What is the rarest gem in the world?

Everyone has heard the usual list of precious and semi-precious stones that are used by jewelers to make jewelry. Diamonds, emeralds and rubies are names familiar to most people who are not even interested in jewelry. But in nature there are also specimens whose names you won’t even find in every gemological reference book. Many collectors hunt for them for years, and the chance of seeing jewelry with them is so small that its probability is close to zero. We have compiled for you a rating of the rarest gems in the world, which are a real find.

10th place: Eremeevit

This is a mineral from the borate group, which is considered one of the rarest stones. It was named after Pavel Eremeev, who first discovered it in 1883 in the southeastern part of the Trans-Baikal Territory. Initially, it was perceived as one of the varieties of aquamarine, but later it became clear that it is an independent mineral. The first specimens found were light blue in color. But there are also other colors – from completely colorless to greenish and yellow-brown. The most valuable are the light blue stones, which are the least common. The hardness of the stone is 7-7,5 on the Mohs scale. No more than three eremeevites are mined per year, but one cannot say that the price of the stone is astronomical. On average, the price ranges from $1500-2000 per carat.

9th place: Taaffeit

A rare oxide class mineral that was discovered by Earl Richard Taaffe in Dublin. This happened in 1945, when, among a large number of cut stones, the count discovered one specimen that was completely different from the others. Initially, it was perceived as one of the varieties of spinel, but nevertheless it was decided to send the sample for examination. It was first examined at the London Gem Laboratory, where it was discovered that it was a mineral that had not been seen before. The stone was then transferred to the Mineralogical Department of the British Museum, where a more thorough examination was carried out. It was found that the chemical composition of the mineral is something between spinel and chrysoberyl. The hardness of the stone is 8 on the Mohs scale. Color ranges from colorless to green and pinkish. Found only in Sri Lanka and two deposits located in China. Formally, it is considered a semi-precious stone, but the great rarity of the mineral (1 taaffeite per 1 million diamonds) allows it to be classified as precious. This is evidenced by its price – about $35 per carat.

8th place: Poudretteite

A very rare stone that was discovered in the form of small crystals in the 1960s in Canada, in the Mont-Saint-Hilaire region. It was named after the Poudrette family, who operated the quarry where the mineral was originally found. The main feature of the stone that arouses the interest of collectors is the effect of pleochroism (the mineral changes color depending on the direction of the axes – from colorless to purple-pink). Later, stones began to be discovered in other places. In 2000, a 9,41-carat mineral was found in Myanmar, but since 2005 they have not been discovered in that country again. Today, the main and only supplier of powderetteite is Canada. Its price is $3000-5000 per carat, depending on the purity of the stone and color saturation.

7th place: Musgravit

This is a mineral that is similar in chemical composition to taaffeite. The first specimen was discovered in 1967 in southern Australia. Then several stones were found in Madagascar, Greenland and even Antarctica. The mineral comes in a variety of colors, but green and purple stones are the most common. According to some sources, there are only 8 faceted musgravite crystals in the world today (according to other sources, there are about 20). The cost of the stone depends on the color: 1 carat of green musgravite costs about $2000-3000, and 1 carat of purple stone costs about $6000.

6th place: Grandidierite

This is a rare mineral that has a greenish-bluish tint. It was first discovered in 1902 on the island of Madagascar. Its main feature is the effect of trichroism, i.e. the mineral radiates three colors at once: colorless, blue-green and almost completely black. More than 120 years have passed since its discovery, but during this time only 20 stones were found that were suitable for cutting. Despite its relatively high hardness (7,5 on the Mohs scale), it is very brittle and therefore difficult to process. This exclusivity directly affects its price: for specimens of average quality you will have to pay about $3000, and 1 carat of premium grandidierite can cost about $40-000.

5th place: Benitoite

The deep blue stone was discovered in 1906 in San Benito County, located in the US state of California. Its peculiarity is that under the influence of ultraviolet radiation it glows white-blue. Benitoite is found only in California and was designated the State Gemstone of that state in 1984. Most often there are specimens weighing about 1-2 carats, the cost of which is about 5000-6000 dollars. Large benitoites are not sold for sale, but are kept in state museums: 2 stones weighing 6,53 and 7,83 carats are in the American Museum of Natural History and the Smithsonian Institution.

4th place: Majorite

This is a purple variety of garnet that is very rare in nature. The unusual color is formed due to the enormous pressure on the stone underground at a depth of 400 kilometers. The mineral was named after physicist Alan Major, who studied it and the formation of garnet rocks under extremely high pressure. The first specimen was discovered in 1970 in the Koorara meteorite in Western Australia. There are no majorite deposits in nature, i.e. it is found in different countries only in single copies. Interestingly, the last find dates back to 2004 – the stone was found in France. There is a theory that if people are able to explore the Moon and Mars, the price of majorite will go down sharply. This is explained by the fact that these celestial bodies have the most favorable atmosphere for the formation of “purple garnet”. It is difficult to talk about the price for majorite, because all found stones are immediately put up at auctions. So far, the most expensive specimen weighing 4,2 carats was sold for $6,8 million.

3rd place: Painite

A borate mineral that was first discovered in 1956. Named after its discoverer, mineralogist Arthur Payne. The color ranges from orange-red to brownish-red, making it similar to topaz. After its discovery, for many years only 3 small crystals existed. In 2005, painite was included in the Guinness Book of Records as the rarest gemstone. But today he has lost this title, because in 2006 another deposit was discovered in the north of Myanmar, so the amount of minerals has increased. Unfortunately, the new deposit did not produce gems of the same high quality as those previously mined. Today, already discovered painite crystals are in private collections, as well as several museums and institutes. There is no information about the number of cut stones, so any high-quality specimen literally flies off the market. There is simply no upper limit on cost.

2nd place: Red beryl (bixbite)

This is a very rare stone that was discovered by mineralogist Maynard Bixby, which is why it was originally called bixbite. But most often the name “red beryl” is used, so as not to confuse it with another mineral – bixbyite. It is mined in only one place – the Waho-Waho Mountains, located in Utah. The state’s Geological Survey has announced that for every 150 gem-quality diamonds, only 000 red beryl is found. The average price for 1 carat is about $1, but it is very difficult to buy a stone because collectors literally hunt for it, so most specimens simply do not reach auctions.

1st place: Red Diamond

It is difficult to say whether it can be called the rarest, but the most valuable stone in the world is undoubtedly the red diamond. Very few examples have been found, with most of them being very small – less than 1 carat. The only deposit is located in the Argyle mine, located in Australia. The price is astronomical – from 1 million dollars per carat.

What other rare gems are there?

  • Padparadscha sapphire. These are pinkish-orange stones that were mined in Sri Lanka, Madagascar and Tanzania. Very rare today – the last stone, weighing 1,65 carats, was sold in Sri Lanka for $18 more than 000 years ago. Today, the characteristic color of a mineral is obtained by heating, but such stones are noticeably cheaper than natural minerals.
  • Paraiba tourmaline. This is a mineral of rich blue-turquoise color, which was discovered in 1987 in Brazil – in the state of Paraiba. The mineral was then discovered in Mozambique and Madagascar. In our catalog you can see jewelry with Paraiba tourmaline.
  • Alexandrite. Among the rare ones is alexandrite, which is capable of changing its color under different lighting conditions (from green in natural light to red in artificial light). You can appreciate the beauty of alexandrite in luxury jewelry from famous Russian manufacturers.

Rarity always means exclusivity. And when it comes to stones, this becomes even more obvious. The amount of minerals is gradually decreasing, which is very frustrating. But their price is growing exponentially, so buying jewelry with a rare stone can be a good investment in the future. This is the choice of those who think not only about today, but also about tomorrow.

In our society, there is a widespread stereotype that only precious stones have real value, and jewelry and decorative ones are associated with costume jewelry, at best high-quality. However, a comparison of price levels on the natural minerals market completely refutes this stereotype. For example, 1 carat of a low-quality diamond with many inclusions can cost 10 times less than 1 carat of a garnet with a rare rich color and high transparency, despite the fact that the diamond is a precious stone and the garnet is a jewelry (semi-precious) one.

The rarity of jewelry stones is a complex concept that combines originality, exclusivity and the effort put into mining and cutting. In addition, the place of origin, the conditions under which the mineral was formed, and the qualitative characteristics of the specimen: color, clarity, cut and carat weight play an important role in the concept of “rarity.” The rarer the stone, the more expensive and popular it is among collectors and connoisseurs.

The rarest jewelry stones are true natural phenomena that are found in single copies, and their cost reaches astronomical amounts. Aesthetic value and geographical exclusivity turn such stones into incredible treasures that few manage to acquire. Each crystal is a piece of history with unique beauty. Glitter, play of light, geometric precision – all this is only a small part of what is hidden in this small miracle of nature.

Let’s talk about the six rarest gems, their characteristics and the reasons for this status. The Emporium Gold salon offers you to buy jewelry from famous brands at a price of up to -50% of the boutique price. The authenticity of the products and the characteristics of the precious stones are confirmed by a certificate. Free delivery within Russia will be a pleasant bonus.

Many have never heard of the Grandidieret, let alone seen one. The first specimen of this silicate mineral, the rarest gemstone in the world, was discovered in 1902 in the south of Madagascar and named after the French explorer Alfred Grandidier. Soon, small deposits were discovered in other parts of the world: in Sri Lanka, Malawi, Antarctica, Australia and Namibia. The peculiarity of the mineral is trichroic pleochroism. Depending on the viewing angle, the stone shows three shades: dark green, dark blue-green and light light yellow. The most desirable and rare color is soft neon blue.

Despite the fact that grandidierite has been known to mankind for 120 years, this mineral has gained popularity only in recent decades. Limited availability has led to a surge in demand from collectors and jewelry designers. Today there are about twenty impressive cut specimens on the planet, so if anything surpasses the beauty of grandidierite, it is its price. Jewelry-quality samples weighing 1-2 carats of bright color, good transparency with a strong pleochroism effect cost 20-25 thousand dollars per carat.

Red beryl (2 photos)

Red beryl, also known as bixbite or red emerald, is 1000 times rarer than gold. The vibrant crimson red hue is unlike anything else in the world of gemstones. First discovered in Utah in 1904, the mineral was not much different from the usual emerald or aquamarine. However, red beryl is recognized as an independent mineral and is considered the rarest among beryls. The Ruby Violet Mine in Utah is famous for its incredible finds of red beryl. Although mining has been taking place here for 120 years, stones of such rarity always cause delight and surprise among experts. Small deposits of red beryl have also been discovered in other countries: Russia, Mexico, Brazil and Madagascar. But the inaccessible nature and complex geological conditions of these deposits make the mining of red beryl extremely difficult and dangerous.

Most red beryl specimens found are only a couple of millimeters in size and are too small to process. Those crystals that were cut weigh less than one carat. Stones weighing 3-4 carats are considered an exception to the general pattern. The overwhelming majority of red beryls found do not even have time to reach the jewelry market, ending up in private collections. Prices for red beryls reach up to 20 thousand dollars per carat.

Diaspora (2 photos)

Diaspore, otherwise known as zultanite or reign, is a relatively rare mineral belonging to the group of aluminum hydroxides. The name “diaspora” is of Greek origin and means “scattered”. This is because this mineral often occurs as scattered crystals in rocks. It is valued for its extraordinary ability to change color depending on lighting conditions (pleochroism): from yellowish-green to pinkish-red or purple-red.

Diaspores were first discovered in 1801 in Russia, and today the stone is mined all over the world, including Brazil, China and the USA. But the main commercial deposits are located in Turkey and belong to Murat Akgun, who in 2005 introduced the new mineral Zultanite to the world. Marketing efforts to promote zultanite were successful, and the gem gained recognition and popularity among connoisseurs of rare and unusual jewelry stones. The patented name “Csarit” emphasizes the Turkish origin of the stone. Although “Zultanite” and “Tsarit” are brand names, the mineral itself is still known as a diaspora in the scientific and mineralogical communities.

Features of diaspora that increase the cost of the stone are its immunity to additional processing by heating or irradiation (refinement) and loss of up to 98% of the weight of the crystal during the cutting process. Faceted examples weighing 5 carats are rare. The cost of jewelry-quality diaspora starts from 1 thousand dollars per carat. Green crystals with flashes of purple-red hues are more prized than others.

Tanzanite is a “young” jewelry stone, discovered only in 1967. At first, the found crystal was mistaken for glass, then for sapphire, and only after careful examination it turned out that we were talking about a new variety of the mineral zoisite.

Today, tanzanite is mined commercially in only one area of ​​the world – the Merelani Hills in Tanzania. The color of the stone varies from bright blue to purple. Most specimens exhibit the optical effect of pleochroism: color changes when illuminated from different angles. The American jewelry company Tiffany & Co. began promoting the gem, renaming blue zoisite to tanzanite in honor of the gem’s homeland. In addition to its rarity and unsurpassed color, the stone gained popularity thanks to Tiffany’s smart marketing policy. Tanzanite became the constant companion of actress Elizabeth Taylor and “played” the role of the blue diamond “Heart of the Ocean” in the film “Titanic.”

Reserves of the stone are rapidly decreasing, so it is unknown which nugget will become the last natural tanzanite on Earth. Rarity and exclusivity make this mineral extremely expensive and in demand for investment. At auctions, the starting price of the stone starts at 1,2 thousand dollars per carat, and there is no upper limit.

Most people are not even aware of the existence of this stone, which was first discovered in 1907 in California, USA. Initially mistaken for sapphire due to its blue color, benitoite, after careful research, received the status of a separate type of mineral. Since 1985, benitoite, called “Blue Diamond”, has been recognized as the official product of the State of California. Benitoite has a unique shade of blue—a vibrant, electric sapphire blue—and strong dispersion. The stone is capable of splitting white light into spectral colors, which creates a fiery glow within the crystal.

Since its discovery, gem-quality benitoite has been mined in only one location in the world: San Benito County, California, after which the stone is named. Later, this mineral was discovered in other deposits, but its quality is not comparable to that of California.

Today, reserves of American benitoite are almost exhausted, and the cost of already mined crystals is constantly growing. Finding jewelry with benitoite is extremely difficult. Mostly jewelry with these crystals is made to order. Unprocessed specimens of benitoite are often sold as collectibles or used in museum displays. The cost of 1 carat of bright blue pure benitoite reaches 4 thousand dollars, and specimens over 3 carats are sold exclusively through auctions.

This unusual two-color mineral combines the name and color of amethyst and citrine. It is also known as “Bolivianite” because it occurs naturally only in the Anaya mines in eastern Bolivia. Ametrine is mined in small quantities in Brazil and even in mines in Siberia. But the stones found in these deposits are much paler and have virtually no value.

The color play of ametrine crystal amazes with its unpredictable spectrum. The palette of shades gradually changes from purple to lemon yellow. Some ametrines exhibit flashes of green and orange. The mineral is easy to cut and cut, so it is widely used in all types of jewelry.

It would seem that due to the rarity of natural specimens, the price of one carat of ametrine should be high. However, natural ametrine costs $100 per carat. Valuable samples with rich colors cost from $200.
