Blue, Purple Tanzanite - 2.29 ct - Antwerp Laboratory for Gemstone Testing (ALGT)

Tanzanite is a strikingly beautiful blue to violet variety of the mineral zoisite, found exclusively in a small area near Mount Kilimanjaro in Tanzania. This particular gemstone, weighing 2.29 carats, displays a captivating blend of blue and purple hues, characteristic of high-quality tanzanite. Its allure stems not only from its vivid colors but also from its rarity, as it was only discovered in the late 1960s and comes from a single geographic location. Tanzanite often exhibits pleochroism, showing different colors when viewed from different angles. With a hardness of about 6 to 7 on the Mohs scale, the gem is suitable for various jewelry but requires some care to avoid scratches and harsh impacts. Certification from respected entities like the Antwerp Laboratory for Gemstone Testing (ALGT) confirms the gemstone's natural origin and quality, enhancing its desirability among collectors and connoisseurs.
