TB92AL0: A new discovery at Tucson 2020. This new mineral species displays, among other notable characteristics, a dichroism: blue "Paraíba" color viewed from the front and yellow with green tints seen from the side (with focused light)
Given its hardness, color and transparency, the mineral falls into the gem category and this, together with the fact that it is a new species as well as its rarity, inevitably makes its price high. Another reason for interest is the high content of Scandium in its composition (around 3.8%)
Laurent Thomas, the person whose name the species carries, presented it at Tucson 2020 and explained to us that although the first news of this new species went out in 2018, the most important find was that of April 2019 and that is the one from which this piece comes.
