[QUOTE="Wally69, post: 253565, member: 1916"] Thanks Lefty I used a type metal lap with 3000 grit to cut the facets and 100000 to finish. Was surprised how hard the stone was given the folk-law of being soft, the preforming was reasonably fast but slower than I expected to the point that I had good control on the rate of cut. As the stone is small and I still have my L-plates on the gemmasta, I decided to try cutting a facet on the 3000 on an old lap without recharging it and it worked a treat for control of the cut so I kept with it. iPad photo just don't do it justice, but from my end, the variance in appearance in different lights has made this exercise a lot of fun. Currently thinking about how I go about the crown, faceting will be quick and easy but am considering cabbing it, something I havn't done yet. [/QUOTE]
