Vintage Swarovski Crystal, 40ss Tourmaline AB. These Swarovski crystal stones are set in a high-quality 4-pronged, open back settings - photos show crystals set in silver and gold plated settings. There are 4 holes in the setting, 2 on 2 sides. 40ss is approximately 8.51 mm to 8.63 mm
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: Some oils and lotions can erode the foil backing on the crystal. If in doubt, whether something will hurt the foil, take the ring (or other piece of jewelry) off.

❤️”Have ordered two gold wire rings back to back and am delighted with both! I alternate them and get constant compliments.
The rings are sized correctly and the great workmanship deserves mentioning! I’m very happy with both treasures!
Package came quickly and I was updated when the order was received, made and shipped all of which took 3-4 days. Would give her my business again for sure!“
