Why Moissanite?
Moissanite is a unique gemstone that looks and feels stunningly similar to a diamond but with its own composition and appeal. And since moissanite is artificially grown, custom moissanite engagement rings will always be more ethical as there are no mining or unfair labor practices involved in the process.
Here’s what sets moissanite apart from other traditional gemstones:
Price
Enjoy luxury without the hefty price tag. Moissanite offers the elegance of a diamond at a fraction of the price. This affordable luxury allows you to design the ring you’ve always dreamt of — without spending several months’ worth of salary.
Durability
Crafted to withstand the test of time, moissanite ranks high on the Mohs scale of hardness, meaning that every piece is resistant to scratches and chips. This exceptional durability gives you the peace of mind of knowing that your jewelry will remain pristine and beautiful for generations.
Sparkle
Shine bright like a (moissanite) diamond! Moissanite’s absolutely stunning sparkle rivals even the finest diamonds, elevating your style with its intense fire and scintillation. Whether you want to go bold and bright or subtle and understated, we can help you shine.
Sustainability
Choose jewelry you can feel good about. As a lab-grown gemstone, moissanite offers a sustainable alternative to traditional diamond mining, with minimal environmental impact and a transparent, ethical supply chain. See our blog post on "how to make moissanite".
Ethics
With a moissanite ring, you can rest easy knowing your jewelry is free from the ethical concerns associated with diamond mining, such as conflict or exploitation. Its lab-grown origin guarantees a socially responsible choice that aligns with your values and integrity.

Custom Moissanite Jewelry Design Tips
New to jewelry design? We’re here to help. Custom moissanite rings are incredibly simple to design with fewer things to consider:
- Gemstone Shape: The shape of your moissanite gemstone greatly influences its visual appearance and brilliance. Popular choices like Round and Princess cuts offer timeless elegance, while unique shapes like Marquise and Half Moon add a touch of uniqueness and individuality.
- Gemstone Size: The size of moissanite gemstones can significantly impact their overall radiance and cost. Larger gems tend to make a bolder statement, yet they’re still affordable compared to diamonds of similar size.
- Ring Setting: The setting of your ring also plays a role in highlighting and complementing the beauty of the moissanite gem. A classic Solitaire setting elegantly showcases the brilliance of the gemstone, while options like Pave or Halo add an extra touch of sparkle and luxury to your design.

Let customers speak for us
from 331 reviewsIn love with the prompt response and communication. The ring looks amazing!

We had issues with a different jeweler with our bezel edge looking very uneven because they apparently didn't have enough skill to evenly fold it or something. Not sure why they couldn't do it, but it looked awful. Cancelled the order and spent the next few months looking for the right jeweler. Gema was actually much cheaper and the ring is flawless. Incredibly grateful to have found you guys. Thank you!

The people who work in this company are some of the most helpful people I've done business with; they always respond to any concerns I may have or fix any issues arising during the purchase. I wholeheartedly recommend them to anyone looking to buy a diamond, ring, or any other type of jewelry.

The Marquise Solitaire is a stunningly elegant ring that combines the timeless sophistication of a marquise-cut diamond with the simplicity of a solitaire design. Its elongated shape enhances the brilliance of the stone while creating a flattering, finger-lengthening effect, making it both unique and classic. Set on a luxurious yellow gold band, this piece exudes warmth and refinement, perfect for those seeking an understated yet striking engagement ring. While its minimalist design highlights the diamond’s beauty, it’s important to ensure proper care for the pointed ends to maintain its durability and charm over time.

Love my recent choice. Found you all through a google search and I was very satisfied with all the service I was provided.

This ring is perfect - we were looking for something simple but beautiful to match my active lifestyle. The bezel setting is one of the most secure options and the light shines beautifully through the bottom of the ring to make it shiny bright! I get compliments everywhere I go.

When I received my wedding band from a different jeweler I didnt like the space between my engagement ring and wedding band. I found GEMA&CO and ordered an open band to help keep my wedding band and engagement ring from scratching each other. The band fits perfectly between the two bands. The price was reasonable.

The ring is absolutely stunning, delicate, and timeless. The amazing customer service makes the experience even better. So happy my fiance and I chose Gema&co!

I was proposed to 2 weeks ago and the ring is drop dead gorgeous. Beautiful center stone and overall craftsmanship. Liz was also so helpful for both of us and responded to all of our questions almost immediately.

Very stunning and simple ring. Fiancé loves it.

Absolutley gorgeous. I lost my real out of my wedding set, and it was a high quality diamond . Unfortunately , I didnt have insurance on it. this diamond is a little bigger , as I’m having it reset. it’s just as beautiful as my lost diamond. I’m extremely pleased!

Was proposed to last week and oh my gosh is this the perfect ring for me. The cener stone is stunning and everything about the ring is chef's kiss. The bezel style just pulls the piece together for me.

My wife wanted a simple and understated emerald diamond ring, and this ring fit the bill to a T. I had a couple questions regarding stone sizing, and Josh was able to assist me with videos showing approximate sizes of all the available stones. Very helpful. The ring was stunning when it arrived and was a slightly larger D color VVS than what I had ordered.

A bit less traditional but it look great. Wife loves it!

Very pleased with my purchase and the company's incredible customer service. My spacer is perfect for between my engagement ring and wedding band!
