No reserve price - 26 pcs Tanzanite - 9.81 ct - Gem Report Antwerp (GRA) - Violetish Blue/Violet

Tanzanite is a rare and strikingly beautiful gemstone known for its unique violet-blue hues. Discovered only in the 1960s in Tanzania near Mount Kilimanjaro, its limited geographic origin makes it highly sought after by collectors and jewelers. The gem is a variety of the mineral zoisite and displays pleochroism, meaning its color changes when viewed from different angles, often shifting between blue, violet, and sometimes burgundy shades. The 26-piece lot totaling 9.81 carats with a violetish blue to violet color blend represents a significant assembly of fine tanzanite material. Tanzanite's rich color and rarity have made it a popular choice for luxury jewelry, and it is often treated by heating to enhance its vivid colors. Collectors prize stones with strong blue and violet tones, good clarity, and a bright, lively appearance as this combination tends to yield the most attractive and valuable gems. Lab reports from reputable institutions like Gem Report Antwerp add assurance of origin and quality for potential buyers or enthusiasts exploring this fascinating gemstone.
