A 7x5mm oval blue apatite cat's eye with 0.30 carats of round blue sapphire and 0.02 carats of round white diamond in rhodium over sterling silver earrings measuring approximately 0.80 inches with lever backings - the gemstone earring where the optical phenomenon of the center stone does most of the visual work. Apatite cat's eye exhibits chatoyancy: a band of reflected light that appears to float across the stone's surface as the viewing angle changes, like a cat's slit pupil. Combined with blue sapphire and diamond accents, the earring delivers optical interest and genuine gemological quality. Lever backings.
