Adjustable Sugar-Cube Moissanite Ring | 925 Sterling Silver

$187.50

A square-cut moissanite held in a plain, unadorned frame, sized to sit flat across the finger. The open shank adjusts, so it reads the same on a slim hand as on a full one. Cool white rhodium over solid sterling silver.

  • A square-cut moissanite held in a plain, unadorned cube frame.
  • Open shank adjusts to fit — no sizing appointment needed.
  • Sits flat across the finger, so it wears well next to a band.
  • No engraving and no logo on the outer face.
  • Solid 925 sterling silver, rhodium plated - sterling silver underneath, not plated brass.
  • Ships with the GRA certificate card for the moissanite.

Metal: solid 925 sterling silver (92.5% silver), rhodium plated.

Finish: rhodium, applied over solid sterling silver. The white tone comes from the plating, not from the silver itself.

Also available: this design can be made with an 18K gold plated finish on request.

To keep the finish looking its best, keep the piece dry and store it separately.

Country of origin: China.

Certificate: each piece ships with its GRA certificate card for the moissanite, carrying the stone's details and a certificate number. Keep it with the piece.

Stone type: moissanite, a gemstone in its own right, disclosed as moissanite and not sold as any other stone.

Wear the ring last when dressing and take it off first at night. Keep it away from perfume, chlorine, hairspray and cleaning products. Wipe it with a soft dry cloth rather than a polishing compound, which wears the plating down. Store it in its pouch, away from harder pieces. Sterling silver will darken naturally over time; the rhodium plating slows this, and the piece can be re-plated in future if you wish.

Composition

Laboratory-grown stones are the same mineral, with the same chemical formula and the same crystal structure, as their mined counterparts. Moissanite is silicon carbide (SiC).

How it is grown

Moissanite is grown in a laboratory. Natural moissanite is extremely rare and is not used in commercial jewellery. It is silicon carbide (SiC), crystallising in the hexagonal crystal system.

No fillers

Moissanite is a single crystal. It is not assembled or bonded, and it is not filled, oiled or clarity-enhanced. Coloured moissanite is usually produced by a metallic surface coating — a treatment; where a piece carries a coated stone, we say so on its product page, because the coating can scratch or wear.

Certificates

Every moissanite piece ships with its GRA certificate card for the stone. The card ships with your order and does not add to dispatch times.

Finish and durability

Rhodium or 18K gold surface layer over 925 sterling silver. Both finishes have passed human sweat testing carried out by our supplier, and both are made for long-term, everyday wear. If a finish needs refreshing within two years of purchase, re-plating is free.

Material & Care

Made in 925 sterling silver with a rhodium or 18K gold surface layer, chosen with sensitive skin in mind. Stones are laboratory-grown, so small variations in shape and tone are part of each piece.
