Love my new earrings. They are very sparkly!
By Ann K.
I was very skeptical about ordering an engagement ring ONLINE…. It’s so risky. But with some research I discovered that Gema & Co. didn’t have any negative reviews so I decided to give them a try. I chose my ring and it only took exactly 19 days for me to receive it! I was honestly expecting it to take a little over a month. The ring is too small and tight in my finger but I’ll make it work. That is not the company’s fault at all. Now all I have to do is see if it’ll last. The ring did come with a lifetime warranty though so hopefully that will give me some peace of mind.Besides the fit, I’m happy.

I couldn't be more pleased with the Charles and Colvard loose moissanite 3.6 carat DEW that I purchased from Gema and CO. I had it set in my original wedding ring. My Goldsmith/jeweler highly recommended the Charles and Colvard moissanite over other moissanite he has worked with. It looks amazing! Pictures just don't do it justice!

Received the ring and loved it. Had an issue with one of the small stones falling out and customer service immediately sent me a postal label to get it fixed and had the ring back to me in under a week. Strong recomend!

I have nothing but fabulous things to say about Gema & Co. I am beyond pleased with both of my rings. I emailed asking about having them soldered and the company did the service and had them back to me within 2 weeks! Customer service had fantastic communication throughout the process!
