A wide range of minerals, rocks, and organic components make up gemstones. Here is a list of some of the minerals and rarest gemstones that are undoubtedly rarer and more valuable than diamonds out of the more than 2000 minerals and more than 300 gemstones that are currently known to exist.

Some of the rarest jewels in the world can be produced through changes in impurities, assembly, pressure, temperature, and crystal structure substitutions. We provide a selection of the rarest jewels in the list below. 

Minerals can be classified into gemstones based on their makeup, chemical, refraction, crystal structure, and optical properties. The kind and extent of flaws in a mineral or stone can establish its worth and related rarity.

1. A Blue Diamond

Blue diamonds are the priciest gemstones in the world. They are not only uncommon, but they also have a remarkable shine. Perhaps the most well-liked gemstone among humans is this one. 

The biggest vivid blue diamond ever put up for auction is the Oppenheimer blue diamond. With a weight of 14.62 carats, it sold for 57.5 million dollars or 3.39 million euros per carat.

2. Red Diamond 

The red diamond, which costs more than $1–2 million per carat, is the second most rarest gemstones after the diamond that we highlighted above. Less than 30 red diamonds have been discovered globally, with the majority weighing less than half a carat. 

Although it may seem that impurities are the source of gold and the red colour diamond, the crystal lattice’s plastic deformation is what gives the colour its original hue. This stone only has a single deposit, known as The Argyle Mine, and it’s in Australia. 

Acquired in 2011 for $8 million, the renowned Moussaieff red diamond weighed 5.11ct. As of now, it is the world’s largest red diamond found. € 864,790 – € 1,727,940 ($1,000,000 – $2,000,000) per carat on average

3. Azure Garnet

A very expensive and uncommon gemstone is blue garnet. Madagascar, the US, Turkey, and Russia are the only countries with significant deposits. When exposed to sunshine, blue garnet appears blue-green; when exposed to artificial light, it turns purple. 

Approximately 1.5 million dollars is the cost of a single carat. The most costly blue garnet stone, weighing 4.2 carats, sold for $6.8 million in 2003. The average cost per carat is €1,296,060 ($1,500,000).

4. Taaffeine 

Highly uncommon and frequently mistaken for spinel is taaffeite (BeMgAl4O8). Remarkably, the gemstone was first found in Dublin, Ireland, in 1945, completely polished and cut.

Inspection revealed that the mineral was actually a brand-new, unidentified gem, despite the gemstone’s incorrect designation at the time, which read “spinel.”

Taaffeite and spinel vary primarily in that the former has a twofold refraction. Tanzanian and Sri Lankan alluvial deposits contain the gem. The average cost per carat for premium material is EUR 30,249 ($35,000) per carat.

5. Jadeite: Each Carat Costs € 17,295 

Despite its look, jadeite is the most valuable gemstone in the world and tops our list. The most costly and exquisite type of jade is this gemstone. This translucent dark green stone is substantially more valuable than other forms of jade since it is much rarer.

6. Serendibite 

Found in Sri Lanka in 1902, serendibite ((Ca,Na)2(Mg,Fe2+)3(Al,Fe3+)3) is an incredibly uncommon gemstone and mineral. With several calcium, boron, aluminium, magnesium, and other side branches, this inosilicate has a complicated chemical formula.

The Mogok region of Myanmar is home to the recently found serendibite. The average cost per carat is EUR 15,571 ($18,000).

7. Diamond 

The diamond (C), the main feature of most engagement rings, is the one we’ve all heard of. Since pure carbon makes up the majority of a diamond’s chemical composition, it is clear why they are incredibly strong and durable.

Kimberlites, which have cooled over a period of one to three billion years, contain types of diamonds. The average cost per carat is € 12,961 ($15,000).

8. Ruby

At € 12,961 per carat, rubies are among the most sought-after gemstones worldwide owing to their striking red hues. It is a member of the corundum family, and its red color results from the presence of chromium oxide.

9. Alexandrite 

The Ural Mountains are home to the chrysoberyl type known as alexandrite (BeAl2O4). The impurities of iron, titanium, and chromium that are present in alexandrite distinguish it from chrysoberyl.

Alexandrite is one of the few color-changing gemstones available, becoming red in incandescent light and green in sunlight. This is one of the changing gemstones that you may purchase.

10. Red Beryl – Rarest Gemstones

Beryllium, aluminum, and silicate make up the mineral red beryl (Be3Al2Si6O18). Pure beryl is colorless in natural gemstone ; it gets its color from traces of other elements.

A carat of Padparadscha sapphire costs €6,919. Sri Lanka, Tanzania, and Madagascar are the main locations for padparadscha sapphires, which are incredibly uncommon. Pronounce it pad-pah-raj-ah. One of the colors that attracts collectors the most about this stone is the unusual mix of pink and orange.

11. Musgravite 

Musgravite is an aluminum oxide that contains different amounts of zinc, iron, and magnesium. First found in the Australian Musgrave Ranges in 1967, musgravite (Be(Mg,Fe,Zn)2Al6O12) is a mineral.

One of the most well-known gemstones is sapphire. Vietnam, India, Russia, Thailand, the United States, Australia, China, Myanmar, Sri Lanka, and Madagascar are the countries with the most well-known sapphire reserves.

The stone is blue, but it can also be pink, green, or yellow-orange in hue. The average price per carat for medium-toned stones ranges from €3,458 to $5,188 ($4,000 to $6,000).

12. Benitoite: Each Carat Costs €3,458. 

Benitoite (BaTiSi3O9) is a silica, titanium, and barium g-stone with a dazzling blue color. When hydrothermally altered serpentinite cools down to its final stage, benitoite forms.

The name of this unusual gemstone comes from its location in San Benito County, California. Benitoite exhibits intense fluorescence and a vivid blue hue.

13. Black Opal

As one of the rarest gemstones overall, black opal is typically the rarest and most well-liked variety of opal. Australia’s Lightning Ridge, in New South Wales, is the basic source of the world’s supply of black opal.
