Bobruvka, Ždár nad Sázavou District, Vysocina Region, Czech Republic

9.3 x 6.1 x 5.7 cm

A Smoky Quartz crystal with multiple overgrowths of milky and transparent Quartz. In other words, a scepter crystal. This specimen has a glass-like lustre. The jagged termination of this crystal is due to dissolution caused by changes in the geological environment (rising temperatures, aggressive solutions, increasing pressure).

This location is a formidable place to dig at as the Mountain does not give up its treasures easily. This specimen was found in late 2010.

Anahi Mine, La Gaiba Mining District, Ángel Sandoval Province, Santa Cruz, Bolivia

6.6 x 2.9 x 2.3 cm

A natural, bi-color purple and yellow Ametrine crystal. This specimen shows true natural yellow Citrine, which is rare in nature. This specimen has good internal clarity. This crystal's unusual form is the result of hydrothermal etching while in situ. Ametrine is a combination of natural purple and yellow Quartz (Amethyst + Citrine). The color regions form on opposing rhombohedral faces of the Quartz in the shape of triangular sections. When the Ametrine crystals are viewed down the "c" axis, you can see the classic "pinwheel" or "radiation" pattern. For years a large percentage of this material was sent to Brazil for lapidary treatment. These pieces left the factories with stickers attached that said "Product of Brazil" on them leading to the misconception that the material originated in Brazil. In response, the local Bolivian miners started calling Ametrine "Bolivianite" and declared it the national gemstone of their home country.
