Columbite
stock #8.AE-699
Sao Jose do Safira
Minas Gerais, Brazil
4.1 x 3.1 x 1.5 CM (miniature)
price: $180
Late Summer 2021

A single, blocky but somewhat tabular Colombite crystal. Distinct although rather crude, the crystal is fully terminated and moderately lustrous. An older piece from Sao Jose do Safira (Brazil) this is a very good miniature of this commercially important pegmatite mineral that is not often considered "pretty".

Phenakite - gem Brazilian crystal
stock #21.1-290
Rio Piracicaba
Minas Gerais, Brazil
2.6 x 1.7 x 1.5CM (thumbnail)
price: $360
Late Summer 2021

A hefty (7.6 gram), sharp and glassy Phenakite crystal from old finds in Minas Gerais (Brazil). It is hard to be certain but it certainly looks like this crystal is twinned; most are. The underside (or backside) has a large rehealed and recrystallized area that had been broken long ago. There is an unhealed break on one edge so this is not perfect 360 degrees but the display side looks flawless. The transparency and luster are great in person, this is a good sized and flashy crystal from a locality that has become a classic in Brazil but seems to be no longer producing.

Spessartine - etched gem crystal
stock #8.AE-840
Navegadora Mine, Penha do Norte, Conseheiro Pena, Doce Valley
Minas Gerais, Brazil
3.1 x 2.3 x 1.5 CM (thumbnail)
price: $340
Late Summer 2021

A very pretty example thumbnail specimen of a gem Spessartine from the famed Navegadora finds. This is 17.4 grams and the insides are flawless, pure facet grade gem. With backlighting this glows like red glass. The exterior surface is fully etched with complex geometric patterns. These etched zones form in steps and ramparts that are very sharp.

Magnesite with Uvite
stock #21.1-174
Brumado
Bahia, Brazil
6 x 4.3 x 3 CM (cabinet)
price: $1200
Late Summer 2021

A killer, well crystalized Magnesite with the addition of yellow to green Uvite crystals from the now classic finds at Brumado. These are considered by most collectors to be the very best Magnesites ever found worldwide, and this is a superb example. This is a very early specimen from the first imports of the late Luis Menezes, and with a rare perfection and quality. The Magnesite is super clear, very sharp and the largest crystal is 3.4 CM. We have not seen any good or new specimens for the past few years. The arrangement of the rhombs on this specimen is especially esthetic and the Uvites are also glassy, colorful and add a nice contrast.

Siderite - gemmy crystals
stock #21.1-266-(B9)
Morro Velha Mine, Nova Lima, Iron Quadrangle
Minas Gerais, Brazil
6.1 x 4.3 x 3.1 CM (cabinet)
price: $160
Early summer 2021

Cluster of transparent to translucent Siderite crystals with stepped and modified Rhomb forms dominating. With backlighting this glows a deep honey-yellow color and is quite lustrous. In good shape overall there are some rough spots but none are major. The Siderite from this locale is some of the best in the world. The largest flattened rhomb on this piece is 3.1 CM across, and has sharply stepped faces.

Spessartine - etched gem crystal
stock #21.FC-007
Navegadora Mine, Penha do Norte, Conseheiro Pena, Doce Valley
Minas Gerais, Brazil
3.8 x 2.8 x 2.5 CM (miniature)
price: $1600
Early summer 2021

A very lustrous, complete Spessartine crystal with a tiny sliver of Albite attached. From the unique and world famed Navegadora claim in Minas Gerais, this is completely etched and recrystallized with fine geometric structures on all sides. In person this looks like red glass. Fully gemmy and transparent, when backlit the entire piece glows a brilliant red. In super condition, a very close exam finds only a very small rough edge that is not seen from most any angle, this is essentially a perfect floater. The etching has gone so far as to create small geometric cavities and tunnels through the mass of the Garnet. A modern classic, 30.2 Grams and all gem.

Elbaite
stock #20.1-279
Santa Rosa Mine, Itambacuri
Minas Gerais, Brazil
2.6 x 1.3 x 1.3 CM (thumbnail)
price: $80
new year 2021

A zoned green flat top terminated Elbaite crystal from old finds at Santa Rosa. The crystal has good glassy luster, moderate transparency and only one small .5 mm chip. Weighs 7.4 Grams, this is priced below typical market rates. Pretty, affordable tourmaline that glows well when backlit.

Fluorapatite with Elbaite
stock #20.1-085
Pederneira Mine, Sao Jose da Safira, Doce Valley
Minas Gerais, Brazil
6.3 x 4.3 x 4.7 CM (cabinet)
price: $1650
new year 2021

A very fine, super colorful and very unusual Apatite from the famed Pederneira Mine. The Apatite crystals show several generations of growth and color zoning quite different from the tourmaline the mine is famed for. This specimen also has a bi-colored, doubly terminated Elbaite crystal on the backside that is 4.7 CM long, a nice addition. The Apatites have sharp flat terminations and colors zones in purple, blue, orange-red and some dark green. These also show well some selective growth and etching with areas of re-crystallization. This makes for a complex and especially interesting presentation that looks fine from several angles. Excellent condition with no damage, this is the best Apatite I have seen from Pederneira, and would be a fine piece from anyplace. Vividly fluorescent with a zoned responses corresponding with the daylight color areas.
