INTRO: Tanzanite is one of the most captivating gemstones in the world, known for its vibrant colors and unique origins. This exquisite stone has gained popularity not only for its beauty but also for its rarity and fascinating characteristics. In this article, we will explore ten intriguing facts about tanzanite, shedding light on what makes this gemstone truly special.
Tanzanite is 1,000 times rarer than diamonds today.
Tanzanite’s rarity is one of its most compelling features. While diamonds are often found in multiple locations around the world, tanzanite is exclusively found in a small region near Mount Kilimanjaro in Tanzania. Geological surveys estimate that the supply of tanzanite is extremely limited, making it approximately 1,000 times rarer than diamonds. As demand for this stunning stone continues to grow, collectors and jewelers alike are increasingly recognizing its value, further enhancing its allure in the gemstone market.
Its unique color comes from the presence of vanadium.
The remarkable blue-violet color of tanzanite is a result of the presence of vanadium within the mineral’s crystal structure. This element interacts with light in such a way that it can produce a spectrum of rich hues. The most sought-after tanzanite is a deep blue, but depending on the lighting and the way light refracts through the stone, it can also reveal shades of purple and burgundy. This distinctive coloration has made tanzanite a popular choice for gemstone enthusiasts, as its stunning shades evoke an emotional response reminiscent of the twilight sky.
Tanzanite was discovered in Tanzania in 1967.
Tanzanite was first brought to the world’s attention in 1967, when a Maasai tribesman discovered the striking blue stones in Tanzania. The discovery occurred in the Merelani Hills, close to Mount Kilimanjaro. Initially, the stones were thought to be another type of sapphire, but further examination revealed their unique properties. This relatively recent discovery highlights how new gemstones can emerge, adding to the diversity of the gemstone market. Since its introduction, tanzanite has captured the hearts of gem lovers and collectors around the globe.
The gemstone is a variety of the mineral zoisite.
Tanzanite is classified as a variety of the mineral zoisite, which itself is part of the epidote group of minerals. Zoisite can occur in multiple colors, including green, brown, and pink, but tanzanite’s distinct blue-violet hue sets it apart. The unique formation conditions under which tanzanite occurs contribute to its distinct properties, including its color and crystal structure. Understanding its classification helps gemologists and jewelers better appreciate the complexities of this extraordinary gemstone.
Tanzanite can display three different colors in one stone.
One of the most fascinating features of tanzanite is its pleochroism, which allows the stone to exhibit three different colors when viewed from different angles. Depending on the orientation and lighting, tanzanite can show blue, violet, and burgundy hues, making it a truly dynamic gemstone. This characteristic not only enhances its visual appeal but also adds an element of surprise and intrigue for those who wear it. Jewelers often cut tanzanite in specific ways to maximize this effect, resulting in stunning pieces that seem to change before the viewer’s eyes.
The name "tanzanite" was coined by Tiffany & Co.
The gemstone was given the name "tanzanite" by the famous American jeweler Tiffany & Co. in 1968, shortly after its discovery. The name was chosen to reflect its geographic origin, emphasizing its uniqueness and positioning it as a luxury product. The rebranding helped elevate tanzanite’s status in the gemstone market, creating a sense of exclusivity that contributed to its rapid rise in popularity. Tiffany’s marketing strategy played a significant role in introducing this gemstone to the world and remains influential in the perception of tanzanite today.
Its Mohs hardness score is between 6 and 7.
Tanzanite has a Mohs hardness score ranging from 6 to 7, which places it in the medium range for gemstones. This hardness indicates that while tanzanite is relatively durable, it is still susceptible to scratches and damage if not handled with care. For comparison, diamonds score a perfect 10 on the Mohs scale, making them the hardest known natural material. Jewelers recommend setting tanzanite in protective settings and advising wearers to avoid exposure to harsh chemicals or abrasive materials to maintain its beauty over time.
Tanzanite has an impressive pleochroism effect.
The pleochroism effect in tanzanite allows viewers to see different colors from different angles, making it one of the most visually dynamic gemstones available. This characteristic occurs due to the unique way light interacts with the crystal structure of tanzanite, as it has a complex arrangement of atoms that can polarize light. The interplay of colors can create a mesmerizing visual experience, often prompting admiration and intrigue. This optical phenomenon makes tanzanite an appealing choice for jewelry, as each piece can appear distinct depending on the angle of view.
The gemstone is often heat-treated for better color.
To enhance its color and clarity, tanzanite is frequently heat-treated, a common practice in the gemstone industry. This process can intensify the blue and violet hues, making the stone more visually appealing and valuable. While heat treatment is widely accepted and expected for tanzanite, it is important for buyers to ensure that they are purchasing stones that have been ethically sourced and properly treated. Transparency in the treatment process is essential for maintaining trust between gem dealers and consumers.
Tanzanite is the birthstone for December and symbolizes love.
As the official birthstone for December, tanzanite carries significant meaning. It is often associated with love, loyalty, and communication, making it a thoughtful gift for those born in this month. Its rich, vibrant colors are thought to evoke feelings of warmth and tranquility, further enhancing its appeal as a sentimental gemstone. In addition to December birthdays, tanzanite is also popular for anniversaries and special occasions, symbolizing the deep emotional connections shared between loved ones.
