Frequently asked questions

How do I measure my ring size at home?

Wrap a strip of paper around the base of the finger, mark where it overlaps, and measure the length in millimetres. Match the circumference to a ring size chart, and measure at the end of the day when fingers are largest.

How often should I clean my jewelry?

Wipe silver and diamond pieces after each wear and do a deeper clean monthly, or more often in summer and after heavy product use.

Can I shower or swim with 925 silver?

Occasionally is fine, but chlorine and salt accelerate tarnish and plating wear. Remove jewelry for pools, sea water and long showers.
