The alluring blue hues of kyanite need to be gently cared for to keep their charm. It should be treated carefully because of its fluctuating hardness, which ranges from 4.5 to 7. Kyanite gemstone can be harmed by exposure to harsh chemicals, high temperatures, and ultrasonic cleaners. Kyanite jewelry should be cleaned with a gentle cloth and a little soapy water, then well dried.

Store kyanite separately to avoid scratches or chips from tougher stones because it is brittle. Kyanite stone will retain its brilliant blue tones and enduring beauty with the right maintenance, whether it is set in jewelry or left as a loose crystal.
