Care & Cleaning

Cleaning

  1. Fill a small bowl with warm water and add a few drops of mild soap or a gentle jewelry cleaner.
  2. Place the topaz into the water and let it soak for 10-20 minutes. This will help to loosen any dirt or debris that may have accumulated on the surface.
  3. Use a soft-bristled brush (such as a toothbrush) to gently scrub the topaz. Be sure to pay attention to any crevices or corners where dirt may be trapped.
  4. Rinse the topaz under warm running water to remove any soap residue.
  5. Dry the topaz with a soft, clean cloth. You can also use a hair dryer on the cool setting to gently dry the stone.
Note: If your topaz has any fractures, it is best to avoid using water to clean it. Instead, you can use a soft, dry cloth to gently wipe the surface of the stone.

Care

  • Store your topaz in a soft cloth or pouch to prevent it from scratching against other jewelry or surfaces.
  • Avoid exposing your topaz to high heat or sudden temperature changes, as this can cause it to crack or fracture.
  • Avoid exposing your topaz to chemicals, such as household cleaners or hairspray, which can cause damage to the stone.
  • Take off your topaz jewelry before doing any physical activity or exercise, as it can be prone to scratches and damage.
  • If you’re not wearing your topaz jewelry, keep it away from direct sunlight and store it in a cool, dry place.
