Preservation

Gemstone Care Guide

Storage

Store each gem in a separate soft pouch or lined box to prevent scratches. Keep away from direct sunlight for light-sensitive stones like Alexandrite.

Cleaning

Use warm water, mild soap, and a soft brush. Avoid ultrasonic cleaners for fragile or included stones such as Jeremejevite and Poudretteite.

Handling

Handle by the girdle, not the table. Some rare gems are brittle; avoid sudden temperature changes and harsh chemicals.

Insurance

Keep certificates with updated appraisals. Astra can connect you with a certified appraiser for ongoing coverage.
