Exceptional 135.75 cts Tsavorite Garnet Rough Crystal Lot (4 Pieces) – Merelani Hills, Tanzania Presenting a remarkable lot of four natural Tsavorite (Green Grossular Garnet) rough crystals, ethically sourced from the legendary Merelani Hills in Tanzania. This stunning collection offers a combined weight of 135.75 carats (27.15 grams), featuring substantial individual pieces ranging from 19 to an impressive 50 carats. As seen across the specimen photos, these unheated, untreated rough crystals showcase the classic, highly sought-after vibrant greens—ranging from luminous mint to intense, deep emerald hues. The crystals retain natural etching, conchoidal fractures, and classic crystalline formations, with some pieces exhibiting the iconic, highly contrasting graphite and calcite matrix associated with the Merelani deposit. This lot is a premier offering for high-end lapidary artists seeking yield, or rare mineral collectors wanting substantial raw specimens from an iconic locality. Weight: 27.15 grams / 135.75 carats (Total Lot Weight) Sizes: 19 to 50 carats per piece Variety: Tsavorite (Green Grossular Garnet) Color: Luminous Mint Green to Intense Vivid Emerald Green Condition: Natural rough, unheated and untreated. Exhibits vitreous gemmy windows, natural crystal faces, conchoidal fracturing, and minor localized host-rock matrix. Luster: Vitreous (Glass-like) to slightly greasy on raw faces. Hardness: 7 to 7.5 on the Mohs scale (Excellent durability for future faceting or jewelry use). Locality: Merelani Hills, Lelatema Mountains, Simanjiro District, Manyara Region, Tanzania (The world's primary source for top-tier Tsavorite). Rarity: Extremely High. Tsavorite garnet is estimated to be 200 times rarer than Emerald. Finding rough pieces that exceed the 10-carat mark is highly uncommon; a lot featuring pieces up to 50 carats is a distinct geological rarity. Market worth: Premium. Due to the scarcity of large-size rough in the current market, lot values are appreciating rapidly. Sizable rough pieces of this caliber command high premiums per carat from both custom facetors and global mineral investors. Metaphysical: Tsavorite is revered as a powerful stone of wealth, vitality, and deep emotional healing. Strongly associated with the Heart Chakra, it is believed to help the bearer discover their inner beauty, promote prosperity, and foster a connection with the natural world's restorative energies. Vibrant Saturation: The arresting color of these pieces is driven by trace amounts of vanadium ($V^{3+}$) and chromium ($Cr^{3+}$). Unlike emeralds, Tsavorite requires no oiling or treatments to achieve its dazzling, highly refractive color. The light return and glow of these raw pieces indicate excellent optical properties. Stunning Contrast: Several pieces in this lot feature the dramatic, natural aesthetic of bright, translucent green garnet erupting from minor patches of dark graphite and white matrix. This contrast not only authenticates its Merelani origins but provides a visually striking dynamic for raw mineral displays. Investment Potential: Exceptional. The Merelani Hills remain the only commercially viable source for high-quality Tsavorite. With mining depths increasing and the yield of large rough crystals diminishing, this specific lot—boasting large 19-50 ct sizes—serves as a highly liquid and appreciating tangible asset for the discerning investor. For the true connoisseur of African gem wealth, this 135.75-carat Tsavorite lot represents the apex of natural beauty and rarity. Whether your intention is to facet bespoke, world-class gemstones or to preserve the raw, untamed elegance of the Merelani Hills in a private showcase, these four crystals deliver on every front. Substantial in size, piercing in color, and completely pure in their natural state, this is an unmissable opportunity to acquire a piece of Tanzania's finest geological heritage. Don't let this vibrant, high-yield rough slip through your fingers.
