Trustpilot
Exceptional service, lasting trust
“I've been dealing with Gema&Co And Liz Weaver for about 5 years now. They have custom made my wife's engagement ring to the exact details I provided, later they polished and cleaned the ring, and most recently they swapped out the original moissanite stone for a Lab Diamond for my 5th year anniversary. All of this throughout 5 years, and they have never missed a beat with timely communication, and excellent service.”

Diamond or Moissanite?
Two extraordinary gemstones. Discover the one that's right for you.
Lab-Grown Diamond Engagement Rings
Experience the timeless brilliance and exceptional durability of real diamonds, created using advanced technology rather than mined from the earth.
Moissanite Engagement Rings
Discover extraordinary sparkle, colorful fire, and exceptional value in a beautiful gemstone designed for everyday wear.
1. Are lab grown diamonds real diamonds?
Yes. Lab grown diamonds are real diamonds with the same chemical composition, crystal structure, and optical properties as mined diamonds. The difference is their origin: they are created in controlled laboratory environments rather than formed underground.
2. What's the difference between moissanite and diamond?
Both are beautiful, durable gemstones suited to everyday wear. Diamonds offer classic diamond brilliance and a hardness of 10 on the Mohs scale, while moissanite has a hardness of approximately 9.25 and produces more colorful rainbow fire. Moissanite also typically offers greater size for the price.
3. Can I customize my engagement ring?
Absolutely. Gema&Co offers bespoke engagement ring design, allowing you to personalize gemstone shapes, sizes, settings, precious metals, and design details. We can also help bring an entirely original ring concept to life.

4. How long does it take to receive my engagement ring?
Gema&Co rings generally require approximately 2.5 weeks for production before shipping. Delivery time depends on the shipping method and destination. Custom designs may require additional time.
