These crystals are genuine Swarovski crystals: #1122 rivolis, #4470 cushion squares, and #5328 bicone beads, with special coatings applied by a third party. Third-party coatings include transparent and opaque coatings that enhance, change or partially cover the base crystal color.
Transparent coatings (such as Purple Haze and Mahogany) change the appearance of the item to a mixed hue, a combination of the base color and the transparent coating.
Opaque/Metallic Coatings (such as third-party Bermuda Blue, Electra and Volcano) coat the crystal in a metallic covering. This coating can be applied to the top or bottom of an item or coat the entire item.
The Ultra AB coating is incredibly vibrant and saturated with color, taking classic Swarovski crystal stones to a new level.
Third-party coatings do vary more than Swarovski's highly controlled effects, but they offer wonderful extra variety that would otherwise not be available.
