FQ46G6: Quartz after Octahedral Fluorite

In a first view, as a Quartz, it looks rare. And it is rare, because it has the form of octahedral Fluorite, previously existing and substituted by the Quartz. More curious is to observe that the surface is cryptocrystalline Quartz (Chalcedony) but the core of the octahedron, where Fluorite primarily was, is hollow and consists of little geodes covered by Quartz crystals.

Price: [SOLD]

TG96AI5: Quartz

Druse of Quartz crystals on a chalcedony matrix. They are very clear and colorless, very bright, rich in faces and have the typical shape that relates to the name of the mine. An extraordinary sample, very fine and carefully preserved, from a classic French locality for Quartz. We’ll send to the buyer the label from the Jean-Pierre Gilian collection.
La Gardette Mine, Brides gallery, La Gardette mining area, Villard-Notre-Dame, Le Bourg d'Oisans, Grenoble, Isère, Auvergne-Rhône-Alpes France (2015)

NK13T9: Chrysocolla

This is a Spanish novelty because in the Los Amigos Mine Chrysocolla wasn't mentioned before. We should also mention that the appearance of this Chrysocolla is very attractive as it isn’t just a crust as usual but it has nice forms covering what seem to be crystals of Quartz and probably Chalcedony. These nice forms together with their great color, generate what is, in our opinion, the best Chrysocolla found in Spain and nearly as fine as the nicer ones from other countries.
As usual when we offer unusual things like this, we will send a copy of the analysis to the customer.

EV98D1: Fluorite with Quartz

A special specimen. The single ball with reddish color is very attractive, but also its matrix is different from the others we have seen: it is a kind of microcrystalline Quartz similar to a Chalcedony recovered by Opal. Plus a few small well-crystallized Quartz crystals are deposited on the ball. Funny and interesting in mineralogical terms!.
The specimen's photo has been reviewed and published in the magazine ‘Rocks & Minerals’ on page 299 in the volume 83, number 4 and in the magazine ‘Lapis’ on page 18, volume 35, number 10, Octubre 2010.

ED97AE3: Brochantite with Chrysocolla and Atacamite

A novelty at Munich 2016. Until now a poorly known mine, the Brochantite forms sprays of finely acicular crystals with a very intense silky luster and a very vivid color. They are with darker small Atacamite crystals and are on a Quartz (variety chalcedony) matrix coated by botryoidal Chrysocolla growths. Very aesthetic for the contrast of the Brochantite with the Chrysocolla.
This sample has been photographed and published as a novelty in Munich 2016 in the magazine Le Règne Minéral number 132, page 43, the magazine ‘Mineralogical Record’ on page 148 in the volume 48, number 1 (January-February 2017) and in the magazine ‘Mineral Up’ on page 54 of the 2014/02 edition.
Los Azules Mine, Quebrada San Miguel, Copiapó Province, Atacama Region Chile (11-12/2015)
