Up for bid is a large specimen with Hackmanite Crystals, Phlogopite Crystals and I think Calcite from the Koksha Valley in Afghanistan. The Hackmanite crystals are on the left of the specimen and fluoresce White SW (First Picture),White MW (Second Picture) and Orange LW (Third Picture). Note that the daylight color of the Hackmanite is Bluish-Violet so the White from the Fluorescence is brings out this color. The Hackmanite is also Phosphorescent (Fourth Picture) and Tenebrescent (Fifth Picture).

The Phlogopite crystals on the right of the specimen fluoresce Straw-Yellow under SW (First Picture). There is another mineral that fluoresces Violet MW (Second Picture) that I think is Calcite.

First picture is under SW UV. Second picture is under MW UV. Third picture is under LW UV. Fourth Picture is Phosphorescence. (no UV present) Fifth picture shows Tenebrescence (Color change after exposure to SW UV). Sixth picture is under White Light. (Before UV exposure)

Domestic Shipping
For domestic shipping I generally use Fed Exp Ground for heavier and more expensive items, and US Postal Service Priority Mail for lighter and less expensive items. Both services have door to door tracking and full insurance. If you have a shipping preference please let me know. If the shipping service I use costs less than eBay charges, I will refund any excess. I only charge actual shipping costs with no extra charges for packing or shipping materials and will gladly combine shipments. If the combined shipping doesn�t work for some reason, I will refund any excess shipping.

International Shipping
I use US Postal Service Priority mail for all international shipments. Please note that due to a lack of international flights, many overseas shipments are going by boat instead of air. This can add a month or more to delivery times. Purchase at your own risk.
