Let customers speak for us
from 386 reviewsI was very skeptical at first with it being an online order for an engagement ring but I did the research and they communicated so well and I am so glad I chose them. She was beyond thrilled when she saw how beautiful it was. Definitely would recommend.
I have not taken to my jeweler. I lost one stone in 3 stone ring. I’ll ça back with you
Jewelry was exactly as described - beautiful and elegant. My wife adores it!
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!
Beautiful ring , arrived early!Wonderful communication
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.
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
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!
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.
I love my ring so much and get so many compliments. It’s so classy and gorgeous. Also, fantastic customer service!
Ring in absolutely perfect. I had some questions during production and the customer service was amazing. Highly recommend for anyone looking for quality.
It was perfect. My fiancée loves her new ring! Liz was AMAZING. And it’s perfect I mean literally insane quality!
My rings are beautiful! I love the quality and shine and love the communication process throughout my shopping journey. 100/10 would recommend!
I wanted a more elongated 11x8mm cushion and Josh was incredibly quick to respond and set me up with the custom cut sizing! Ring is gorgeous and everything I've ever dreamed of.
Frequently Asked Questions about Custom Moissanite Rings
Have questions before you create your own moissanite ring? We have answers. If you don’t see your question below, check out our FAQs page for more.
How does moissanite compare to diamonds?
Moissanite is not the same as a diamond, but it offers a similar sparkle, brilliance, and durability at a lower price. Since moissanite is lab-grown, it’s also an ethical, eco-friendly choice for those who value sustainability without sacrificing beauty.
How do I choose the right ring size?
You can find your ring size by using an online sizing chart, measuring the diameter of a well-fitting ring, or visiting a jeweler for professional sizing. We also recommend using a plastic ring sizer, available on Amazon for around $4 with free shipping.
What types of moissanite wedding bands do you offer?
We offer a variety of moissanite wedding bands, including classic styles like eternity bands as well as contemporary designs featuring Pave or Solitaire stones.
What's better, lab diamond or moissanite?
It depends on what you’re looking for, as both lab diamonds and moissanite are remarkable in their own ways. A lab grown diamond closely mimics a natural diamond in look and composition. However, when you build your own moissanite ring, it delivers vibrant fire, durability, and a more affordable alternative.
How long will a moissanite ring last?
A custom moissanite ring can last a lifetime with proper care. Moissanite is nearly as hard as a diamond, making it highly resistant to scratches and everyday wear.
Is it worth buying a moissanite ring?
Yes, moissanite rings are worth buying if you want stunning sparkle, durability, and an ethical, budget-friendly alternative to diamonds. When you create your own moissanite engagement ring, you’re getting a piece with exceptional brilliance that can last a lifetime with proper care.
