What is your favorite gemstone? Do you own a tanzanite jewelry statement? Vibrant color gemstones celebrate a long and revered history, donned by early kings, monarchs and royals. On the contrary, incredibly sparkling tanzanite gemstone is a relatively new discovery and holds a brief history. However, it is equally prominent and sought-after as other precious varieties like diamonds, sapphires, rubies and emeralds.
What is Tanzanite
Discovered in 1969, it is formed from crystalline mineral zoisite. Although, zoisite is considered an extremely abundant mineral, tanzanite is a rare-to-find gem because of the presence of chemical element, vanadium. This December birthstone is widely found in see-through, blushing blue color, which reflects tints of violet and purple under monochromatic light. In fact, it the most popular blue gemstone after sapphire and has an orthorhombic structure that radiates three different colors under three different lights.
Tanzanite crystals are commonly used to fabricate fine jewelry, embellished dresses, tiaras and antique artifacts.
Origin and Occurrence
Natural Tanzanite is only mined in the foothills of Mt. Kilimanjaro, Tanzania and thus, is extremely rare. Finest quality tanzanites are known to have single origin, making it a popular and singular choice. Legends has it that first crystals was discovered in 1967 when a Masai tribesman unearthed a cluster of dazzling, transparent blue stones while searching for deep red rubies.
At first, miners thought that they were distinctively vibrant sapphires, but after studying their complex composition and structure, an exceptionally vibrant crystal and gemstone was added to the world of gemology. Knowing the fact that it can only be extracted from a 4-kilometer square area near Mount Kilimanjaro, this luscious sparkler is becoming rarer.
What color is more valuable?
More technically, tanzanite is supposed to exhibit trichroism, displaying varying shades of blue and purple in different light sources. From a rich, velvety blue to exquisite violet, its color intensity varies from better to best and best to heirloom. Nonetheless, glassy, cornflower blue dominates crystal’s color and grade quality. It is interesting to know that heat treatment is done to most tanzanites available to enhance and deepen the brilliance of blue color. Due to the limited supply of excellent stones, most retailers sell heat-treated tanzanite jewelry, which is equally authentic and refined.
