They are all surface enhanced designer stones.
Surface of the stone, either Bottom (Pavilion ) or surace of the white stones ( Topaz or CZ ) is treated by a thin-film optical treatment. This method is known within the technical industry as Physical Vapor Deposition (PVD). The PVD method is unique: utilizing various minerals, oxygen and high vacuum, and is considered to be environmentally "green" since no radiation or harsh chemicals are utilized.
The method of treatment is patented by the coating company in USA, the patent number is 5,853,826.
The thin film treatment applied to gemstones is durable and hard. The treated layer is only microns in thickness. If the wearer utilizes care, the enhancement will last the life of the jewelry setting.
The difficulty of making jewelry with mystic color stones is higher than using ordinary stones like regular cz or genuine amethyst, because all these mystic color stones cannot go into the rhodium bath, that means we have to set those stones onto the rhodium plated jewelry, it is our high craftsmanship overcoming this difficulty.
To have a secure and long lasting coating, stones ( white topaz or white cz ) of very good quality have to be used.
To clean the mystic color stone, please do not use any abrasives, acids, or immersed in an ultrasonic cleaner. Soapy water is good enough.
Mystic Color is the trend forever, stay tune for more new color !
