Rare 2.37ct Pear-Cut Color-Change Magnesio-Axinite Presenting a true curiosity of the mineral world: a 2.37-carat Magnesio-Axinite with a dramatic “day-to-night” personality. While traditional Axinite is known for its earthy browns, the Magnesio-axinite (or Axinite-Mg) variety is the rarest species in the group. This specimen features a sophisticated color change, appearing as a cool, misty bluish in daylight and shifting to a soft, elegant pinkish under incandescent light. The pear shape is particularly effective for this species, as it highlights the gem’s strong pleochroism—the ability to show different colors from different angles—alongside its primary color-change phenomenon. Gemstone Specifications Species: Magnesio-Axinite (Axinite-Mg) Weight: 2.37 Carats Shape: Pear Dimensions: $11.7 \times 6.7 \times 5.1 \text{ mm}$ Clarity: Eye Clean (Incredibly rare for this species) Cut: Mixed Phenomena: Color Change (Bluish to Pinkish) A Collector’s Treasure What makes this stone a “museum-grade” specimen is the combination of its size and clarity. Magnesio-Axinite is notoriously difficult to find in “Eye Clean” quality; most crystals are heavily included or only found in small shards. At 2.37 carats, this stone offers a significant face-up presence that makes it a perfect centerpiece for a custom-designed pendant or an avant-garde engagement ring. Beyond its color change, this stone is a “phenomenal” gem in every sense—it is both pyroelectric (generates electricity when heated) and piezoelectric (generates electricity under pressure), making it as scientifically fascinating as it is beautiful. Market Insight: Magnesio-Axinite from the Merelani Hills of Tanzania is highly sought after by “rare stone” investors. Clean specimens with a distinct blue-to-pink shift are considered the pinnacle of the species.
