Beryl var. Emerald
stock #8.1-389
Muzo Mining District
Boyaca, Colombia
2.3 x 1.8 x 1.4 CM (thumbnail)
price: $1950
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 V. Emerald on Calcite
stock #8.1-223
La Marina Mine, Pauna
Boyaca, Colombia
3.3 x 2.1 x 1.5 CM (small miniature/ large thumbnail (toenail))
price: $450
Worldwide mix summer

Fine, deep color Emerald crystal nicely perched on crystalized Calcite. From the La Marina Mine, which is famed for Apatites and Euclase but only rarely are specimen Emeralds seen from here. No repairs, the hexagon of Beryl has some etched faces and one one edge a contact but otherwise it is a very choice little gem crystal on classic Colombian matrix. It has gotten very hard to source Emerald specimens in Colombia that are not color enhanced, repaired or priced at crazy levels. This is a very reasonable and attractive peice.
Beryl var. Emerald on Quartz
stock #18.1-053
Mina El Toro, Chivor Municipio de Chivor
Boyaca, 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.
SOLD Beryl var. Emerald- Gem crystal
stock #SOLD 18.1-250
Muzo Mining District
Boyaca, Colombia
1 x .8 x .7 CM (thumbnail)
price: $0
Worldwide mix summer

Single crystal with classic form, good color and clean basal termination. Ex Larry White collection, 6.38 Carats and untreated. This is cutting quality but has survived as a specimen. From the Muzo area (Boyaca, Colombia) it is worth noting that there are no Emerald mines in Muzo itself despite many labels to that effect. The river valley outside the municipality spans several towns and this is the source of this specimen. The Emerald market in the town of Muzo is where most of these are graded and sold. An older piece in good clean, undamaged condition.
Beryl var Emerald
stock #18.1-239
Carnaiba Mine, Pindobacu, Campo Formoso
Bahia, Brazil
2.3 x 1.5 x .9 CM (thumbnail)
price: $160
Worldwide mix summer

A flattened Emerald prism that is doubly terminated (crude at one end), translucent and has a few dark inclusions. From the Camp Formoso zone of Bahia, Brazil, this was in the Hitchings collection and came out over 20 years ago. This zone still produces some small Emeralds but much less often than in the past. On our r visit there last year we did not find a single good specimen to purchase, the mines seem to be minimally active. This is a good example of the style of Emerald from this region, and shows well the typical flattened hexagon form.
Emerald with Quartz crystals
stock #18.1-205
Mina Amarillial, Cosquez, Municipio de Muzo
Boyaca, Colombia
4.2 x 2.2 x 1.9 CM (miniature)
price: $480
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.
Beryl var. Emerald wih Quartz
stock #18.1-056
Mina Amarillial, Cosquez, Municipio de Muzo
Boyaca, Colombia
5.4 x 4.8 x 2.6 CM (cabinet)
price: $850
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.
Beryl Var Emerald, Rare Locale (Norway)
stock #16.1-250
Byrud Emerald Mine, Minnesund
Eidsvoll, Norway
5.6 x 3.8 x 2.5 CM (cabinet)
price: $220
Spring update

Good quality gem clear emeralds on matrix from this seldom seen locale. This mine closed in 1909 after just 10 years, and produced a few good Gem crystals but was not productive enough to compete. It is possible today to visit the dumps and a few Emeralds have been found but usually much smaller than this one. Norwegian Emeralds of quality are very rare in the market. The largest crystal here is 1.4 CM long with very good color and clarity, but not terminated, with chipping and broken areas as seen. Despite the damage it is far better than typical from this locale and this is a choice piece for the area. The color here is due to Vanadium, not Chrome as seen in Colombia. The quality is better than typical Vanadium Beryls at other localities.
