FM36AA6: "Phantom" Quartz with Chalcopyrite, Cassiterite and Arsenopyrite
Transparent Quartz crystal with a very sharp phantom, its back side partially coated by Dolomite and by Cassiterite microcrystals, with Arsenopyrite and a group of very sharp and bright Chalcopyrite crystals. From the Jan Buma collection, and a rarity for Yaogangxian in that there is no Fluorite on the specimen!
Yaogangxian Mine, Yizhang, Chenzhou Prefecture, Hunan Province  China
Specimen size: 6.1 × 3.1 × 3.1 cm = 2.4” × 1.2” × 1.2”
Price: [SOLD]
Blue Quartz with Magnesioriebeckite inclusions.
N58KI0: Blue Quartz with Magnesioriebeckite inclusions
Color and luster are especially intense. Crystals are practically dipyramidal due to the minor development of prism faces. Blue color is due to the presence of fibrous Magnesioriebeckite.
Acedo Claim (Juanona Quarry), Juanona, Antequera, Comarca de Antequera, Málaga, Andalusia  Spain (1988)
Specimen size: 5.4 × 4.3 × 2.4 cm = 2.1” × 1.7” × 0.9”

Main crystal size: 0.5 × 0.3 cm = 0.2” × 0.1”
Price: [SOLD]
Blue Quartz with Magnesioriebeckite inclusions.
N9HW1: Blue Quartz with Magnesioriebeckite inclusions
Crystals with a dipyramidal shape, prism faces scarcely developed, good luster and bluish color due to inclusions of Magnesioriebeckite. They are on a serpentinite matrix.
Acedo Claim (Juanona Quarry), Juanona, Antequera, Comarca de Antequera, Málaga, Andalusia  Spain (2000)
Specimen size: 6 × 3.5 × 4.7 cm = 2.4” × 1.4” × 1.9”
Price: [SOLD]
Blue Quartz with Magnesioriebeckite inclusions.
N10DH5: Blue Quartz with Magnesioriebeckite inclusions
Group very rich in crystals with dominant apparently dipyramidal shape (made by two rhombohedra) because prismatic faces are nearly not existing which is uncommon in Quartz crystals. The luster of its faces is excellent.
Acedo Claim (Juanona Quarry), Juanona, Antequera, Comarca de Antequera, Málaga, Andalusia  Spain (1988)
Specimen size: 8.3 × 7 × 5 cm = 3.3” × 2.8” × 2.0”

Price: [SOLD]
Blue Quartz with Magnesioriebeckite inclusions.
N11TL3: Blue Quartz with Magnesioriebeckite inclusions
On an ophitic rock matrix, a group of Quartz crystals showing an equidimensional shape, some of them with cubic shape, due to the minor development of prism faces. Precise analysis showed that their deep blue color is due to fibrous inclusions of Magnesioriebeckite.
The specimen has been reviewed and published in the magazine ‘Lapis’ on page 50, volume 37, number 6, June 2012

Doubly terminated and twinned Quartz.
RJ63I7: Doubly terminated and twinned Quartz

Doubly terminated Quartz with Baryte and inclusions.
NM87P2: Doubly terminated Quartz with Baryte and inclusions
Two very bright and well defined doubly terminated crystals with abundant inclusions and with Baryte. The secondary crystal is slightly flattened by an overgrowth of two opposite faces of one of the terminal rhombohedrons. The sample is from a recent find of a big geode in the locality. Unfortunately only a few specimens were saved and complete. The Emilio mine is very well known for colorless Fluorite crystals but Quartz is very uncommon there.
This specimen was photographed for the ‘Sainte-Marie Show 2009’ section of the magazine ‘Minéraux et Fossiles’ and appears on page 17 of number 383.

Price: [SOLD]
Doubly terminated Quartz with Calcite.
TD16H8: Doubly terminated Quartz with Calcite
The crystal is doubly terminated and has the short prism typical of the locality. It is transparent and bright and has attractive inclusions of hydrocarbons and the beginning of “windows” on some of its terminal faces. We call attention on the position of the crystal on the matrix that enhances the esthetics of the specimen as well as increases its value because specimens of Quartz with matrix are pretty unusual in Berbes.
This specimen was photographed and published in the magazine "Lapis" number 7-8 / 2013, page 23
