Nice crystals :) Why are you calling them star garnets?
Welcome to the forum.

They're star garnets because when they're cut in cabs, if done at the correct orientation, they show a "star" in the finish. I think idaho is the only place that has them, or had them. They're Idaho's State Gem.

I guess I'm not being clear ;) What characteristics does the raw material demonstrate, without cutting them, that allows one to determine if the garnet will have asterisk patterns aside from the locality where they are found?

DDancer,

The only difference I can find in the rough is the Star Garnets appear more opaque due the inclusions of Rutile. Dark, nearly brown in color. Most likely a very similar comparison of say Ruby and Star Ruby. -Luke

Under a strong light one can see the start effect, often in addition to a fluid. That's how we cutters orient star-showing gems.

I've cut small garnets from Mozambique that had cat's eye effect. Those star garnets from Idaho can be worth a few dollars.
