Caring for Your Gemstone Jewelry
As a first step, let your jewelry piece soak for a few moments in a solution of warm water and mild detergent. Never use a cleaning solution that contain ammonia or chemicals as it can damage sensitive gems.
Use a soft brush to gently scrub your jewelry. Toothbrushes with bristles designated "soft" or "extra-soft" are fine for cleaning most jewelry stones at home. However, avoid using any brush with hard, inflexible bristles or any toothbrush with bristles designated "medium" or "firm/hard."
When you've finished scrubbing, dip the jewelry piece back into the solution for one last wetting. Then rinse in warm running water, preferably about the same temperature as your solution. Radical temperature changes are dangerous and should be avoided.
Shake or blow on the jewelry piece to remove excess liquid, then gently polish with a soft lint-free cloth or chamois.
