TF71K4: Smoky Quartz with Feldspar

Group of two flat, transparent and doubly terminated Quartz crystals on a matrix of Feldspar crystals, probably Orthoclase. The locality is uncommon.
The matrix has, on its backside, a fissure recemented by Quartz but also repaired (or consolidated). This circumstance is noted on the label from the Bob Jones collection, that we'll send with the specimen.

RA9V1: Smoky Quartz with inclusions, Microcline and Albite (pericline)

From a classic Spanish locality. Group of translucent crystals of Quartz slightly smoky, with phantom growths, very well defined faces and edges, and on a matrix of Microcline and Albite (variety pericline) crystals.
The handwritten label of the Folch collection that we'll send to the buyer notes that it was collected by Folch himself in 1917.

Specimen size: 3.8 × 1.4 × 1.1 cm = 1.50” × 0.55” × 0.43”

RL11I0: Smoky Quartz with Microcline and Albite

The crystals have classic forms and they are very well grown and have very well defined faces and edges. They contrast with the matrix of Microcline on which white Albite has grown.

Specimen size: 9.8 × 7.2 × 3.4 cm = 3.86” × 2.83” × 1.34”

NQ66W4: Smoky Quartz with Microcline and Albite

Single crystal of very deep colored smoky Quartz. It is transparent and bright and it is on a small matrix of Microcline and Albite, with leafy growths of Muscovite. The crystal shows a notable phantom growth at its termination.
Mas Sever Quarry, Massabè (Mas Ceber), Sils, Comarca La Selva, Gerona / Girona, Catalonia / Catalunya Spain (04/2004)
Specimen size: 9.1 × 3.7 × 3.2 cm = 3.58” × 1.46” × 1.26”

NR11F2: Smoky Quartz with Opal

From a very new locality, the prisms of smoky Quartz, which have excellent color and brilliance, form a fence of parallel crystals. A base covered by Opal, which adds contrast and support.
Venero I Quarry (Cadalso I Quarry), Cadalso de los Vidrios, Comarca Sierra Oeste de Madrid, Community of Madrid Spain (2004)
Specimen size: 7.5 × 6.2 × 3.5 cm = 2.95” × 2.44” × 1.38”

AM98M5: Smoky Quartz with Rutile and Hematite

Doubly terminated smoky Quartz crystal, very rich with golden-yellow acicular crystals of Rutile and laminar crystals of Hematite. Very esthetic.

Specimen size: 6.9 × 2.8 × 1.7 cm = 2.72” × 1.10” × 0.67”

EQ67K6: Twinned Quartz

Group of doubly terminated crystals, one of them clearly dominant, extraordinarily flattened because the accentuated growth of two opposite faces of the rhombohedron. The specimen is absolutely clear and has, as a curiosity, some slightly curved faces. At the same time, we suspect, due the position of the small faces on the top, it is twinned.

Specimen size: 5.7 × 4.2 × 0.8 cm = 2.24” × 1.65” × 0.31”
