Vintage Swarovski Crystal, 40ss Montana Sapphire 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
Swarovski's Montana Sapphire AB color is characterized by a deep, iridescent blue, sometimes described as a dark or navy blue with an Aurora Borealis (AB) coating. The AB coating creates an iridescent shimmer that catches and reflects light, adding an iridescent sheen to the crystal that reflects multiple colors depending on the angle of light, in rainbow hues, particularly in shades of pink and purple. This effect can make the Montana Sapphire AB appear more sparkly and dynamic compared to a standard Montana Sapphire crystal without the AB finish.

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.

❤️”Another BEAUTIFUL ring from Bobbi! My husband got me my first for Mother's Day last year, our son's birthstones. This ring is a "Treat yo self" and also my mom's birthstone. I can attest to the quality. I have worn my first ring close to every day for a year and it's just as beautiful as the day I got it! The quality is top notch and her skill is mind boggling!”
