JH20876 Terlingua Type Calcite Rhomb, Challenger Cave, Mexico

Description

Up for bid is a color changing Calcite Rhomb from the Challenger Cave in Mexico. This material is similar to the famous Calcite from Terlingua Texas. It glows bright Blue-Violet under SW UV (first picture), bright Pink under LW light (second picture), and has a very bright and long lasting phosphorescence. You can even see the fluorescence and phosphorescence in a brightly lit room!
This material is mined as huge crystals up to 1.5 meters long. Calcite has perfect cleavage in all three axis so when these large crystals are broken up, they produce miniature versions of themselves. This material has not been available for many years.

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.
