Generally, blue gemstones of any kind are the most favorable globally simply because the color blue is most worn. This makes Tanzanite even more so popular
because in its truest form, with colors of rich blue and a bit of violet, it’s simply stunning and highly desired. Many people tend to favor such a color because they also relate to it and it can be worn with almost anyone’s wardrobe. It also resembles a very rare Kashmir sapphire, which is yet another reason why people adore it.
Being that Tanzanite was the most exciting find in a gemological sense during the 20th century, it is popular across the globe, but more so within the states. This is because about 70 percent of Tanzanite is sold in the United States. As a matter of fact, between the years 1997 to 1999, Tanzanite was only second to the sales of the sapphire in comparison to colored gemstones. You can find the Tanzanite right alongside rubies, diamonds, emeralds, and sapphires when it comes to their level of popularity.
While popular, it is also rare because of those conditions in which it was formed. Its formation is considered a geological phenomenon and there is only a one in a million chance of it ever occurring again. It was because of the eruption of Mount Kilimanjaro which allowed such crystals to form. With the high levels of heat and pressure, along with a chemical called Vanadium, which is also very rare, this fascinating stone was able to form those millions of years ago.
Although rare, the price of Tanzanite has ranged all over the board. This is simply because of its unstable supply. It is hard to say the specific price range, but it will of course depend on the gemstones size, color and clarity. You will be able to tell if your rare and popular gemstone is indeed Tanzanite by simply observing it properly. Since it is trichroic, meaning three colors, you should be able to see at least two of its colors, if not three when turned in various directions.
Water sapphire is often mistaken for Tanzanite because it also has three colors, but it costs less. An ideal way to determine the difference is to ask a professional jeweler. Another way to check is to observe closed back settings. This is a way in which some try to hide flaws. If your rare and popular Tanzanite is not truly such, you may be able to tell from what is being hidden by the setting.
