StarLanka is pleased to announce that their inventory of stones includes the Tanzanite gemstone, which has been selected as Gem of the Year for 2020. In part, the popularity is due to its brilliant blue color. The discovery and popularity of the stone are relatively recent. The discovery occurred in the late 1960s in the Kilimanjaro area of northern Tanzania, near Arusha’s city. The deposits and the mining activities are located in an approximately eight square mile area.
The gemstone is the second most popular blue gem, with only sapphire more in demand. In its natural state, Zoisite can be found in colors ranging from colorless to pink, yellow, and brown. The appeal is in the striking blues, bluish violet, and bluish purple. Heating the transparent crystals improves the colors so that the brown or green stones become blue. The heat treatment brings about the color change by the presence of vanadium inside the structure. The naturally blue gems are highly prized in the market.
The skill of the cutters contributes to the value of each stone. The physical property known as pleochroism makes gemstones appear to have different colors when viewed from different angles. In most instances, the gems are blue when viewed from one direction, but red to violet when seen from a different viewpoint. The cutter examines the rough stones to determine the best orientation to reveal the blue hue.
