Total carat weight follows stone width and wrist length. A 2mm line on a 7-inch wrist works out to roughly 2 carats total; 3mm to around 4 carats; 4mm to 7 carats and above. Choose the width you like on your wrist and let the carat weight follow.

Sterling silver tarnishes over time by nature. Rhodium plating slows it considerably, and regular wear helps, because the natural oils on your skin keep the surface polished. If it does dull, our free lifetime refinishing brings it back.

Moissanite, in almost every case. Cubic zirconia is softer (8.5 Mohs against 9.25), clouds and scratches within months of daily wear, and has visibly less fire. CZ is cheaper; on a bracelet, which takes the most knocks of any jewellery you own, that saving does not last.

On a standard thermal pen tester, yes — moissanite conducts heat much like diamond. A dual tester that also measures electrical conductivity will correctly identify it as moissanite.

Yes, if you want the brilliance and durability of a diamond bracelet at a fraction of the price. Moissanite is harder than every common gemstone except diamond, which makes it well suited to a piece that takes daily contact. The trade-off is resale value: moissanite is bought to be worn, not held as an asset.
