Tanzanite is one of the most beautiful gemstones in the world, known for its striking blue-violet hues. It is a relatively new gemstone, discovered only in 1967 in the foothills of Mount Kilimanjaro in Tanzania. This gemstone has since become a popular choice for fine jewelry, admired for its rare beauty and unique color. But how much is a carat of tanzanite worth? In this article, we will explore the factors that affect the price of tanzanite, the market trends, and how to determine its value.
What is Tanzanite?
Tanzanite is a variety of the mineral zoisite, found only in a small area near the base of Mount Kilimanjaro in Tanzania. Its distinct blue to violet color is caused by trace amounts of vanadium, and it can display different hues depending on the angle from which it is viewed. This unique gemstone has become highly sought after in recent decades, gaining popularity for its rarity and mesmerizing color. Tanzanite’s value is also tied to its limited geographical origin, making it more precious over time.
Factors Affecting the Value of Tanzanite
The price of tanzanite, like any gemstone, is determined by several factors. These factors include the quality, size, color, and clarity of the stone. Let’s dive into these elements in more detail.
1. Color
Color is one of the most important aspects when it comes to the value of tanzanite. Tanzanite stones range in color from pale blue to deep violet, with some stones exhibiting a mix of both colors. The most valuable tanzanites are those that show a deep blue or vibrant violet, with a strong color intensity. Stones that display a rich blue-violet or purplish-blue color are the most sought after.
Lighter or less saturated tanzanite gemstones tend to have a lower value compared to their more vibrant counterparts. Therefore, when determining the worth of tanzanite, its color plays a significant role in the overall pricing.
2. Size and Weight (Carat)
The size of a tanzanite gemstone is typically measured in carats, with one carat equaling 0.2 grams. Larger stones are rarer and more valuable, as they are harder to find. Tanzanite tends to be priced higher per carat as the size increases, especially when the stone maintains its high quality and rich color.
Smaller tanzanite stones may be more affordable, but they generally cost less per carat compared to larger stones. It’s also worth noting that tanzanite can be found in various shapes and cuts, which can also influence its price.
3. Clarity
Clarity refers to the presence or absence of inclusions or internal flaws within the gemstone. Tanzanite, like most gemstones, can have natural inclusions that affect its clarity. Stones that are free from visible inclusions are considered more valuable, as they are rarer and more aesthetically pleasing.
While tanzanite gemstones with visible inclusions can still be beautiful, their value is generally lower. Gemstones that are clear or have minimal inclusions are prized for their transparency and brilliance.
4. Cut and Shape
The cut of a tanzanite gemstone can significantly impact its appearance and value. A well-cut stone maximizes the gemstone’s brilliance and color, making it more visually appealing. A poorly cut stone can diminish its overall beauty and reduce its value.
Tanzanite gemstones come in a variety of cuts and shapes, including round, oval, cushion, and pear. The shape of the gemstone can also affect its price. Certain shapes, such as emerald cuts or custom-designed cuts, might be more expensive due to the additional labor and expertise required.
5. Origin
The origin of the tanzanite gemstone also plays a crucial role in its pricing. Tanzanite is only found in one location in the world, near Mount Kilimanjaro in Tanzania. This limited geographical origin makes it a rare and exclusive gemstone.
Tanzanite mined from certain areas within the Tanzanite mining region can be more expensive than others due to factors like the quality of the stone, its depth of color, and its size. The rarity of high-quality tanzanite stones can also increase their market value.
Tanzanite Pricing Trends
Over the years, the price of tanzanite has experienced fluctuations, influenced by various factors including demand, availability, and market trends. When tanzanite was first discovered in the 1960s, it was sold at relatively affordable prices. However, as the gemstone gained popularity and awareness grew, its value steadily increased.
Tanzanite prices peaked in the late 2000s when the gemstone became more widely recognized, but over the past decade, the market has experienced some ups and downs. This volatility can be attributed to various factors, including mining challenges and the limited supply of tanzanite gemstones.
In recent years, the value of tanzanite has been rising again due to its increasing popularity among collectors and gemstone enthusiasts. The rarity of high-quality tanzanite, along with its striking beauty, has made it an attractive option for investors and jewelry buyers.
Current Market Prices of Tanzanite
So, how much is a carat of tanzanite worth in the current market? The price of tanzanite can range from as low as $200 to over $1,000 per carat, depending on the quality of the stone. On average, you can expect to pay between $400 and $600 per carat for tanzanite of good quality.
Larger stones, especially those weighing over 5 carats, can command significantly higher prices. Exceptional stones with deep, vibrant color and minimal inclusions can even exceed $1,000 per carat.
As with any gemstone, prices can vary depending on the vendor, location, and the overall quality of the stone. It’s essential to shop around and consult with trusted gemologists or jewelers to ensure you’re getting a fair price for your tanzanite.
How to Determine the Value of Tanzanite
If you’re considering buying or selling tanzanite, it’s important to understand how to determine its value. As mentioned earlier, several factors contribute to the price of a tanzanite gemstone.
Here’s a simple guide to help you evaluate its worth:
1. Assess the Color
Examine the color of the tanzanite. Is it a deep blue-violet, or does it appear pale or washed out? Rich, saturated colors are more valuable. The ideal tanzanite color is a vibrant blue with violet undertones.
2. Check the Size and Carat Weight
Larger tanzanite stones are generally worth more per carat. Weigh the stone to determine its carat weight, as larger stones tend to be rarer and more expensive.
3. Examine the Clarity
Inspect the stone for any inclusions or internal flaws. Stones with fewer visible inclusions are more valuable, especially if they are eye-clean (free from noticeable imperfections).
4. Evaluate the Cut
Look at the cut and shape of the tanzanite. Well-cut stones that exhibit brilliance and color are more valuable. Poorly cut stones may appear dull and are worth less.
5. Verify the Origin
If possible, determine the origin of the tanzanite. While all tanzanite comes from Tanzania, certain regions may produce higher-quality stones. Be sure to verify the gemstone’s authenticity and origin with a certified gemologist.
Conclusion
Tanzanite is a stunning and rare gemstone, and its value can vary depending on factors like color, size, clarity, cut, and origin. While the average price per carat for tanzanite is typically between $400 and $600, larger stones with exceptional quality can fetch much higher prices. As with any gemstone purchase, it’s crucial to evaluate the quality of the stone carefully to ensure you get a fair price.
Whether you’re a buyer or seller, understanding the factors that influence the price of tanzanite will help you make informed decisions. With its limited supply and growing popularity, tanzanite remains a valuable gemstone that is sure to retain its appeal in the jewelry market for years to come.
