i bought these earrings on ebay. I love hematite...the flash and the mysterious look of the stone...and, these were made to look like solitaires but since flat backed they sit right on the ear. The screwbacks were charming but i feared loss of an earring and they pinched a bit at times. I took them yesterday and had 14kt gold (for my sensitive lobes) posts put on and the screw back removed. He used a laser to keep all safe. I have extra large gold backs on them to hold them in place. They came out great. Here are before and after shots.
