How to Clean and Care for Sapphire Jewellery

A sapphire is one of the few possessions genuinely built to outlast you — at 9 on the Mohs scale, only diamond is harder. But hardness is not invincibility, and settings need more care than stones. Here is how we care for sapphires in our own workshop.

The routine clean (all you usually need)

Warm water, a drop of mild dish soap, and a soft toothbrush. Soak for a few minutes, brush gently behind the stone where skin oils and sunscreen collect, rinse, and pat dry with a lint-free cloth. Oils are the main enemy of sparkle — they film the pavilion and dull the stone's fire. A monthly two-minute clean keeps a sapphire looking freshly set.

What to avoid

Knocks along the girdle. Hard, yes — but a sharp edge-on blow can chip any gem. Remove rings for the gym, gardening and moving day.

Harsh chemicals. Chlorine and strong cleaners will not harm the sapphire, but they attack gold alloys and can loosen claws over time. Jewellery goes on after perfume and lotion, not before.

Ultrasonic caution. Untreated and heat-treated sapphires are generally safe in ultrasonic cleaners — but fracture-filled or heavily included stones are not, and settings can loosen. If in doubt, warm soapy water risks nothing.

Check your settings yearly

Claws wear; stones do not. Once a year, have the setting inspected — we do this for our clients as part of our lifetime service, and any jeweller can check tension in minutes. A thirty-second inspection prevents the only real tragedy: a perfect stone lost from a tired claw.

Storage

Sapphires scratch softer gems — including gold and opals. Store pieces separately in soft pouches; never let a sapphire ring tumble loose with an opal or pearl.
