you guys. I’ve had my ring since Feb 2023 and it’s easy to clean, feels secure in its clasp, and still so so beautiful. I get constant compliments. Thank you!!

I love it!!

My fiancé got my engagement ring from Gema&Co, and I really wanted for my wedding and to match my engagement ring really well!! I ended up getting the plain since my engagement ring is the pave, so it’s perfect!! And I love that the gold is the exact same and that makes me really happy :)
