It has become easy to overlook vanadinite from Mibladen due to the plentiful supplies available in the recent past, but specimens from one pocket collected last year warranted a closer look.
| Mineral: | Vanadinite |
| Locality: | | Mibladen (Mibladen mining district), Midelt, Midelt Province, Drâa-Tafilalet Region, Morocco | |
|
| Dimensions: | 2.8 x 5.5 cm |
| Description: |
| In May 2016 one of the local artisanal miners hit a pocket of vanadinite that was reminiscent of the specimens from Taouz. The vanadinite crystals are attached to stalactitic black manganese oxides. The entire pocket was acquired by one dealer, who had them at Tucson. |

The Bor Pit at Dal'negorsk has produced nice datolite crystals from time to time. In November 2016 some very fine datolites were collected. The specimens consisted of glassy, mint green crystals forming intergrown groups, many associated with milky quartz showing interference growth from calcite. Here are two specimens from this find.
| Mineral: | Datolite |
| Locality: | | Bor Pit, Dalnegorsk B deposit, Dalnegorsk, Dalnegorsk Urban District, Primorsky Krai, Russia | |

Tobi, I believe most of the color is iron surface staining. It could probably be removed with oxalic acid, but I prefer to leave it as is. Everyone has clear quartz :>)
