[QUOTE="Wally69, post: 502338, member: 1916"] Yummy yellow sapphire there Ray :inlove: I think it is all about the silk when it comes to stars, not sure if you have come across a grey silky stone yet, they are probably the best natural stones to educate yourself. This is lifted from the www. But it shows the silky grey quite well.

With yours I would be cleaning it up on a lap to remove obvious faults and inspecting the silk closely. Can it be avoided, can it be heat treated would be the first questions I would ask.......Then could it be cabbed, and if so what orientation may produce a star. This image comes from an ancient text, but is quite enlightening.
