6mm Miami Cuban Bracelet, Solid 925 Silver, GRA

A Miami Cuban link is a curb chain with flattened, tightly packed links, so it lies smooth against the wrist instead of bunching or flipping over. At 6mm it is the width that works for most people, wide enough to read as a proper chain and slim enough to slide under a shirt cuff. The links are solid 925 sterling silver rather than hollow tube, which gives the bracelet real weight and means it will not feel thin when it moves.

The iced out surface is moissanite, and the piece is GRA certified, so the stones are documented rather than taken on trust. Moissanite is silicon carbide with a refractive index of about 2.65, higher than diamond's 2.42, so it throws more coloured flash under moving light. It rates 9.25 on the Mohs scale against diamond's 10. That hardness matters on a bracelet, because wrists meet desks, door frames and steering wheels every day, and softer stones lose their edges fast.

Length is the one choice to get right. Six sizes run from 6 inches to 8.5 inches in half inch steps. Measure around the wrist bone, then add about half an inch for a close fit or a full inch for a relaxed drape. The 6 to 7 inch sizes suit most women, and 7.5 to 8.5 inches cover most men. There is a single silver finish, so the decision is only about fit, and solid silver means the chain keeps its shape for years.
