Rare Earth Tantalate: Microlite on Pegmatite Matrix

As a key member of the pyrochlore supergroup, microlite is an uncommon calcium-sodium tantalum oxide mineral found strictly in highly fractionated lithium-cesium-tantalum (LCT) pegmatites. Formed in late-stage hydrothermal cavities, crystallised matrix plates of microlite are prized by systematic and rare-species collectors.

Key Specimen Characteristics:

  • Crystal Habit: Sharp octahedral and modified dodecahedral crystals displaying high specific gravity and adamantine-to-resinous luster.
  • Coloration: Ranging from honey yellow and caramel amber to deep reddish-brown and olive tones.
  • Matrix Contrast: Well-crystallised microlite perched securely against snow-white albite or lilac lepidolite plates.

Every piece is 100% natural, untreated, and verified for crystalline integrity.
