Brilliant moissanite rings in 925 sterling silver — from delicate everyday solitaires to bold statement carats.

Ships from Irvine, California, with free US shipping and 30-day returns.

What size moissanite ring should I choose?

For everyday wear, 0.5ct–1ct sits subtle and comfortable; 2ct–3ct reads as noticeable date-night sparkle; 5ct is a true statement. All are set in 925 sterling silver and available in standard US ring sizes.

Frequently Asked Questions

What ring sizes do you carry?

Most rings come in US sizes 5–9, though the exact range varies by style — each product page lists its available sizes. Shopping for someone else? Here's how to find her ring size without asking.

Is moissanite durable enough for everyday wear?

Yes. Moissanite measures about 9.25 on the Mohs hardness scale, so the stone stands up well to daily wear. To keep the sterling silver bright, take your ring off before showers, pools, and workouts — here's our full care guide.

Will a moissanite ring pass a diamond tester?

Some handheld thermal testers read moissanite as diamond because the two conduct heat similarly — but moissanite is silicon carbide, not diamond, and we never describe it as one. Full explanation: does moissanite pass a diamond tester?

What if my ring doesn't fit?

You have 30 days from delivery to return an unworn ring in its original packaging for a full refund. Email service@mynsujewelry.com with your order number and we'll reply with return instructions within 1 business day.

Does moissanite get cloudy over time?

The stone itself doesn't fade or yellow — any dullness is usually surface residue from lotion or soap, and warm water with mild soap brings the sparkle back. Details: does moissanite get cloudy or change color?
