ET51AG5: Olshanskyite with Roweite and Andradite
The Olshanskyite from the Shijiangshan Mine was previously well-known for its quality, largely overtaking the best known to date for the species. But a very recent find has raised the roof of quality to unforeseen 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 extraordinarily bright, with very 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

TC2580ERY: Olshanskyite with Roweite, Andradite and Wurtzite
Groups of Olshanskyite crystals, with a very elongated shape, transparent, colorless and lustrous. With very sharp crystal forms and related with minor Roweite, Andradite and Wurtzite. Olshanskyites from the Shijiangshan mine were already known for their quality, which far surpassed the best known to date for the species, but a very recent find has raised the quality ceiling to unsuspected levels. From this new find we have been able to choose among the best specimens recovered. We will send a copy of the analysis to the buyer.

SV390NPG: Opal
San Valentín is a very special quarry that has produced a great variety of species even though it is in a region that is not usually known for being mineralogically diverse. Among the curiosities of this locality is this very red Opal found by Miguel David Martínez, and that was in his collection with the number 854.

17TL16: Opal (variety hyalite)
A novelty at Tucson 2014. Transparent botryoidal growth, on matrix. This type of Opal (hyalite variety) has the main virtue of fluorescing even in daylight. In fact, it fluoresces under almost all types of light: LED, fluorescent, daylight and, of course, also under ultraviolet light. In fact, the only light they don't react to is incandescent light. The locality is still very generic but we are sure that over time a more precise locality will become known, as well as the reasons for its unusually intense fluorescence.

HM180TF: Opal (variety hyalite)
These Opals (variety hyalite) appeared for first time during the Tucson Show 2014. Botryoidal nodule very aesthetic and transparent, which shows fluorescence even in daylight, on matrix. In fact it fluoresces under almost any type of light: LED, fluorescent, daylight, and of course also with ultraviolet light. The only light with which they do not react is with incandescent bulbs.

TF66AC6: Opal (variety hyalite)
Very transparent and bright botryoidal growth on matrix. One of the best samples of this find. This type of Opal (variety hyalite), in addition to the fact that it is gemmy and quite aesthetic and stands up well on its matrix, has the extraordinary property of fluorescing in daylight! In fact, it fluoresces in almost all types of light: neon light, LED light, daylight and, of course, UV light. The only light with which it doesn’t react is incandescent. As the find is so new the locality is still very vague; sorry for that, but we are sure that time will clarify the locality as well.
