Frequently Asked Questions

About the Stones

What is moissanite?

Moissanite is a brilliant, durable gemstone naturally found in meteorites, now lab-grown for fine jewelry. It has more fire and brilliance than a traditional diamond, ranks 9.25 on the Mohs hardness scale, and costs a fraction of the price.

Is moissanite a real gemstone?

Yes. Moissanite is a real, certified gemstone — not a simulant. Every Stella Nera piece comes with an independent GRA certificate verifying authenticity, color, and clarity.

Will it pass a diamond tester?

Yes — most consumer diamond testers detect heat conductivity, which moissanite shares with diamond. This is one of moissanite's defining qualities and why it's considered the closest alternative to a diamond.

Does moissanite scratch or lose brilliance over time?

No. At 9.25 on the Mohs scale, moissanite is exceptionally hard. With proper care, it retains its brilliance indefinitely.

About the Settings

What metal are your pieces made of?

All Stella Nera pieces are crafted in S925 sterling silver, often plated in platinum or white gold for added durability and finish.

Will sterling silver tarnish?

Sterling silver naturally develops a patina over time. With proper care (see Care Instructions), tarnish is minimal and easily removed. The plating extends the life of the finish significantly.

Is the jewelry hypoallergenic?

Sterling silver is generally well tolerated, but some sensitive skin may react to trace metals in alloys. If you have known metal sensitivities, we recommend consulting a jeweler before purchase.
