4x6mm Oval Moissanite Ring, GRA Certified 925 Silver

This is the oval at its most wearable size. At 4x6mm the stone sits around half a carat, which is small enough to clear a glove and a coat pocket but still long enough to read as a proper centre stone. Oval works because the shape is elongated rather than round, so more of the stone stays visible on the surface of the finger and less of it is buried in depth. The length also draws the eye along the hand and narrows the look of the finger.

The stone is D colour, VVS1 moissanite and arrives GRA certified. D colour means it is graded colourless, so the stone throws white and coloured light rather than a yellow cast, and VVS1 describes clarity you will not see into with the naked eye. Grade matters even at this modest size, because a small stone sits close to the skin and any warmth in the body of the stone shows quickly. The certificate documents both.

Five sizes are offered, 5 through 9, so most hands are covered without alteration. Three finishes sit on the s925 sterling silver band, each plated in 18k. White gold is the usual choice for a colourless stone because nothing competes with it. Yellow gold introduces warmth at the shank and makes the stone read brighter by contrast. Rose gold is the gentlest of the three and suits a warmer wardrobe.
