These beautiful 1/4 carat black diamond hoop earrings will be a staple of your wardrobe. Natural black diamonds are rare. SuperJeweler sells only heat treated black diamonds, treated with the High Pressure Heat Treatment (HPHT) method. In HPHT treatment, poor quality diamonds are heated to approximately 1260 degrees, and the diamonds become black. HPHT treatment is completely safe. Black diamonds from SuperJeweler have varying numbers of facets from 0 to 16 are not considered gem quality diamonds.
