|
|
#MVM (Minerals - Virtual Museum) / more information about the piece with this link
| Mineral: | Olshanskyite with Roweite and Andradite |
| Locality: | | Shijiangshan Mine, Shijiangshan village, Yinwu, Linxi, Ulanhad League, Inner Mongolia Autonomous Region, China |  |
|
| Dimensions: | Specimen size: 7.5 × 4.6 × 3.4 cm |
| Description: |
The Olshanskyite from the Shijiangshan Mine was previously well-known for its quality, largely overtaking the best known to date for the species. However, a discovery made in 2017 raised the quality to unprecedented levels. The sample, included among the best samples found from this new find, forms elongated and very well differentiated crystals that are clear, colorless and very bright, with sharp crystals. They are on matrix, with Roweite and Andradite crystals with a white coating of a silicate that very probably is altered Andradite.
The specimen has been reviewed, photographed and published as a new discovery of Munich 2017 in the magazine ‘Mineral Up’ on page 62 in number 2017/2 |
