Gemstone care
Natural and synthetic stones need TLC. Here are
some tips for extending the life and lustre of your
stones:
• Clean stones with warm, soapy water.
• Dry stones thoroughly with a soft towel.
• Some stones can be cleaned in an ultra- sonic
cleaner; a few can be permanently damaged if
cleaned in one (amber, coral, lapis, opal, pearl
and turquoise for example among a few.
(we recommend NOT using ultrasonic cleaners)
• Rub gems with a smooth, soft cloth to remove
fingerprints and keep them shiny.  
• Store stones away from intense heat and light.
