BLACK ONYX EARRINGS(STUDS).We haven`t used Black Onyx in many of our designs before, but regular requests have resulted in some new pieces. This funky, original design features eight (8) 5mm x 4mm facetted Onyx gemstones in each stud. All the stones move separately, creating a lovely effect. Black Onyx is said to help people to forget about their past relationships and bring people in tune with the present. Black onyx symbolize purity. According to ancient legend, the dark color of the stone is due to absorb much negative energy. These earrings weight 10.5g, they are5.4cm long and 2.8cm wide.
