卓越したロット 136.40ct プレミアム天然グリーン ツォライトガーネット 原石 Crystals- 26.84 g - (6)

exceptional 134.30 cts Natural Rough Tsavorite Garnet Crystal Lot (6 Pcs) - Merelani Hills, Tanzania

Presented for auction is a remarkable 6-piece lot of natural, untreated Tsavorite (Green Grossular Garnet) rough crystals, boasting a substantial total weight of 134.3 carats. Sourced directly from the legendary Merelani Hills in Tanzania, these specimens exhibit the classic, electrifying green hues that have made Tsavorite one of the most coveted colored gemstones in the world. Several pieces in this lot feature the characteristic dark, metallic graphite matrix naturally associated with the Merelani deposit, authenticating their origin and adding tremendous geological interest. Ranging from 8 to 40 carats, these chunky, translucent to semi-transparent rough crystals offer immense potential for both high-end mineral collectors and bespoke lapidary artists.

Weight: 26.84 grams / 134.3 carats (Total Lot Weight)

Sizes: Ranging from 8.0 carats up to a massive 40.0 carats per crystal.

Variety: Tsavorite (Green Vanadian Grossular Garnet)

Color: Ranging from bright, luminous mint green to deep, vivid apple green.

Condition: 100% Natural, unheated, and untreated rough crystals. Some pieces feature natural crystalline etching and host-rock graphite matrix inclusions typical of the locality.

Luster: Vitreous (glass-like) to slightly resinous on the natural rough surfaces.

Hardness: 7 to 7.5 on the Mohs scale, making it excellent for durable jewelry if faceted, and a resilient specimen for collectors.

Locality: Merelani Hills, Lelatema Mountains, Simanjiro District, Manyara Region, Tanzania.

Rarity: Exceptionally rare. Tsavorite is geologically hundreds of times rarer than Emerald. Finding substantial rough chunks in this size bracket (up to 40 carats) from the primary Merelani deposit is becoming increasingly uncommon on the open market.

Market worth: Highly valuable in both the specimen and rough lapidary markets. Uncut Tsavorite of this size and natural provenance commands a premium, with market value steadily appreciating due to limited mining output and high global demand for untreated green gemstones.

Metaphysical: Known as a stone of pure, unbounded prosperity and vitality. Tsavorite is believed to deeply stimulate the Heart Chakra, promoting benevolence, emotional healing, and a profound connection to the natural world. It is often used to reduce financial anxieties and manifest growth.

Vibrant Saturation: The specimens showcase a glowing, neon-like fluorescence in natural light. This vibrant saturation is derived naturally from trace amounts of vanadium and chromium within the crystal lattice, completely free from any artificial enhancements.

Stunning Contrast: The aesthetic appeal of this lot is heavily elevated by the striking visual contrast present on several of the pieces. The brilliant, translucent green garnet powerfully juxtaposes against the dark, silvery-black metallic sheen of the natural graphite matrix, creating a dramatic and highly photogenic geological display.

Investment Potential: Outstanding. As an untreated gemstone that rivals and often surpasses Emerald in brilliance and durability, Tsavorite's market trajectory continues upward. Large, unworked rough parcels directly tracing back to Merelani represent a tangible, high-yield asset for the future as these deposits yield fewer large stones over time.

This is a rare opportunity to acquire a substantial parcel of virgin Merelani Tsavorite. Whether you are a connoisseur of fine natural minerals seeking to add vibrant, matrix-bound specimens to your display, or an investor looking for high-carat rough with undeniable pedigree, this 134.3-carat lot delivers on all fronts. Unheated, untreated, and unequivocally stunning—do not miss your chance to bid on a piece of Tanzania's most vibrant geological treasure.
