Mineral Matters #444
Thanks Steve I was puzzled by your comment.A good buy in that case.
I know what a keystone is but what is your context relevant to price??
Sorry Jeff. I should have explained. Keystone is a pricing structure used in the US. Keystone = 50% of marked price. So I paid US$20 for the specimen. Incidentally, Double Keystone is 75% off.
