There are many reasons to buy tanzanite, whether to celebrate a December birthday, to commemorate a 24th wedding anniversary, or simply to enjoy the gemstone鈥檚 rare, vibrant blue. It even serves as a less expensive substitute for sapphire.

Most tanzanite on the market today gets its blue color from heat treatment, which minimizes the stone鈥檚 natural brown hues. Treated tanzanite has become the norm, so although it鈥檚 undetectable, it鈥檚 usually assumed.

Generally, tanzanite follows the same value parameters as diamonds. Color, of course, is tanzanite鈥檚 most prized trait, especially when it鈥檚 deeply saturated blue with violet hues. Paler shades are less expensive.

Tanzanite is pleochroic, which means it displays different colors from different angles. The cut significantly influences the color, which determines the price. Cutting tanzanite to emphasize the blue may waste more of the rough, but because this color is more valuable than violet, the cutter may choose a small fine-colored blue gemstone over a larger violet one.

Most faceted tanzanite weighs less than five carats. Gemstones heavier than 50 carats are rare, although The Smithsonian Institution鈥檚 collection includes a faceted 122.7-carat tanzanite. The world鈥檚 largest rough tanzanite weighed 16,839 carats.

Because tanzanite gems are only found within a few square miles in Tanzania, their price and availability can fluctuate sharply, depending on what happens there.

Although it doesn鈥檛 have a long history of admiration like some gemstones, tanzanite didn鈥檛 take long to rise through the ranks. Between its exclusive origin, finite supply, and intense blue beauty, tanzanite continues to grow in popularity.
