Frequently asked questions

Each ring pairs moissanite stones with a 925 sterling silver setting (bright plated finish), mounted on a flexible silicone band. Every ring is stamped S925 and comes with its GRA moissanite certificate.

Moissanite is a lab-created gemstone made of silicon carbide. It rates 9.25 on the Mohs hardness scale, harder than sapphire, and shows strong fire and brilliance. It is durable enough for everyday wear.

A metal band is rigid: it can scratch, catch and press on the finger when you grip a racket, a steering wheel or a bag strap. Our silicone band flexes with your hand, so you keep the look of fine jewelry from morning workout to evening dinner.

Yes, that is what it is designed for. The band moves with your hand and stays comfortable for yoga, Pilates, tennis, the gym, the keyboard or long flights.

The silicone band does not mind water, sweat or soap. To keep the silver setting bright for longer, take the ring off before swimming in pool or sea water and before using cleaning products.

Rinse it under lukewarm water with a drop of mild soap, brush the stones gently with a soft toothbrush, then pat dry. Store it in its gift box, away from other jewelry.

Open the size guide next to the size selector on each product page. Our rings come in US sizes 7 to 12. Between two sizes, choose the larger one: the silicone band hugs the finger.
