RM1855 Wulfenite
Touissit, Touissit-Bou Beker, Jerada, Oriental Region, MoroccoIn this specimen we can enjoy groups of tabular crystals showing well defined faces and parallel growths. They are interpenetrated between them and accompanied by small but perfect tabular wulfenite crystals. Some of them present small ding, very common in this samples, but this one is really good. The brilliance is good and in thin parts showing transparence. They are very aerial disposed on the matrix.

RM1854 Atzurite
Touissit, Touissit-Bou Beker, Jerada, Oriental Region, MoroccoA prismatic crystal that just looks like the typical ones from Touissit, but a more detailed check shows the unusual richness of the termination, with lots of faces. Definition, brilliance, and color are the outstanding features of this sample. This azurite crystal, in the form of a broad spear point, exhibits electric blue highlights, lustre, and numerous step faces on both sides of the of the crystal. It is a magnificent crystal with only one minor ding/contact on one terminal face, otherwise, it is really aesthetic. A very old specimen, very difficult to get nowadays.

RM1853 Ferro-hornblende
Gairo, Kilosa, Morogoro, TanzaniaInteresting specimen of ferro-hornblende from a little known African locality. Various pseudocubic crystals of deep greenish tone. It is difficult to find specimens of this quality for the species. Named in 1789 by Abraham Gottlieb Werner from an old German term for dark minerals with no ore value and from "blende", meaning to deceive in allusion to it occurring in ore deposits but not yielding any metal and for ferro- indicating Fe2+ as a dominant cation.

RM1767 Gold with malachite and bornite
Bleida Far West, Bou Azzer, Ouarzazate, Drâa-Tafilalet, MoroccoNovelty 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.

RM1763 Smoky-Morion quartz
Cañadas farm, Cerro de la Higuera, Montejícar, Granada, Andalucía, SpainMontejícar is located midway between Granada and Jaén, in the northern limit of the province of Granada. This area is known among mineral collectors for the excellent quartz, smoked to morion, doubly terminated and with very poorly developed prism faces, which gives them a characteristic dipyramidal shape. These specimens are found in banded gypsum and marl from the Trias in a Keuper facies characteristic of the Cortijo Cañadas, in the N of the Montejícar municipal district. In the area there are some interesting ruins of plaster kilns.
