Moissanite Solitaire Ring, 0.5ct to 10ct, VVS1 Certified

A solitaire ring is one stone and a simple band, which makes it the easiest style to get right and the hardest to disguise a weak stone in. There is nothing else for the eye to settle on, so grade matters more here than on a ring with accent stones. The plain band also does the quiet job of keeping the ring comfortable, easy to clean and simple to stack under or beside other bands later.

The stones are VVS1 clarity moissanite and each ring ships with its certificate. VVS1 means any inclusion is invisible without strong magnification, which matters most as the stone gets bigger and the flaws get easier to find. Moissanite measures 9.25 on the Mohs scale against diamond's 10, and its refractive index of about 2.65 is higher than diamond's 2.42, so the fire is stronger. It is a real stone with real hardness, not glass.

The weight range is very wide, from 0.5ct to 10ct, so decide how the ring will be worn. The 0.5ct and 1ct suit daily wear, work and gloves. The 2ct is the balanced choice with clear presence. The 3ct and 5ct are statement rings that suit a longer finger. The 10ct is a showpiece and feels heavy on the hand. Ring sizes run from US 4 through 10 in half steps, in 925 sterling silver.
