Dec 2018

A perfectly etched cubic Fluorite with the unique emerald green corners of Penas Blancas. This rare zoning has now been attributed to the same Chromium that colored the world class Emeralds found just a few hundred meters lower on this mountain. This is transparent and mostly colorless like an ice cube with complex crystallized. etched surfaces on all sides. There is no damage or chipping A very fine example that is choice, complete and shows the selective color in the corners perfectly.

Late Summer 2018

The clarity and perfection of the top pieces of Penas Blancas (Colombia) Quartz are just amazing. This is a textbook perfect, clean and very lustrous crystal. Hard to fully appreciate in photos, the crystal acts a prism and the striations will diffract light unlike other Quartz. We source at the mine and select a very small percentage of single prisms, offering only the most perfect of each find. The recent finds at Penas represent a great value for price to quality that is rare in the mineral world.

Late Summer 2018

From the incredible finds at Penas Blancas come some of the worlds clearest Quartz. Remarkable optical-grade clarity, fine condition and with a few edge modifications;(extra faces). The striations are very distinct and add a prismatic effect from some angles. We have had been to visit these prospects and mines, selected top specimens and are pleased to offer these fantastic prisms. Much more transparent in person.

Spring 2017

A really attractive and different sort of Fluorite. The Emerald mining area at Penas Blancas has produced a very small number of highly etched Fluorites over the past 2 decades. Most are cubes a a few are Octahedra, most are colorless and a few are pink. These are usually very deeply etched and re-crystallized and sometime have emerald green globs in the center or corner of the crystal. This is a pink corner of an octrahedron that is naturally etched and has a nice green spot in the center. Gemmy enough to be faceted, this unusual habit is I belive only in a small prospect about 250 meters higher above than the Penas Blancas Emerald zone. A very good example of a rare form.
