About South Sea pearls
The world’s rarest and most valuable cultured pearls. Every AUTORE pearl comes from our own farms in Australia and Indonesia, spends two years within its host oyster, and is graded by the AUTORE Five S’s™ — Shine, Surface, Shade, Shape and Size. Read the guide
Jewellery care
Pearls are made to be worn, and are the last thing you put on: apply perfume, hairspray and make-up first. After wearing, wipe them gently with a soft, damp cloth and store them separately in a soft pouch. Avoid water, chemicals and ultrasonic cleaners. Full care guide

How to measure
String or paper strip
Wrap a thin strip of paper or string snugly around the base of the finger you’ll wear the ring on. Mark where the end overlaps, lay it flat against a ruler, and enter the length in circumference mode.
An existing ring
Lay a ring that already fits flat and measure straight across the inside, edge to edge. Enter that inner diameter in diameter mode.

Sizing tips
- Measure at the end of the day, when fingers are at their largest — avoid measuring when cold.
- Millimetres give the most accurate result: ring sizes are only about 0.2mm apart in diameter.
- Wider bands (6mm+) fit more snugly — consider sizing up half a size.
- If you’re between two sizes, we recommend sizing up.
- Measure the finger you’ll actually wear the ring on — dominant hands are often slightly larger.
