Stupid ebay. Why didn't I leave my initial bid and walk away? Anyway, I won my auction, and here's the stone I got. It feels like I spent an hour lapping it with SiC powder, but it was probably more like 30 minutes. After it cleaned up a little I drew on it with a marker and the lines disappeared simultaneously (and slowly!). So there was nothing to indicate to me that there were any high/low spots.
But everything I read about these says you have to lap them for hours and hours. So, do you gents have any insight to share? The two little marks toward the end with the chip go in, the don't stick out. I think it would take days of lapping to get them out.
