As all of my Artwear is made with soft wire it is best to use caution when wearing sweaters or any other material that may catch on the wire and possibly pull the piece out of shape. To clean use a Jewelry Cleaning Cloth. Do not use liquid cleaner at it can damage your stone. Store your pendant in the bag it came in for protection.
What is the coating on my Druzy gemstones? The process is called Particle Vapor deposition or PVD. While in a special vacum chamber the stones and the metals are manipulated with oxygen and various gasses to deposit the metals permanently onto the surface of the stones. This can also be done with other metals such as platinium or gold, and the colors can be controlled to create many different shades. The coating is quite durable, and with reasonable care should last a lifetime. I purchase them from a USA distributor.
