Keeping it bright

Put jewellery on last — after perfume, hairspray and lotion, all of which attack plating. Take it off before swimming; chlorine is the fastest way to dull rhodium. Showering in it is fine occasionally and unwise as a routine.

Warm water, a drop of unscented washing-up liquid, a soft toothbrush behind the stone where the film builds up. Dry with a lint-free cloth. Never use a silver-polishing cloth or dip — they are abrasives designed to strip tarnish, and they will strip rhodium with it.

Dry, dark, separate. Moissanite is a 9.25 on Mohs, which means your stones will happily scratch every other piece in the box. Keep them in the pouch they arrived in.

All rhodium wears through eventually, usually first on the underside of a ring band. Send it back and we re-plate it free, for as long as the piece is yours. See The Circle.

We list US sizes 5 to 9. To measure at home: wrap a strip of paper around the base of the finger, mark where it overlaps, and measure the length in millimetres.

US 5	49.3 mm circumference
US 6	51.9 mm
US 7	54.4 mm
US 8	57.0 mm
US 9	59.5 mm

Measure at the end of the day, when fingers are at their largest. If you are between sizes, go up — and remember the first resize is free.

16" sits at the base of the neck, 18" just below the collarbone (the most ordered), 20" at the top of the sternum and layers well over the 16". Bracelets: 16cm fits a slim wrist, 18cm is standard, 20cm wears loose on purpose.
