|These inside out black diamond hoop earrings combine the classic look of a diamond hoop earring with black diamonds to create a pair edgy, trendy everyday hoops! The round brilliant black diamond content is 1/4 carat, and these diamond hoop earrings are approximately the diameter of a penny, 18mm. These black diamond hoops are an every day wear size. While natural untreated black diamonds do exist, they are extremely rare. Buy.com sells only heat treated black diamonds, treated with the High Pressure Heat Treatment (HPHT) method. In HPHT treatment, white included poor quality diamonds are heated to approximately 1260 degrees Fahrenheit for a specific length of time, in a reducing atmosphere, meaning under the conditions of very little oxygen, and the unpleasant white and included diamonds become black. Buy.com does not sell irradiated black diamonds. HPHT treatment is completely safe, and produces gem quality black diamonds that can be worn an enjoyed for many, many years.|

These small earrings appear to be made well, but they also look very fragile and you would need a magnifying glass to see "diamonds". While I wasn't expecting the Hope diamond, I was expecting diamond pieces that were at least visible without the use of magnification. The "diamonds" are so small they like like tiny holes in the earring. While paying $70 for these less than flattering earrings is way too much, the list price is astronomical for the quality of the earrings.
