A specimen of great quality for the species, superior in definition and appearance to those previously known.

It comes from an imprecise locality located somewhere within Vangaindrano District, an administrative division of Atsimo-Atsinanana Region, in southeastern Madagascar. In the absence of a more precise location, the district is used as the general geographical reference. This area is known for various mineralogical finds, although many localities remain poorly documented or unnamed.

From a geological point of view, the region belongs to the Precambrian crystalline basement of Madagascar, dominated by high-grade metamorphic rocks such as gneisses and granulites. Sapphirine typically occurs in high-temperature and high-pressure assemblages, associated with granulite-facies metamorphic conditions, often in paragenesis with Mg- and Al-rich minerals.

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.
Together with the specimen we will give the buyer an original label from Laurent Thomas, signed by him.

The specimen has been photographed and published in the magazine ‘Paragénesis’, number 01/2025, page 110

Maromby lies within the Tranomaro–Maromby mining area (southern Madagascar), known for mineralization related to metamorphic rocks and pegmatitic bodies, including gem occurrences and diverse mineral assemblages in small deposits and local workings.

Specimen size: 11.0 × 9.5 × 2.2 cm = 4.33” × 3.74” × 0.87”

MG56AL4: Columbite crystal, very rich in crystal faces and with very well defined faces and edges. Rich in terminal faces too and with a clear scepter habit in the Columbite crystal itself.
District Analalava, Sofia Region  Madagascar

Specimen size: 3.9 × 2.1 × 1 cm = 1.54” × 0.83” × 0.39”

SV2110TDR: Floater crystal of Corundum with a very marked pseudo-hexagonal outline and a very deep and uniform mauve color, flattened, with triangular growth striations and remnants of Mica matrix.
The specimen was set in a jewelry-type box with a handwritten label from an unknown collection attached, which will be delivered to the buyer of the piece.

Specimen size: 1.1 × 1 × 0.3 cm = 0.43” × 0.39” × 0.12”

TLM46AP1: Dravite-Elbaite (Series) single crystal of good size, terminated by the pinacoid and the faces of a very flattened rhombohedron. The crystal has intense reddish reflections and, curiously, analysis has determined that it belongs to the Dravite-Elbaite (Series)
We will send a copy of the analysis to the buyer.

Specimen size: 12.1 × 7.1 × 6.5 cm = 4.76” × 2.80” × 2.56”

TFA67AP9: Doubly terminated floater Fluor-liddicoatite crystal, with the lower termination poorly defined, even crude, but complete, and the upper one with the faces of a sharp pyramid. The crystal is between transparent and translucent, so it needs a strong light to show the intense red color that is dominant throughout the crystal, with yellow areas with golden reflections on the terminations.
The specimen has been analyzed and we will send the buyer a copy of the analysis.

SV290MXR: Very sharp doubly terminated Tremolite crystal, with rounded faces and edges in the upper termination, very lustrous and transparent and implanted in a cavity of a calc-silicate rock with abundant small colorless crystals which are also Tremolite. An interesting perfectly crystallized amphibole, something not very common for a mineral species like Tremolite.
The species has been analyzed and we will send a copy of the analysis to the buyer.
