A few gemstone, such as Taaffeite and Paraiba tourmaline, are regarded as the rarest on earth. These are rough stones that can be used to create beautiful jewelry pieces. If you want to learn more about these gems, you can check out this article. It’s full of information on them, and you will find out why they are so unique.


Alexandrite is a type of chrysoberyl, a mineral that combines beryllium with chromium. This chemical combination is rare; when it happens, the result is alexandrite. The color of alexandrite changes depending on its surroundings. It can be greenish blue or reddish purple.

Since its discovery, alexandrite has been associated with wealth, royalty, and good fortune. It is also thought to boost self-esteem and emotional well-being.

Although it has become more prevalent in recent years, it is still considered a rare gemstone. There are very few alexandrites on the market.


Taaffeite is a rare gemstone that was initially believed to be a spinel. It was discovered by a gemologist named Richard Taaffe.

Taaffeite is a mineral found in sedimentary carbonate rocks. Other gemstones, such as tourmaline and fluorite, also occur in the same type of rock. The crystal structure of taaffeite is hexagonal.

This gemstone is usually pale but can be red, violet, or green. Purple taaffeite is considered extremely rare. Depending on the color, it can be used as a spiritual boost to increase wisdom and bring emotional balance.

Red beryl

One of the rarest gemstones in the world is red beryl. Red beryl is so rare that one crystal of this mineral is found for every 150,000 gem-quality diamonds.

Despite its rarity, red beryl is always in demand. Its beautiful red color is a favorite among collectors. As a result, many red beryls are found in smaller sizes. A fine, high-quality gemstone can fetch over $20,000 a carat.

Red beryl can be found in several locations in the United States, including the Wah Wah Mountains of Utah, the Thomas Range in Utah, and the Black Range in New Mexico. However, only one locality in the world consistently produces gem-quality red beryl: the Ruby Violet mine in Beaver County, Utah.

Paraiba tourmaline

Paraiba Tourmaline is a beautiful neon blue gemstone. It is one of the most prized investment gems on earth. However, even though it has been found in many different locations, it still needs to be fully understood.

Paraiba tourmalines are rare. They are so rare that they can only be mined in Nigeria and Mozambique. The Brazilian state of Paraiba is also where they were first discovered. They have a distinct copper content that makes them unique stones.

A large variety of colors are available. While most are greenish-blue, they are also available in violet, bluish-green, and neon blue.


Ammolite is one of the rarest natural gems on earth. It is found in only a tiny part of Canada’s Bearpaw formation. Only five percent of all ammonite fossils in the area are suitable for gemstones. The coloration in these gemstones is unique, and the radiance is striking.

Ammolite is composed of layers of aragonite, an extinct shell similar to mother-of-pearl. Aragonite’s structure is made of thin platelets that block light wave diffraction.

The radiance in ammolite comes from the interference of light trapped within the thin platelets. Sometimes, the coloration can shift through the entire spectrum of colors.


If you’re looking for a rare gem, you’ve heard of poudretteite. This pink gemstone is incredibly rare and can cost thousands of dollars per carat.

The stone’s unusual purple-pink color is attributed to manganese. However, it also takes on a wide range of shades because of the trace elements in the rock.

Originally named Scapolite, poudretteite was discovered in the Quebec region of Canada in the 1960s. It was identified as a new member of the osumilite group.

In the mid-1960s, a family-owned quarry near Mont St. Hilaire in Quebec, Canada, began producing poudretteite crystals. These were the only known Poudretteite specimens.


Tanzanite is a trichroic gemstone that displays a variety of blue, violet, and burgundy hues. It is found in the northern part of Tanzania.

A recent report from the Wharton School of the University of Pennsylvania predicts that the supply of tanzanite will be exhausted within 16 years. The stone is one of the rarest gems on the planet.

The stone has a high auction price. Despite its rarity, it is still considered a precious gemstone. It is usually used for necklaces.

There is only one mine in the world that produces tanzanite. It is located in Northern Tanzania, at the foot of Mount Kilimanjaro.
