Since these gems are very delicate, they can crack or chip if cleaned in an ultrasonic machine. Stones that have undergone waxing and oiling treatments to enhance their quality, like turquoise and emeralds, are more likely to dull if cleaned incorrectly.

And thorough drying is a must, especially when cleaning gems that are set in sterling silver, which can tarnish with extended exposure to moisture.
