Details: You ll fall in love with the unique tension setting of this lovely pendant, which allows the central stone to dance and vibrate continuously with every movement you make. This dazzling pendant is crafted of real .925 sterling silver in a spiraling circular open shape reminiscent of the orbit of a galaxy of stars. It s accented by a high-quality gemstone at the center: gemstone weight ranges from .18 to .25 carat, depending on the gemstone, due to differences in mass of different gem types. The 7mm long knot design has 0.03 carats in total of sparkling diamond accents that frame the gemstone in the center. The pendant is suspended from a matching sterling silver 18” rope chain with a 2” extender that secures with a lobster claw clasp. The sterling silver pendant and chain are plated in rhodium, a tarnish-free and hypoallergenic metal from the platinum family of metals.
