Describing this mineral cluster as rare is placing an extreme understatement; Olshanskyite, an extremely rare Borate mineral, had only been confirmed as small microcrystals until the mid 2017s when a surprise find from Shijiangshan Mine in Inner Mongolia found these pockets of borate minerals, including another already rare mineral: Roweite. Currently the Shijiangshan Mine is the only locality on Earth thus far to have produced centimeter large crystals of Olshanksyite; the other two known localities are the Fuka Mine in Japan, and Titovskoe B Mine in Siberia, Russia, both of which produces sub millimeter crystals .
This specimen had the rare opportune makeup of having both of these minerals in one sitting making this an opportunity of a lifetime to have, as well as the immense size of the specimen makes it an even harder to miss opportunity! The brown Roweite crystals are extremely well formed, resembling that of Baryte blades, while the very sharp and translucent clear Olshanskyite crystals find themselves nestled in and throughout the entire specimen with notable vugs filled with radiating sprays of these rare crystals (captured in the photos) and sitting on a crystalline Quartz matrix while showcasing the extreme sharpness of each crystal's terminations and clarity.
The chemical formula for the minerals are as follows:
Olshanskyite: Ca2[B3O3(OH)6](OH) · 3H2O

Please note: some elements on this page have been translated automatically.Exemplaire de fluorine très bas en qualité, vert pâle et les cristaux mal définis avec 3 pointes émoussées. On pouvait s'attendre à mieux avec
une fluorine en provenance d'Afrique du Sud. WARNING !Dear Sir/Mdm,
Firstly, I apologize for the displeasure you have had with the mineral we had sent. It was not our intention to deceive or otherwise. We are mineral collectors just like you. While it is unfortunate that the quality was not up to your standards, we stand by our belief that we had fairly represent this piece. The pictures and photographs we had put up had not been edited in any way, and the blemishes, if any would be shown rather than hidden in our photographs. The fluorite in question does indeed come from South Africa in the Riemvasmaak as we had personally obtained them during a trip over there.
While we do understand your unhappiness, we find that the Warning as unwarranted and unnecessary.
While your experience was unfortunate, it is definitely not normal and we would have appreciated a personal message to which we may solve any issue. Regardless, wish you only the best and a very blessed year to come!
Looks different to the photos- actually better. No damage, nice piece

However, I had stated in the description its size. It was also on the title and that clearly stated its size as well.
Unfortunately, your negative feedback was uncalled for without first reaching out to us for clarification about the size, of which it was clearly stated everywhere, or your displeasure.
Salut, je comprends que vous n'êtes pas satisfait de la taille de l'échantillon.
Cependant, j'avais indiqué dans la description sa taille. C'était aussi sur le titre et cela indiquait clairement sa taille.
Malheureusement, vos commentaires négatifs ont été déplacés sans d'abord nous contacter pour obtenir des éclaircissements sur la taille, dont il a été clairement indiqué partout, ou votre mécontentement.
