Round Moissanite Band Ring, 3mm to 5mm in 925 Silver

Band width is the decision that matters most on a ring like this, because it changes both the look and the way the ring wears. A 3mm band sits low and close, so it slides under a knuckle easily and stacks with other rings. A 5mm band covers more of the finger, stands taller off the skin and reads as a single statement piece on its own. Round cut stones run along the face of the band, keeping the line even all the way across.

The stones are round brilliant moissanite. The round brilliant is the most efficient cut for returning light straight back at the viewer, which is why it stays bright even at the small sizes used across a band. Moissanite suits this job because it is hard, 9.25 on the Mohs scale, and a band takes constant abrasion from whatever your hands touch. Its refractive index of roughly 2.65 is higher than diamond at 2.42, so it flashes with coloured fire rather than plain white light.

Choose 3mm for an everyday or stacking ring, 4mm as the middle option that works alone or in a pair, and 5mm when you want the ring to be the only thing on the hand. Sizes start at 4 and climb in half steps, so the range covers smaller and larger fingers alike. The 925 sterling silver band is plated in 18k and offered in white gold, yellow gold or rose gold.
