It is exciting to be able to offer a number of this type of pieces past more than 100 years, a true oldie.

Group of prismatic crystals, many of them fine, with gree-brown tones, bright and on matrix.

Specimen size: 7.5 × 4.7 × 4.0 cm = 2.95” × 1.85” × 1.57”

17TRX96: Group of Calcite crystals, one of them clearly dominant and very aerial, white in color and outlined with slight twists. The crystals of Calcite grew on a matrix of Pyrite and Sphalerite, and on cream-colored rhombohedral Dolomite crystals, clearly differentiating the area of sulfides from that of carbonates, the latter having precipitated later. A very 'geological' specimen.

Specimen size: 6.8 × 5.3 × 5.6 cm = 2.68” × 2.09” × 2.20”

Main crystal size: 5.0 × 3.0 cm = 1.97” × 1.18”

10DQ: Quartz crystals (variety smoky), one of them clearly dominant, doubly terminated, with well-defined faces and edges, with external and internal inclusions of deep green Chlorite crystals, which give some of the Quartz crystal faces a rough appearance

Specimen size: 3.9 × 2.0 × 1.9 cm = 1.54” × 0.79” × 0.75”

Main crystal size: 3.6 × 1.9 cm = 1.42” × 0.75”

19TXE14: Groups and isolated crystals of Vanadinite, many of them doubly terminated, with sharp crystal forms of short prismatic habit, some with hoppered terminations, translucent and with an intense and uniform orange-red color, in a matrix of manganese oxides forming spherical aggregates. From the most productive vein in the Taouz deposit but with an unusual quality for that deposit.

19MZA11: Small very shiny Pyrite crystals have completely pseudomorphed old Baryte crystals, of which only their original morphology remains, especially in the basal part of the piece, as can be seen in the video. Coming from the Bou Nahas mine in Morocco, which never ceases to amaze us with the multiple presentations of its sulfides, with pyrite being the premier exhibit.

Specimen size: 5.5 × 4.3 × 2.2 cm = 2.17” × 1.69” × 0.87”

Main crystal size: 2.2 × 2.0 cm = 0.87” × 0.79”

18EKD11: Group of Calcite crystals with very sharp pseudohexagonal outlines, completely covered by a second generation of small crystals, also of Calcite, partially dissolved and with small Quartz crystals. At the base there are remnants of matrix reminiscent of the Brazilian or Uruguayan basalts that host amethyst crystals.
We have analyzed this type of specimen due to its genetic complexity and we will send a copy of the analysis to the buyer.

21TLX13: A novelty at the Sainte Marie Virtual 2021 Show.
Bundles of elongated and terminated Azurite crystals that are transparent, with great luster and a very vivid blue color reminiscent of the "electric blue" of the best specimens from Milpillas.
This specimen, in a matrix with Quartz and small remnants of Malachite, comes from finds made in 2021 in the Tazalarht area.

21TZX46: A novelty at the Sainte Marie 2021 Virtual Show.
Coatings of deep green primary Malachite crystals with irregular but distinguishable shapes, with a second generation of centered growths of fine acicular crystals with a silky luster and very vivid color. On limonite matrix.
The specimen comes from recent finds in the Tazalarht area.

16MJM11: A novelty from Morocco, from a discovery in the summer of 2020. White tabular crystals of Baryte partially covered by a perimorphic growth of a mosaic of very lustrous small cubic and octahedral Pyrite crystals. The Bou Nahas Mine, a polymetallic hydrothermal deposit, continues to provide pleasant mineral surprises.
