Emerald AB 39ss Swarovski Vintage Crystal, 2 or 4 Pcs Art 1110, with SP or GP Settings

Emerald AB 39ss Swarovski Vintage Crystal, 2 or 4 Pcs Art 1110 Channel cut, with SP or GP Settings. These Swarovski crystal stones are set in a high-quality, 4-pronged, open back, and are available in your choice of silver or gold-plated. Also, your choice of the AB finish facing up, or the solid color facing up.

Vintage Swarovski rhinestone in the color Emerald AB has a base of rich, medium to dark emerald green, which is then overlaid with the iridescent Aurora Borealis (AB) coating. This special coating gives the rhinestone a shimmering, rainbow-like effect, causing it to reflect additional colors as it catches the light. 
The base color is a solid, transparent emerald green that resembles the May birthstone. The AB finish, named for the "Aurora Borealis" (Northern Lights), was developed by Swarovski in 1956 in collaboration with designer Christian Dior. It is a thin, metallic coating that is applied to the surface of the crystal to increase its brilliance.
The AB coating on the emerald green base causes the stone to shimmer with a mix of colors, including hints of yellow, pink, and blue. When the light shifts, so does the sparkle, giving the crystal a multi-dimensional glow. The effect of the AB coating on a deep base like emerald is to bring the base color to life with added movement and depth. The final look is more dynamic and sparkling than a non-AB crystal of the same color.
The vintage Swarovski rhinestone article number 1110 is the specific article number for this shape, which is a channel-cut round rhinestone with the same cut on both sides, produced in the 1960s and earlier. A channel-cut stone is designed to sit securely inside a metal setting, or "channel," that holds it in place. These stones are also sometimes found in settings with loops for use as connectors in jewelry. These crystals are unfoiled, meaning they do not have a silver-colored metallic layer on the back. This allows light to pass through the stone, making it transparent and giving it a different visual effect than a foiled rhinestone.
The AB finish is only on one side, creating a stunning visual effect when many are used together. Like other vintage Swarovski components, these rhinestones are valued for their high-quality, precision machine-cut facets that are designed to maximize sparkle and brilliance

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).
