This thumbnail is a superb example from the famous phosphate deposits of the Yukon. 1.6 cm long, the major crystal has the beautiful deep blue color that is so sought after; plus good form and superb luster. Minor golden siderites provide accent. It is even better in person. Some of you will look at this and think I am crazy on the price, based on what larger pieces cost for more coverage and more size, but I simply haven't seen a THUMBNAIL so perfetly balanced with such a fine isolated crystal before, and it is WORTH the price I assure you, for somebody who wants that extra bit of quality and isolation to their thumbnail gem XL. I valued it highly myself in purchasing this collection.
