Gemstone faceting a 2 ct sapphire.

Im cutting another montana sapphire in this video, this stone is old stock from the spokane bar mine.
I used a 600 grit crystalite lap for the rough cutting and 3k diamond on a zinc lap for prepolishing followed by 8k on copper then the final polish is 60k diamond on a batt tin lap.
I want to clarify something i mentioned in the video concerning the index markings on my machine, this is an older v2 model ultra tec machine and the index gears may or may not be marked this way now.
Also sorry the music is louder than usual, i used the same volume settings as i normally do but it did turn out louder than i would have liked.
I sell my gemstones and other finished jewelry in my etsy store : gemsbymbk, here is a link

Thanks for watching.
