Vintage Tourmaline AB, also known as Aurora Borealis (AB), features a special iridescent coating that creates a mesmerizing, rainbow-like effect reminiscent of the Northern Lights. This coating, developed by Swarovski in 1956 in collaboration with Christian Dior, reflects light in a captivating way, producing a spectrum of colors including blues, greens, pinks, yellows, and purples. The specific hues and their intensity can vary depending on the base color of the tourmaline stone, in this case, Tourmaline Green, and the angle of the light hitting it. The AB coating on vintage tourmaline AB rhinestones is designed to enhance the sparkle and create a multifaceted, color-shifting appearance on the rhinestone surface.

A small note about foil-backed stones: Swarovski’s sew-ons are excellent quality; I have at least 3 I rarely take off. However, there are chemicals and some oils and lotions that can eat at the foil on the back of the crystal. If in doubt, whether something will hurt the foil, take the ring (or other piece of jewelry off).
thanks for stopping by - hope to see ya again soon.....
