Minor Gems

Minor GemsThe stones represented in the accompanying colored plate have, for the most part, but limited use, either because of their local occurrence or their lack of special gem qualities. Three of them are peculiar to the United States, and deserve on that account, perhaps, to be better known and more widely used by our people. These are variscite, chlorastrolite, and thomsonite.
