Let customers speak for us
from 401 reviewsMy fiancé proposed to me with this ring yesterday at Fort Sumter National Monument in Charleston, SC. It was absolutely beautiful. This ring is so gorgeous. The band is perfect and the moissanite is stunning. I could not be happier with my ring. I love that it is ethically sourced as well.
OMG THIS RING WAS GREAT! My wife has other rings and this one sparkled much more. Very high quality. Iwould 100%recommend this to anyone. Writing this review is the least I can do
The 1.5ct size is a beautiful setting for a size 4.25 ring! The only thing to keep an eye out for is that these three stone settings may not work with all styles of wedding bands. If you have a particular image about how you want this to look with a wedding band consider the wedding band options before buying to make sure it will look how you want it to look!
Very impressive setting and the diamonds are flawless. Would love to order another piece soon. Highly recommended.
Fantastic workmanship, brightness, cut, fit, etc. I cannot say enough good things about this ring and company!!
My engagement band is very low set so I had a hard time finding a wedding band that fits around it. My best option was to do the open pave band, but with a custom gap width. Throughout this process, Liz was extremely helpful and patient. There is also a lot of consistency in who you talk to via chat, email, etc. I had worked with Liz the whole time; she guided me through figuring out what size gap I need and any other ring accommodations to consider that I hadn’t thought of. She was super personable, as well. The ring turned out perfect, and I received it very quickly. Everything was all around a pleasant experience - highly recommend!
Great ring, great service. Ring showed up on time and ready for proposal! Thank you!
I absolutely love Gema & Co! From the very first inquiry, their team was incredibly communicative, patient, and helpful throughout the entire process. The Oval Halo ring in 14K yellow gold is absolutely stunning — the craftsmanship is impeccable and the stone is even more beautiful in person than in the photos. The quality far exceeded my expectations and it arrived beautifully packaged. If you're looking for a jeweler who truly cares about getting every detail right, look no further. I could not be happier and will definitely be a returning customer!
Great service appreciated and working with me
I 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
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.
