Let's talk about a jewel, which Tiffany & Co. named after the country where it was discovered: Tanzanite, a blue and violet stone, consisting of the mineral zoisite. Unlike my favorite, sapphires💙(which usually require greater heat treatment for clarity), tanzanites tend to be more "eye clean," and, they shine more!
Just like diamonds, tanzanites are valued according to the four "c"s: color, cut, clarity, and carat. The most desirable color is a vivid violet-blue, which is what I saw at Tiffany's. Nothing but!

The gemstone was discovered in 1967 by Manuel de Souza, a part-time gold miner, in the hills of Northern Tanzania, and thus far, it is the only place on earth where the rock is found. The government in Tanzania has taken steps to stop the smuggling of tanzanites out of the mining area of the country. A wall completely surrounding the mines was built by the country's army. With regulations in place, the price of tanzanites per carat which now is lower than diamonds and sapphires is expected to climb in the future.

Tanzanite measures a 6.5 - 7 on the Mohs Hardness Scale. (Diamonds are a 10 while pearls rate a 4.) So as with all fine jewelry, caution must be taken not to scratch this brilliant stone.
