Treatments and Care

Gemstone Treatments:
Gemstone Treatment Care
Sapphire Heat (unless specified to be unheated in the product details) Sapphires are easy to care for at home. Sapphires can be cleaned using any cleaner that is specifically designed for use with jewelry, or, if set in gold or platinum, with warm water and a splash of grease removing dish soap or cleaning detergent. Avoid using any products that include moisturizers, abrasives or anti-static agents, as they will leave a residue and scratch the metal. Scrub gently with a soft bristle toothbrush and rinse well. Dry with a soft cloth. For deeper cleaning, allow the piece to soak for 10 to 20 minutes in a mixture of warm water and a small amount of grease removing soap, and then follow the remaining steps of the above procedure. This process should not be used for sapphires set in silver as many detergents can react poorly with silver.
Ruby Heat (unless specified to be unheated in the product details) Rubies are easy to care for at home. Rubies can be cleaned using any cleaner that is specifically designed for use with jewelry, or, if set in gold or platinum, with warm water and a splash of grease removing dish or cleaning detergent. Avoid using any products that include moisturizers, abrasives or anti-static agents, as they will leave a residue and scratch the metal. Scrub gently with a soft bristle toothbrush and rinse well. Dry with a soft cloth. For deeper cleaning, allow the piece to soak for 10 to 20 minutes in a mixture of warm water and a small amount of grease removing soap, and then follow the remaining steps of the above procedure. This process should not be used for rubies set in silver as many detergents can react poorly with silver.
Emerald Infusion - Oiling Due to their brittleness, emeralds must be handled gently. Cleaning techniques that involve chemicals, high heat or steam are not advised, as they can cause the gem to break or the oil filler to dissipate. Special care should be taken when wearing emerald jewelry given emeralds are prone to fracture if roughly handled. This gemstone can be taken to a Brilliant Earth showroom to be cleaned.
