Stones by zodiac signs

What is the most expensive stone in the Universe?

Many people mistakenly believe that the limit of the high cost of precious stones stops at diamonds, but in nature there are other, no less beautiful, but rarer minerals, the price of which often exceeds the cost of diamonds.
Below we present to your attention a rating of the most expensive precious stones in the world. A high price is usually determined by a unique combination of rarity, beauty and high demand. The list shows the average cost of high quality stones available on the world market today, however it should be noted that some prices are approximate, as particularly valuable gems are often sold privately, without disclosure to the general public. 19 place: Eremeevit – a rare gemstone, first discovered in 1883 in the south-eastern part of the Trans-Baikal Territory. At first it was mistaken for aquamarine, since the first crystals found were light blue. Over the last century, light yellow and even colorless examples have been discovered, but blue ones are still the most expensive on the gem market. The gem received its name in honor of the Russian mineralogist Pavel Eremeev. It is reliably known that at the moment there are several hundred faceted eremeyevites, the cost of which averages $1500 per carat. 18 place: Blue Garnet – the rarest representative of a number of these minerals, which was first discovered in Madagascar only in the late 1990s. Today, stones of this color are found in Tanzania, Sri Lanka, Kenya, Norway and the USA. Their main distinguishing feature is the ability to change their shade when the lighting changes. So in daylight they acquire blue, indigo and green tints, and in artificial light they become purple or red. Today, the average cost of this high-quality gemstone is 1500 USD. per carat 17 place: black opal – the most valuable of the group of opals, the bulk of which is mined in the vastness of Australia. Other rich deposits are Brazil, USA, Mexico. The color of opals of this type can vary from grayish to black with a rich variety of shimmering tints of all colors of the rainbow. Although today these precious stones are no longer considered as rare as they used to be, they are nevertheless quite expensive. The cost of high quality black opal is approximately $2 per carat. 16 place: Demantoid – a gemstone from the group of garnets of green or yellowish-green color, for a long time known only in collectors’ circles. The main deposits of these gems are located in Iran, Pakistan, Russia, Kenya, Namibia and Tanzania. Every year the popularity of the mineral is steadily increasing, along with which comes an increase in its value. Currently, a carat of top-class demantoid can be purchased on the world gemstone market for $2000. 15th place: Taaffeit – one of the rarest gems in the world, named after its discoverer, Count Eduard Taaffe, who in 1945 accidentally discovered an unusual specimen in a purchased batch of cut gems that he had never seen before. The range of shades of taaffeite can vary from lavender to pale pink. Today, the unique mineral is found in small quantities only in some placer deposits in Sri Lanka and southern Tanzania. The cost of high-quality specimens of taaffeite varies between 2-5 thousand dollars. 14 place: Poudretteite / Poudretteite is a rare pink mineral first discovered in 1987 in Quebec (Canada). It got its name in honor of the Poudrette family, which still owns the same mine in Mont Saint-Hilaire where the first sample was found. Quality stones only began to appear in 2000, when several specimens were found in northern Mogog (Myanmar). Since 2005, the mineral has not been discovered there, and the Canadian deposit has given the world only about 300 stones of varying quality. Depending on the color saturation and purity, the cost of poudretteite can range from 3 to 5 thousand conventional units. 13 place: Musgravit – a close relative of taaffeite, to which it is similar in appearance and chemical composition. It was first discovered in 1967 in Australia’s Musgrave Range. Later, the mineral was found in Greenland, Tanzania, Madagascar and even in the depths of the cold lands of Antarctica. This gem comes in several colors, but the most common are green and purple. Due to the fact that very small quantities of these precious stones have been found throughout history, their price reaches quite expected levels: the cost of a carat of high-quality green musgravite is 2-3 thousand dollars, while for one carat of a purple faceted mineral you will have to pay about 6 thousand conventional units. 12 place: Benitoite – a deep blue gemstone, the only deposit of which is located in San Benito County, (California, USA), where it was first discovered back in 1907. In 1984, it was officially designated as the State Gemstone of the state. On the world market, the average cost of small benitoite weighing 1 carat, of which there is an extremely limited quantity in the world (no more than a dozen), is 4000-6000 USD. 11 place: Sapphire – one of the most famous jewelry stones, in mineralogy and the jewelry industry called corundum. It has a deep blue color; pink, green and yellowish-orange gems are less common. The rarest varieties include blue star sapphire and padparadscha, an orange and red-yellow colored stone. The most famous deposits of these minerals are located in India, Russia, Vietnam, Thailand, USA, Australia, Myanmar, Sri Lanka, China and Madagascar. The rarest and highest quality specimens on the world market can be purchased for approximately 4-6 thousand conventional units per carat. 10 place: Emerald – a gemstone of the highest quality, bright green or dark green. In recent years, Colombia has been named the main deposit of this mineral. Despite the large number of emeralds actively mined all over the world, their prices still remain truly astronomical. Today, pure stones are extremely rare, which, together with their enormous popularity, determines their high cost. A green gem of exceptional quality, weighing approximately 1 carat, sells for more than $8000 on the world market. 9 place: Bixbit – a rare variety of red beryl, until recently known only to some collectors. It is mined exclusively in the American states of Utah (Waho-Waho Mountains) and New Mexico. It is extremely difficult to purchase high-quality red beryl, and the price for a stone weighing about 1 carat is more than 10-12 thousand US dollars. Determining the average cost of this mineral is quite difficult due to the small number of high-quality stones offered for sale. 8 place: Alexandrite is a famous gemstone famous for its ability to change color. In daylight, its color is characterized by bluish-green, dark blue-green and olive green, while in artificial light its iridescence can take on pink-crimson, red, purple or violet-red. The first crystal was discovered in 1833 at an emerald mine in the vicinity of Yekaterinburg. The cost of this precious stone, depending on its quality, can range from 10 to 15 thousand conventional units. 7 place: Paraiba (blue tourmaline) – a beautiful and very rare crystal of bright blue-turquoise color, discovered in 1987 in the state of Paraiba, in eastern Brazil. For a long time, this gemstone was mined in only one place, but today there are already deposits of it in Madagascar and Mozambique. Brazilian blue tourmalines are by far the most expensive representatives of the group – their price is 12-15 thousand dollars per carat, and a truly unique gem of the highest quality can far exceed these figures. 6 place: Ruby is one of the most popular gemstones in the world, known for its rich shades of red: bright red, violet-red, dark red. It is found, like diamonds, on all continents, excluding Antarctica. The main exporting countries are Thailand, Myanmar and Sri Lanka. The most valuable are Asian rubies, especially stones of the “pigeon’s blood” color – pure red with a purple tint. Their limited quantity and enormous popularity make them extremely expensive gemstones. For a carat of high quality ruby ​​on the world market you will have to pay about 15 thousand dollars. 5 place: Diamond – a common mineral that has long remained one of the most expensive and desirable gemstones. The reason for this, of course, is the enormous popularity of diamonds (as cut diamonds are called). Every year the number of manufactured jewelry with these precious stones is rapidly increasing. Industrial diamond deposits are now known on all continents except Antarctica. Currently, a perfectly cut D color diamond sells on average for about 15000 USD. e. per carat. 4 place: Jadeite (imperial) is a green mineral that has long held the status of one of the most mysterious stones on our planet. Today, its main sources are in China, Upper Myanmar, Japan, Mexico, Kazakhstan, Guatemala and the USA. The approximate cost of a carat of high quality jadeite on the world market is 20 thousand dollars. 3 place: Padparadscha (Tamil for “sunrise color”) are pinkish-orange sapphires that were historically mined in Sri Lanka, Tanzania and Madakascar. Nowadays in Sri Lanka there is practically no padparadscha left in its natural form and it is obtained by heating the corundum mineral in a furnace to the desired condition. The last classic (i.e. unheated) padparadscha weighing 1,65 carats was sold in Sri Lanka about 20 years ago for $18. Now padparadscha weighing over five carats is considered collectible and can be valued at up to 30 thousand dollars for each carat of weight. 2 place: Grandidierite is a rare mineral of greenish-blue, greenish-blue or bluish-green color, the first specimen of which was discovered in Sri Lanka. At the beginning of the twentieth century, it was described by the French explorer Alfred Grandidier, who was engaged in the study of Madagascar, on the territory of which the bulk of these minerals are still mined today. Faceted grandidierites today exist in extremely limited quantities – about two dozen. The approximate cost of the unique mineral is more than 30 thousand dollars per carat. 1 place: Red diamond – the most expensive member of its family and also the most expensive gem in the world. In the entire history of mankind, only a few specimens of this mineral have been found and most of them have a very small weight – less than 0,5 carats. The color of a natural red diamond is called purple-red by gemologists. The only deposit of colored diamonds is located in the Argyle diamond mine (Australia), where only a few stones are mined annually. Gemstones weighing more than 0,1 carats typically only appear at auctions where the price per carat is more than one million dollars. Such rare stones are very often declared the property of some country. They are not transferred into private hands, since no one knows how many of them are left. Because of this, a common person can only see these beautiful, rare stones in photographs.

Painite

In 2005, an article about painite appeared in the Guinness Book of Records. According to the book, this gem has the title of the rarest gem in the world. It was found in 1950 in Myanmar by mineralogist Arthur Paynom, who lives in Britain. For quite a long time there were only 2 such stones in the world. However, by 2005, 25 of them had been found.

Tanzanite

This mineral is found almost 1000 times less often than a precious diamond. This is because there is only 1 place in the world where these expensive stones are found. They are extracted from the rocks of the foothills of Kilimanjaro. The quantity of minerals sold is very small. Tanzanite, like alexandrite, can change color depending on lighting conditions and crystal orientation. But its difference from alexandrite is that it has three colors. The mineral turns from blue to purple and then red. According to research, these color variations are mainly due to the presence of vanadium ions in it. We can say that this is the most beautiful, rare gem in the world.
In its natural form, tanzanite is purple or blue in color with yellow or brown areas. Because of this, all such stones are processed using high temperatures so that the yellow-brown inclusions disappear and the stone becomes uniform and has a bright violet-blue color.

Taaffeit

It was discovered completely by accident in 1945 by Count Richard Taaffe among the precious cut gemstones. The Count noticed a crystal among the spinel that was different in color from the others. He asked the laboratory of the London Chamber of Commerce and Industry to carry out his examination. After experiments in the ward, they concluded that this is a new stone that is not yet known to mankind. Until 1945, taaffeites were mistaken for spinel.
That is, taaffeite is the only stone that was discovered after it was processed. After this, for many years only a few such examples existed. Until now, this mineral is almost the rarest precious gem.

Musgravit

Currently, 14 musgravites have been mined around the globe. Musgravite was first found in the Musgrave Mountain Range in 1967 in Australia.
Afterwards, several crystals were found in Madagascar, Greenland, and Antarctica. But only those that were discovered in Australia are considered gems that can be used for jewelry purposes. In 1993, the first rare gem-quality mineral was found. By 2005, there were only 8 gem-quality musgravites available (that is, the stones must be large and transparent to be cut).

Benitoite

This rare blue stone was found at the mouth of the San Benito River in California. Under ultraviolet light, it fluoresces neon blue. This is the most mysterious gem in the world. Although it was first described in the early 20th century, its origins and the composition of substances that give it such rare properties are not yet understood.

Grandidierite

These stones, which have green and bluish colors, can only be found in Madagascar. Although the first grandidierite and the only faceted stone were discovered in Sri Lanka. Just like tanzanites and alexandrites, grandidierites can change colors (pleochroate) from blue to green and white.

Poudretti

The first minerals were mined around 1965 in the Poudrette quarry in Quebec, but it was not recognized as a new type of gem until 1987. Because of this, it was not described in detail until 2003. This may have happened because it is rare for a person to see powdertite not in a photograph.

Eremeevit

This stone was discovered at the end of the 19th century in Siberia. Then several gem-quality crystals were found in Namibia. The largest faceted jeremiahite weighs 60 carats, which is about 12 grams.

Red Beryl

It is also called scarlet emerald or bixbite; this beryl was first described in 1904. Then it was mistaken for another variety of aquamarine or emerald, since it is similar to them in its chemical composition.
Its deposits are the states of New Mexico and Utah. It is very difficult to obtain. Some unscrupulous people passed off rubies with similar qualities as expensive red beryls. But ruby ​​is found 8000 times more often than scarlet emerald. The world’s largest cut red beryl weighs 10 carats.

Red diamond

Red diamond, compared to ordinary diamonds, is a very rare stone.
The largest red diamond is Mussaif, weighing slightly more than 1 g or 5,11 carats.

Alexandrite

Alexandrite is a stone that changes color depending on the intensity of light. It is pleochroic, it changes color if you twirl it in your hand, as it contains a very rare combination of iron, chromium and titanium.
White alexandrite also changes color. In natural daylight, the gem appears blue-green, and in artificial light it appears purple-red.
Alexandrite is part of the same family of rare gemstones as emerald.
