I think I've finally found a diamond on whiteflash to get my gf. I've reserved it and have to get back to them on Monday. It has one crystal inclusion. As per the pictures, there's also a white spec at the 10/11 o'clock position, but I asked them and they said it's just dust. Does that sound right? This also rates a 1.2 on HCA. I think i found a winner.
