Pre Tucson
Classic Colombian Emerald crystal on matrix. Excellent transparency, the crystal is fairly thick, glassy with basal termination. The color is a very rich green but not quite the top intense color which is of course far more expensive. Sits well and stands out in any sort of display. It is very hard to find sizable crystals on matrix that have not been repaired, faked or otherwise unnatural. This one is fully natural and not enhanced. The crystal is 2.2 x 1.7 CM and is nicely balanced on the matrix. Good condition, there are micro edge chips seen with loupe but no really bad damage, the "bottom end" of the crystal is contacted and does not show a clear termination. This quality is now very hard to get in Colombia at any reasonable price if at all. If this was mined today this would be treated, infused, cut and sold in the gem market. It would also be a lot more expensive!

Spring 2019
From this famed old locale in the Urals, a terminated Emerald crystal on matrix with deep green color. A few smaller Emeralds are also present but the main crystal (1.7x 1.5 CM) is dominant on the specimen. The large flat termination face is dusted with a sparkling dusting of Mica that adds some interest as well. The history of the minerals from this region is an incredible story that is still ongoing today.. This is a good representative piece with some edge translucence but not cutting worthy. Not at all a common item in the mineral marketplace, yet quite affordable..

Late Summer 2018
A single fat gem crystal with excellent color, very sharp edges, lustrous faces and fine display impact. 8.9 Grams a few inclusions but with good transparency, this was mined in 2007. A small area of attached shale on the backside/bottom is the only matrix, this is all Beryl. It has gotten very uncommon to find such good single gem crystals in Colombia. Newer methods of treatment, filling and enhancement means these can be consumed by gem cutters for much more expensive jewelry. In excellent condition and better in person.
Beryl var. Emerald on Quartz

Mina El Toro, Chivor Municipio de Chivor

Colombia
5.4 X 4.3 x 3.5 CM (small cabinet/ large miniature)
price: $1200
Worldwide mix summer
Large translucent Emerald crystals protruding from a vuggy Quartz matrix. From a little known mine (Mina El Toro) that is in the Chivor district of Colombia, this is an attractive specimen with rich color. The main crystal is 4.3 CM long and the termination is quite choice. Quartz is a rare matrix for Colombian Emeralds since most are found in Calcite veins. On close inspection the Quartz shows several crystal faces that are distorted and bent, a very odd matrix. Displays well obviously not top facet grade but not priced at 20,000 per carat either. The form and color make this a very attractive specimen that is a fine addition to any suite of Beryls, Colombian minerals or just a collection of nice esthetic pieces.

Spring update
Light to mint green Beryl (Emerald) crystals make up most of this specimen with only a thin shard of matrix showing on one edge. Crystallized Beryla are on all sides, almost a floater. The Quartz prisms are sharp and clear contrasting with the Beryl. Crystallized quartz is rare in Colombian Emerald specimens, much more typical is Calcite or Dolomite. This is from a little known spot in the famed Boyaca region. In Colombia only 2 or 3 mines have ever produced Quartz crystals intergrown with Emerald. There are some chipped or contacted crystals but also many perfect, sharp Hexagons with good transparency and luster.

Spring update
A two-sided specimen holding dozens of light to mid green Emerald crystals that are intermixed with Quartz crystals. Very unusual for a Colombian Emerald specimen, the usual association in Calcite. Prior to our finding this material the only Quartz matrix I have seen or know of for Emeralds is at Penas Blancas and it is very rare there. This little known cut near Coscuez has now produced a few of this rae combo. A choice and rare piece with many small, very clear Emeralds covering both sides of the matrix. With magnification the quality really stands out.

Fall 2015
A classic old Russian Emerald specimen with a sizable (2.7 cm) terminated prism that is well-exposed on its Schist matrix. The crystal is quite transparent with a few inclusions. Some additional Beryl crystals are also on the matrix. We have photographed this with "normal" display lighting, if it is backlit it displays with clarity.
A quite sizable (7.9 CM) and impressive Chinese Emerald with the typical color from this find. This Beryl is not gemmy except on thin edges and not colored by Chromium as are the Colombian Emeralds. Despite that this is still attractive and affordable. The crystal has been repaired (1x) and shows also a natural break and re-healing. A very good addition to a suite of Beryl, Chinese minerals or just as an attractive display piece.
