Certified Moissanite Bracelet, 14cm to 21cm Adjustable

This is the lighter of the adjustable bracelets, built so the stone line sits on top of the wrist and the plain chain carries round the back. That construction matters for comfort: there is nothing hard pressing against the underside of the wrist when you rest your arm on a desk or hold a steering wheel, and the chain can take the adjustment without the stone section bunching. The slider runs the full 14cm to 21cm range.

The stones are certified moissanite. Certification is worth more on a bracelet than people assume, because a bracelet is the piece people look at closely while you are talking to them, held at conversational distance rather than seen across a room. Moissanite reads close to white diamond but with more fire, since its refractive index of about 2.65 bends light harder than a diamond's 2.42, and at 9.25 Mohs it survives the knocks a wrist takes.

One length covers 14cm to 21cm, so sizing is a matter of where you set the slider rather than which variant you order. Set it close to your measured wrist for a bracelet that stays put and keeps the stones facing up. Add about 1.5cm if you prefer it to move. Three finishes are offered on 925 sterling silver plated 14k. Silver is the neutral choice, gold is the warmest, and rose gold falls in between the two.
