Beautiful, deep blue and incredibly luxurious, tanzanite is highly valuable and deserves worthy offers. One of the rarest gemstones on earth, tanzanite is used in all kinds of jewelry.

Most recently, in November 2013, a Henry Dunay 18K gold, tanzanite and diamond ring was sold for $22,500 at the same auction house.

Here are ten things you need to know about selling rubies to make sure you receive the maximum value.

Tanzanite Can Only Be Found in One Place

As the stone’s name suggests, tanzanite has been found in just one part of the world to date: Tanzania. The deposits lie in the foothills of Mount Kilimanjaro, and the entire mining area is minuscule at just about five square miles in overall size.

It Gets the Blue Color Only After Heated

Tanzanite is a variety of zoisite, and at first sight, it is a reddish-brown to greenish to reddish-yellow color. Only after being heated to 600 degrees Celsius do the stones take on the royal blue to violet hues they are prized for.

Tanzanite is a Very Recent Discovery

Tanzanite has existed within the earth’s mantle for millions of years, but the gem was only discovered in 1967, making it among the newest to gain popularity. Emmanuel Merishiek Mollel is credited with its discovery; he was a tailor who prospected for gold in his spare time. When he first spotted what later became known as tanzanite, he thought it might be peridot but quickly discovered that the gems he found atop a ridge were something completely different.

Tiffany & Co Renamed Tanzanite

After scientists began calling the new discover “blue zoisite” Tiffany & Company renamed it and marketed it heavily, famously stating that tanzanite could be found in only two places: Tanzania and Tiffany’s.

Main Factors Affecting the Value of Tanzanite

Each stone’s price greatly depends on its size and quality. Low-grade tanzanite can be had for less than $200 per carat, while richly colored tanzanite in sizes between 3 and 5 carats usually goes for no less than $500 per carat. Exceptional examples of any size are typically priced at $1000 per carat or more.

Tanzanite Can Show Different Colors

This gemstone is pleochroic, which means that it has the ability to show different colors when tilted. Depending on the crystal direction, tanzanite can be more violetish blue or purplish. In many cases, its color looks similar to a sapphire color.

Natural Tanzanite vs. Detect Lab Created Tanzanite

Lab created tanzanite is available and is sometimes marketed as true tanzanite by unscrupulous dealers. It is almost impossible for a layperson to tell the difference between real tanzanite and a well-manufactured fake. If you are hoping to buy or sell tanzanite or tanzanite jewelry, it is very important that you work with a professional unbiased appraiser. This is the best way to ensure that you get as much as possible for your item.

Types of Tanzanite Jewelry

Top quality tanzanite is incredibly rare, but it is used in all kinds of modern jewelry including necklaces, pendants, earrings, bracelets, rings, and charms, as well as cufflinks and shirt studs. Designer pieces containing mixed stones including tanzanite are also popular, and statement pieces are in high demand.
