6mm Moissanite Cuban Chain in 925 Sterling Silver

A Cuban link is thick, flat and tightly interlocked, so it sits smoothly against the skin and has real weight. This 6mm version is set with moissanite and built in 925 sterling silver, which puts it at the quality end of what an iced chain can be. Six millimetres is the sensible width. It is wide enough to be seen on a bracelet or a necklace, but still comfortable under a sleeve or a shirt collar through a full day.

The stones are moissanite, silicon carbide with a refractive index of about 2.65 against diamond's 2.42, so the chain throws more coloured flash. A chain gets handled more than any other piece, rubbed by clothes, bags and seatbelts, so hardness is the practical reason to choose it. At 9.25 on the Mohs scale it resists scratching far better than cubic zirconia or glass, and the sterling silver underneath will not tarnish the way a brass chain does.

The listing covers both a bracelet and a necklace in one width, so decide the form first. Bracelets come in 6 inch (15cm), 7 inch (18cm) and 8 inch (20cm), and the right one is your wrist measurement plus about 1.5cm for a comfortable drape. Necklaces start at 16 inch (41cm), 18 inch (45cm) and 20 inch (51cm), which fall at the collarbone or just below it. Finish is silver, and the chain suits men and women equally.
