RM1816   Vladimirite with Talmessite
More photos

Vladimirite specimens from Aït Ahmane are among the world's best for the species. It is a rare arsenate that forms aesthetic rosettes of tabular to fibrous crystals, very sharp and colorless. They are accompanied by white aragonite and pink talmessite. These specimens were found in the walls near the entrance of the galleries of the 53rd vein of this Moroccan mine. The SEM-EDS analysis will be sent to the buyer.


Size: 4.2 x 3.3 x 2.8 cm.

RM1767   Gold with malachite and bornite
More photos

Novelty obtained on my last trip to Morocco (02/2018). These are brilliant aggregates of gold formed by numerous crystals rich in faces, curved faces and disposed on a matrix of quartz. The SEM-EDS analyzes show that this gold contains a small percentage of silver (<1% weight). They are accompanied by fibrous aggregates of malachite and gray bornite crystals. This specimen stands out for the contrast between the brilliant gold and the green/gray matrix. An exceptional piece. Bleida is a mine located on the eastern rim of the Bou Azzer district.

RM1755   Gold, var. electrum and Erythrite
More photos

These specimens show a matrix formed by arsenates such as erythrite and associated sulphides and arsenates of cobalt and iron. We can observe on both the presence of arborescent, filiform and laminar gold aggregates. SEM analysis has shown that this is a variety of gold rich in silver (23-24%w): electrum.
Under loupe, we can enjoy that some of these gold aggregates are formed by small crystals of octahedral to cubic forms. We can theorize a secondary genesis for this gold-electrum. We have analyzed the matrix of these specimens observing that the bright metallic matrix corresponds to a mixture of cobalt arsenides, probably skutterudite, and other sulphides. We will send all analyzes to the buyer. The deposit where the electrum appeared has been totally covered by mine lands, so more samples can not be obtained on the field. A very rich gold-electrum specimen.

A very aesthetic specimen that shows a vug in the sulphide matrix, partially covered by tabular lanceolated crystals of erythrite. They are disposed very aerial in elegant radial aggregates. Intense color and transparence. They are accompanied by small groups of pale pink almost colorless talmessite-wendwilsonitecrystals of  and almost black crystals of arseniosiderite. All standing out on the dolomite. A sample of very good quality and that under increase makes us enjoy these arsenates. We will send all the analytical results to the buyer.

Rich specimen formed by several isolated crystals of talmessite, translucent to transparent, defined, from pink to orange. They are disposed on a matrix with bright calcite crystals and green crystalline aggregates of conichalcite. The sample has been analyzed by SEM-EDS and Raman. The results indicate a very low Co content and the Raman indicates that it is talmessite. We will send the buyer all the details.

RM1697   Wendwilsonite with aragonite and cobaltaustinite
More photos

Aesthetic specimen of wendwilsonite formed by numerous sized and isolated crystals, transparent, very well defined, some of them doubly terminated. With an intense and uniform pink color. We also observed some aggregates with a yellowish green tone; the SEM-EDS analysis indicates that it is a rich Cu cobaltaustinite that curiously presents a remarkable content in Zn and Ni, something unusual. They are disposed on a matrix with brilliant crystals of calcite and dolomite. The sample has been analyzed completely, so we will send the buyer all the results.
