Discovered in the 1960s, tanzanite has rapidly gained popularity and is now one of the most valuable gemstones in the world. From its fascinating history and rich symbolism to interesting discovery and popular styles, it has a lot to offer.
This article will guide you through everything you need to know about buying tanzanite jewelry, helping you make a confident and informed decision.
Why Choose Tanzanite Jewelry?
Belonging to the zoisite mineral family, tanzanite is known for its vibrant hues and brilliance. Its primary appeal lies in its unique trichroism, meaning it displays blue, violet and burgundy tones depending on the light. This characteristic makes tanzanite jewelry look distinct from other gemstones. Since tanzanite is rarer than diamonds, many buyers see it as both a fashion statement and a long-term investment.
Tanzanite is mined exclusively near Mount Kilimanjaro, making it one of the rarest gemstones in the world. Experts believe that its stone deposits could be depleted within our lifetime, adding to its charm and value.
Moreover, tanzanite was added to the list of birthstones for December in 2002, sharing the month with turquoise and zircon.
In addition to its visual appeal, tanzanite jewelry is also regarded for its symbolic and metaphysical properties. It is believed to bring positivity, enhance focus and self-assurance, promoting mental clarity and concentration. Many also consider it helpful in easing anxiety and stress during challenging times. Moreover, tanzanite is thought to attract good fortune, success and wealth. It may also help regulate spending habits and facilitate money saving.
Fascinating Discovery of Tanzanite
Tanzanite is a relatively new addition to the world of gemstones, discovered only in 1967 in the Merelani Hills of Northern Tanzania, near Mount Kilimanjaro. Legends believe that Maasai herders came across the vivid blue crystals after a lightning storm swept through the region. Mistaking them for a new type of sapphire due, they brought the stones to Portuguese prospector Manuel D’Souza.
He later presented gems to Tiffany & Co, the renowned New York jeweler who immediately realized their potential as a rival to sapphire. Initially, the gem was referred to as "blue zoisite," after its mineral family. However, the name "blue zoisite" was both unappealing and sounded too similar to "suicide," which could hinder its market appeal. To better reflect the gem’s unique origin and boost its marketability, the company rebranded the gem as "tanzanite," in honor of its exclusive source in Tanzania.
What to Look for When Buying Tanzanite
Whether you want to buy tanzanite online or offline, certain factors ensure you are getting quality and value.
1. 4Cs
Color-The most important factor affecting tanzanite’s value is its color. The gem exhibits a pleochroic nature, showing multiple colors from different angles, often blue, violet, or red flashes. Deeply saturated blue-violet or violet-blue tanzanites are the most desirable and command premium prices. Lighter pastel shades can also be attractive but are less expensive.
Clarity- Tanzanite stones without visible impurities are considered higher quality and valuable. For jewelry, opt for eye-clean tanzanite gemstone, where imperfections are invisible to the naked eye. Larger, flawless gems with no visible inclusions command the highest prices.
Cut – Expert cutting enhances brilliance and maximizes the stone’s trichroic effect. Popular cuts include round, oval, cushion and pear. These cuts are able to elevate sparkle, making them popular choices for many jewelry styles. Rare cat’s-eye tanzanite is typically shaped into cabochons to highlight its unique optical effect.

Carat Weight – Larger tanzanites are rarer and more expensive. However, a larger stone with poor color or clarity may not be as valuable as a smaller stone with exceptional color and clarity.
2. Durability
With a rating around 6.5 to 7 on the Mohs scale, tanzanite is softer than some other gemstones like diamonds and sapphires. This makes it moderately durable but still suitable for everyday wear. It requires careful handling and protection to prevent scratching or damage.
3. Treatments
Nearly all tanzanites available in the market are heat treated to enhance their blue color, a standard and accepted practice. The treatment reduces the gemstone's natural brown hues and treated stones are generally assumed unless explicitly stated otherwise.
4. Popular Types of Tanzanite Jewelry
