new year 2021

Some of the world's clearest and most perfect Quartz has come from the finds in the ridge above the Peñas Blancas Emerald Mines in Boyacá, Colombia. This is an incredibly clean highly lustrous example, one of a small carefully selected suite we obtained at the mine. The luster is brilliant and almost impossible to see in a photograph. This zone has recently produced a lot of good to fine Quartz but very close exam finds that there are very few truly perfect examples, nearly all have at least some chips or rough spots on terminations. This is a remarkably limpid and flawless piece that can act as a prism to make rainbows. Nothing like the average material from here, this is textbook perfect. As is sometimes seen at this locale this piece has some extra faces in corners adding some nice modifications.

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.

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.
