Pearl Care

Pearls are soft and porous. They need to go on last, come off first, and be stored apart from everything else.

Pearl Restoration

Lightly polishing away a damaged outer nacre layer to reveal fresh nacre beneath. Only possible on thick-nacre pearls.

Peeling

Nacre lifting or flaking away from a pearl, exposing the bead beneath. Terminal, and caused by thin nacre or chemical damage.

Re-plating

Restoring a worn plated finish. Routine maintenance for white gold and plated pieces, not a repair.

Restringing

Replacing the thread a strand is built on. Routine maintenance, not repair, and overdue on most pearl necklaces.

Steam Cleaning

Cleaning with a jet of high-pressure steam. Fast and effective on hard stones, unsafe for pearls and soft gems.

Storage

Where and how a piece is kept between wears. More damage happens in the box than on the body.

Tarnish

The dark film that forms on silver as it reacts with sulphur in the air. Surface only, and it polishes off.

Tooth Test

Rub a pearl gently against the edge of a tooth. Real nacre feels faintly gritty; an imitation feels glassy smooth.

Ultrasonic Cleaner

A tank that cleans by vibrating a liquid at high frequency. Excellent for diamonds and destructive to pearls.

Yellowing

The gradual browning of old pearls as the protein binding the nacre oxidises. Usually irreversible.
