The gemstone has been photographed under different lighting conditions to present its appearance as accurately as possible. Slight color variations may occur depending on monitor or smartphone settings. Natural gemstones commonly contain internal characteristics formed during their natural growth. These inclusions are normal and are considered evidence of natural origin rather than imperfections. Tanzanite is a highly sought-after variety of zoisite, renowned for its distinctive blue-to-violet coloration, strong pleochroism, and limited geographic occurrence. Large faceted Tanzanites above 5 carats have an impressive visual presence and are especially attractive for statement jewelry and gemstone collections. This 5.49 ct specimen combines substantial size, violetish-blue color, transparency, and a distinctive pear cut.
