Tanzanite, a captivating gemstone renowned for its mesmerizing blue and violet hues, belongs to the mineral species known as zoisite. Its chemical composition, expressed as (Ca₂Al₃(SiO₄)(Si₂O₇)O(OH)) + (Cr,Sr), underscores its unique combination of elements. Notably, tanzanite owes its distinctive coloration to trace amounts of vanadium, which imbue it with its breathtaking spectrum of shades.
Origin of the name Tanzanite
The name “tanzanite” pays homage to its country of origin, Tanzania, where it was first discovered. This appellation not only reflects the gemstone’s geographic provenance but also imbues it with a sense of cultural heritage and identity.
Tanzanite made its debut on the global stage in 1968, when renowned jeweler Tiffany & Co. introduced it to the market. Since then, it has captivated the imaginations of gem enthusiasts worldwide, earning acclaim for its rare beauty and exceptional quality.
Geological Formation
The genesis of tanzanite dates back approximately 585 million years to the mid-Ediacaran Period. This period, marked by intense geological upheaval and plate tectonic activity, witnessed the emergence of this rare gemstone. The tumultuous conditions in what would later become the vicinity of Mount Kilimanjaro played a pivotal role in tanzanite’s formation. Specifically, the confluence of extreme heat and geological forces contributed to the crystallization of tanzanite in the earth’s depths.
Deposits of tanzanite are typically situated in the “hinge” regions of isoclinal folds, geological formations characterized by intense folding and faulting. Such geological features provide insight into the intricate processes that shaped tanzanite over millions of years, rendering it a testament to the earth’s dynamic evolution.
Discovery of tanzanite
Tanzanite’s exclusive provenance lies in the Merelani Hills of Tanzania, a region encompassing approximately 7 square kilometers. This limited geographic area hosts the world’s only known deposits of tanzanite, making it a geological marvel of unparalleled rarity.
The serendipitous discovery of tanzanite is attributed to a local herder named Jumanne Mhero Ngoma, who stumbled upon shimmering blue crystals in 1967. This chance encounter marked the beginning of tanzanite’s journey from geological curiosity to coveted gemstone.
Color and Trichoism
One of tanzanite’s most captivating attributes is its phenomenon of trichroism, wherein it displays distinct hues of blue, violet, and burgundy depending on the crystal’s orientation. This optical property adds to tanzanite’s allure, creating a dynamic interplay of colors that captivates the beholder.
Moreover, tanzanite’s appearance is influenced by ambient lighting conditions. Under fluorescent lighting, its blue tones are accentuated, casting a mesmerizing azure glow. Conversely, incandescent illumination reveals the gemstone’s violet hues, infusing it with a subtle, ethereal beauty. This interplay of light and color underscores tanzanite’s multifaceted appeal, rendering it a gemstone of unparalleled visual intrigue.
Heat Treatment
Upon extraction, raw tanzanite often exhibits a reddish-brown hue or appears cloudy due to the presence of a brownish “veil.” To unlock its full potential and enhance its color clarity, tanzanite undergoes a process of heat treatment. This treatment, conducted at precise temperatures, serves to eliminate impurities and transform the gemstone into its characteristic blue-violet hue.
The art of heat treatment is a delicate process that requires skilled craftsmanship and meticulous attention to detail. When executed with precision, it enhances tanzanite’s natural beauty, elevating it to the status of a coveted gemstone prized for its aesthetic allure.
The Birthstone of December
Tanzanite is one of the birthstones for December, alongside turquoise and zircon. The selection of tanzanite for December likely relates to its stunning blue-violet color, which can resemble the icy blue hues often associated with December.In recognition of its significance, the American Gem Trade Association designated tanzanite as the birthstone for December in 2002. This prestigious distinction further underscores tanzanite’s status as a gemstone of enduring allure and symbolic significance.
