what is the difference between tanzanite and amethyst

Tanzanite and Amethyst are two of the most popular gemstones in the world. Both are beautiful, and both have a rich history. But what is the difference between them? This blog post will explore the differences between Tanzanite and Amethyst and their similarities. We will also discuss the history of both stones and their mined locations. So, what is the difference between Tanzanite and Amethyst? Let’s find out!

What Is Tanzanite?

Tanzanite is amongst the unique gemstones to come from the earth. It is a variety of zoisite, calcium aluminum silicate, and blue in color. Tanzanite was first discovered in the northern part of Tanzania, Mererani, near Mount Kilimanjaro in 1967. 

Since then, the gemstone has never been found anywhere else globally, thus earning the country name. Over time, the stone gained popularity because of its clarity and rarity.

What Is Amethyst?

Amethyst is a purple variety of quartz and owes its color to iron impurities. The name comes from the Greek word Amethystos, meaning “not intoxicated,” as the ancient Greeks believed it would protect against spiritual intoxication. The Amethyst was sacred to the god Dionysus, who is often depicted wearing a wreath of amethyst leaves.

The birthstone for February, Amethyst, is found worldwide, but some of the best gem-quality amethysts come from Brazil. This gem discovery in other parts of the world made it possible for jewelers to cut it in several shapes and sizes. However, this lowered the value of amethysts overall.

Amethyst is still a relatively affordable gemstone, especially when compared to diamonds, emeralds, and rubies. It is the most popular purple gemstone and can be found in various jewelry styles.
