Wound up deciding not to do the garnets, though I sighed when I set them in the "not at this time" list. But they would have been a bit more complex of a project, and getting enough information about their composition to be able to tell their source would mean either doing composition maps or at least a series of analysis spots across the whole garnet, which would likely be a bit more than the museums really want on jewelry.
