Top 10 Most Expensive Gemstones

Gemstones are among the most precious natural treasures on earth. People from all across the world have admired them for various reasons throughout history.

In addition to their function as ornaments, they are also recognized for their religious symbolism.

These jewels have historically been prized for their purported therapeutic properties. All gemstones, including diamonds, rubies, and sapphires, exhibit a unique beauty.

There are over 300 gemstones across the globe. This article highlights the top ten most expensive gemstones.

Blue Diamond

The blue diamond is a form of diamond that possesses all of the mineral’s natural qualities, including the stone’s blue hue. They are tinted blue by trace quantities of boron that have contaminated the crystal lattice structure.

Diamonds with strong colors are referred to as fancy color diamonds, which is the name of the subclass of diamonds that includes blue diamonds. Similar to white diamonds, the quality of a blue diamond can range from Flawless to Included depending on its cut grade.

Tanzanite

As its name suggests, tanzanite is only discovered in northern Tanzania, near the foothills of Mount Kilimanjaro. Tiffany & Co. popularized tanzanite by using it in their jewelry. This gemstone has a remarkable deep blue-violet tint compared to one of the sapphires.

Jadeite

Jadeite is the most brilliant, clearest, and rarest gemstone in the Jade family. Jadeite is a pyroxene mineral whose chemical formula is NaAlSi2O6. It has a monoclinic shape. Based on its composition, its Mohs hardness ranges from 6.5 to 7.0. The mineral’s relative density is around 3.4

Black Opal

The most coveted and valuable opals in the universe are black opals. The black body of the stone offers the ideal backdrop for the amazing play of colors. Almost all black opals are mined in the Lightning Ridge region of New South Wales. They are largely viewed as one of Australia’s national treasures.

Red Beryl

Red beryl has been discovered in Utah, New Mexico, and Mexico, although only those extracted in the Wah Wah Mountains of Utah were gem-quality. They display several captivating hues of dark crimson. This kind is among the rarest members of the beryl family, including emeralds.

Emerald

Emerald is a type of mineral beryl tinted green by chromium traces and often vanadium. Beryl has a Mohs hardness between 7.5 and 8. Because most emeralds are strongly incorporated, their toughness (resistance to fracture) is typically low.

Musgravite

Musgravite is an additional gemstone that was identified for the first time in Australia in 1967. In 2005, approximately eight musgravite stones of gem quality were extracted. This demonstrates how uncommon it is. The few discovered contained a spectrum of hues, from translucent olive green to grayish purple.

Taaffeite

Taaffeite is a gemstone named after its inventor, Richard Taaffe (1898–1967), who discovered the first specimen, a cut, and refined gem, in October 1945 in Dublin, Ireland. As a result, this is the only gemstone whose identification was first based on a faceted specimen.

Alexandrite

Alexandrite is a rare, color-changing gemstone. This makes Alexandrite not only incredibly attractive but also valuable. Although they are found predominantly in Russia (where they were discovered in 1833), they are also mined in Sri Lanka, India, and Tanzania. They are usually always spotted in sizes smaller than one carat, which is a curious fact.

Grandidierite

Grandidierite is a unique mineral first identified in 1902 in southern Madagascar. The mineral was given the name of the French explorer Alfred Grandidier (1836-1912), who researched the natural history of Madagascar. The greater their iron (Fe) content, the bluer grandidierites appear.
