What is moissanite?
Moissanite is a gemstone made of silicon carbide (SiC). First discovered in a meteor crater, today it’s grown in advanced labs to achieve outstanding clarity and fire. Its high refractive index and dispersion produce a vivid, lively sparkle.

Frequently asked questions
What’s the difference between moissanite and a lab diamond?
They’re different materials. Moissanite is silicon carbide (SiC); diamonds are pure carbon. Both are durable and brilliant, but moissanite shows more colorful “fire” and typically costs less.
Will moissanite go cloudy over time?
No—quality moissanite does not cloud. It can collect oils or residue with wear; a simple clean restores sparkle.
Does moissanite pass a diamond tester?
Thermal-only testers may register moissanite as diamond. Modern multi-testers (thermal + electrical) distinguish between them.
Do you offer buyback for moissanite and gold?
Yes. We offer 80% buyback on eligible Giolleria moissanites and 100% of net gold value at the day’s applicable rate. Terms apply—contact us for details.
What is the Giolleria Brilliance Mark?
It’s our house standard for cut precision, optical performance, and finishing. Each stone is inspected before it earns the Brilliance Mark note on your invoice or product card.
How do I keep it sparkling?
At home: warm water + mild soap + soft brush. For a quick refresh, use a lint-free cloth. Schedule periodic professional cleanings.
