TREATMENT & CARE
Treatments & care
Treatments & identification
Resin impregnation and dyeing may be encountered. Appearance alone can be insufficient, so examination is used to assess treatment.
Everyday care
Avoid acids and high heat and clean gently. Avoid ultrasonic or steam cleaning when treatment information is unknown.
Cleaning depends on treatment, inclusions and mounting. If a stone's condition is unknown, ask your jeweler or a gem specialist before cleaning.
