What is the name of the most expensive stone?

The most expensive gemstone in the world One of the most unique gemstones in the world, the flawless blue diamond was awarded the title of the most expensive gemstone in the world in 2007.
We invite you to read about ten of the most amazing gems, each of which is a kind of work of art.
1. Kohinoor, the crown jewel of British rulers
The Kohinoor is a 106-carat diamond that was once the largest diamond in the world. Previously owned by Indian rulers, today it is in the hands of the British royal family and is part of the crown jewels. When Kohinoor came into the possession of the British royal family, it weighed 186 carats (37 g). Prince Albert specifically looked for a jeweler with an excellent reputation and personally went to Holland to entrust the processing of the diamond to a certain Mr. Cantor. He got to work, and after some time the diamond was presented to Queen Victoria.
The diamond became part of the royal crown and was last worn by the Queen Mother during her coronation ceremony when she became Empress of India.
2. Millennium, a sapphire the size of a football
The size of a football, the Millennium Sapphire is a jewel carved with portraits of famous historical figures. The sapphire is currently selling for $180 million, but the buyer must place the 61,5-carat wonder where people can look at it. Created by Italian artist Alessio Boschi, the Millennium Sapphire is a tribute to human genius. There are 134 portraits carved on it, including Beethoven, Michelangelo, Shakespeare, Albert Einstein and Martin Luther King Jr. Millennium is now owned by a consortium of investors led by Daniel McKinney. Over the past 15 years, the sapphire has been on public display only twice – at the Oscars in 2002 and on the Sapphire Princess during its maiden voyage in 2004. A 28-centimeter sapphire was found in Madagascar in 1995. In its natural form, it weighed about 90 thousand carats, but lost about a third of its mass during the processing process, which lasted two years and was completed in 2000.
3. Don Pedro, the world’s largest aquamarine
The world’s largest processed aquamarine is in a museum in Washington next to the Hope Diamond and Marie Antoinette’s earrings. Mined in Brazil in the 1980s, the pegmatite is named after the first two Brazilian emperors. Aquamarine Don Pedro occupies a place of honor in the National Museum of Natural History at the Smithsonian Institution.
The blue-green gemstone, reminiscent of an obelisk in shape, was created by the famous German jeweler Bernd Munsteiner, known as the “father of carved fantasies”. Don Pedro is 35,5 cm tall and weighs 10 carats (or two kg).
4. The world’s largest pearl
On November 21, 2010, the world’s largest luminous pearl was shown to the public in the Chinese province of Hainan. The pearl, weighing almost six tons and with a diameter of 1,6 m, is estimated at two billion yuan ($301) – in China, pearls are valued higher than diamonds.
The stone, composed primarily of fluorite, glows green in the dark. It took almost three years to give the stone a perfectly round pearl shape.
5. Graff Pink – the world’s most expensive pink diamond
Lawrence Graff is the world’s largest gem dealer. In 2010, his reputation was confirmed by the purchase of a stunning rarity – a pink diamond weighing 24,78 carats. Graff owns five luxury mansions in England, France, Switzerland and New York, as well as a personal Mediterranean yacht, a diamond mine outside Johannesburg and half a dozen private properties in Mayfair.
A flawless pink diamond set a new price record at Sotheby’s auction: bids continued to rise, the situation was tense NSSupreme Intelligence (347287) 8 years ago The stakes continued to rise, tensions grew, and the diamond eventually went to Britain’s 36th richest man for $45 million, the most ever paid for a piece of jewelry. 6. Divine Essential Carolina – the largest Paraiba tourmaline NS Supreme Intelligence (347287) Montreal financier Vincent Boucher is the owner of the Divine Ethereal Carolina, a Paraiba tourmaline weighing approximately 192 carats. The stone is valued at between $25 million and $125 million, a world record price for Paraiba tourmaline. Paraiba tourmaline is one of the rarest gemstones in the world. The stones are named after the Brazilian region where they are mined, and that is where the vast majority of these stones are found. For every 10 diamonds found, there is one Paraiba tourmaline, and in total, only 50 kg of these gems have been mined to date. Nikitok10 DemaMaster (1336) 6 years ago This is not a natural alexandrite, unless you got it from a museum. A natural alexandrite of this size is EXTREMELY rare and considering that a good quality alexandrite with excellent color change goes for about $60,000 a carat, no way this is a real one. It’s very very hard to find natural alexandrites, even man made ones are very expensive. If by some luck u do find a real alexandrite, buy it, as it’s a great investment. They are becoming more rare every year and the price u pay today just may double by next year. It is the rarest stone in the world and much more beautiful than the most flawless diamond. Nikitok10 Dema Master (1336) Everybody has diamonds but I bet nobody u know has or has ever seen a true natural alexandrite. It’s widely known that 90% of all the jewelers in the US have never even seen a natural genuine alexandrite. THAT is how rare it is. And the few collectors that have them are not parting with them at any price. I know. Lisa Lisa A year ago And you are all poor natives and fools! Precious and semi-precious red stones have always been considered the most valuable and one of the most desirable. Since ancient times, the color red has been associated with love and passion; it also symbolizes power. Jewelry with red stones is worn when you want to attract attention and be in the center of events. Please note that the rich red color of the stone can not only attract attention, but also have an overwhelming effect on the interlocutor; it is a very authoritarian color. Psychologists recommend choosing softer tones of red if you want to win someone over.

Shades of red in gemstones

  • red (Red);
  • Pinkish Red;
  • orange-red (Orangy Red);
  • Purplish Red;
  • reddish purple (Reddish Purple).

These color groups are further divided into gradations according to intensity, which are determined by the overall sensation of color depending on the lightness and saturation of the color of the stone:

  • average (Medium);
  • strong (Strong);
  • intensive (Intense);
  • saturated (Vivid);
  • deep (Deep);
  • dark (Dark).

Lighter gradations (Pastel, Very Light, Light) in this system are not used to describe the color red, because will already refer to variations of pink color.

With this in mind, the color of the stone will eventually be designated, for example, as “Medium Pinkish Red” or “Intense Red”. Also, for the main jewelry stones, these color gradations in our company have visual standards in the form of specially calibrated photographs of cut stones. For all red stones, the same principle applies: the brighter the color of the stone and the closer it is to pure spectral, the more expensive it is. Therefore, the most expensive stones will be those that have an intense and rich red color. Thus, abroad, the top colors of red stones are often referred to in commerce as “Vivid Red” (“rich red”). Additional orange and purple hues may reduce the cost for some stone varieties.

Basic Red Gems

Let’s look at the most important red gemstones that we also work with. We have arranged these stones in descending order of their Gemlovers conditional rating, which takes into account the rarity of the stone, its cost, beauty and hardness.

1.Red diamond

Natural red diamonds are considered the most expensive gemstones in the world. They are very rare and are of great interest to collectors and investors. Their color is associated with disturbances in the crystal structure of diamond. Often the color is distributed unevenly in these stones. The mass of cut red diamonds is usually represented by specimens of only up to 0,5 carats. During all this time, only a few dozen stones were mined. Note that the hardness of diamond is the highest of all precious stones – 10 on the Mohs scale.

According to the Gemological Institute of America (GIA) system, red diamonds are classified into the following colors with shades: Red, Brownish Red, Brownish Orange Red, Brownish Purplish Red, Orangy Red, Purplish Red, Purple Red, Brownish Purple Red. For red diamonds (unlike other colored diamonds) there is only one gradation of color intensity – Fancy. Mostly on the world market, the color of red diamonds is represented by stones of weak saturation, with purple or brownish tints. Thus, the rarest and most valuable color is Fancy Red, i.e. without additional shades.

Our company can find red diamonds to order for you, as well as make jewelry of any complexity with them. These stones will be sourced from collectors, reputable suppliers and auctions. We will analyze the market for them and provide the best offers. When purchasing such a stone, we provide a certificate from the reputable GIA laboratory. It contains information about the natural origin of color, the weight of the stone, characteristics of color and purity, and cutting parameters. In jewelry, small red diamonds usually take center stage in white gold rings, which are often heavily studded with pink and colorless diamonds.

2. Rubin

Ruby is a gemstone, a type of corundum with a deep red color. Rubies can be colored with shades of pink, purple or orange. In the trade, the term Pigeon’s Blood may be used to refer to the most valuable bright red color of a ruby. This is a Vivid Red color with medium to high UV glow. Some of the best colored rubies are mined in Myanmar (Burma). Burmese natural rubies are an established brand in the jewelry world. Unrefined “pigeon blood” rubies from Burma are the most valuable. The best quality Burmese rubies can fetch over US$1 million per carat at auction. Today, rubies from Mozambique are found on the world market more often than others; their color can also be very beautiful, but they cost several times less than Burmese ones.

In Russia, there is a classification of ruby ​​colors according to specifications, which distinguishes 2 color subgroups “a” and “b” depending on the degree of manifestation of color shades, which in turn are divided into 5 color groups, taking into account possible combinations of lightness and saturation. The most expensive color according to it will be “1a” – red (as well as red with a weak violet and orange tint) of medium lightness and strong saturation.

At Gem Lovers, to classify the colors of rubies, we have identified 3 main colors with a shade:

  • red (Red);
  • slightly purplish red (Slightly Purplish Red);
  • Purplish Red.

Each of these colors is divided into the following gradations according to intensity:

  • average (Medium);
  • intensive (Intense);
  • saturated (Vivid);
  • deep

Very dark natural rubies, regardless of shade, all fall into the Dark Red gradation. If the color of the stone is lighter than average intensity, then according to our system it will be classified as pink sapphires, and not rubies.

We recommend our clients to choose rubies in the “Intense Red” and “Vivid Red” color gradations. Please note that almost all rubies are enhanced by heat treatment to remove additional tints and improve clarity. Visually pure and, at the same time, without refining, bright red rubies are very rare and are highly valued even in small quantities.

3. Red spinel

Spinel is a rare and beautiful gemstone that comes in a wide range of colors. Large gem-quality spinel is rare and therefore especially valuable. The high hardness of spinel (about 8 on the Mohs scale) allows it to be used in all types of jewelry. The most valuable is the bright red spinel. Over the past few years, the price of rich pink-red spinel from Tanzania has increased greatly. Spinel has been known as a jewelry stone since ancient times. Previously, red spinels could not be distinguished from similar-looking rubies and were valued equally highly. The imperial crowns of Russia, Great Britain, France and Germany are decorated with spinel.

In Gem Lovers, for the red tones of spinels, we have identified 4 primary colors with a tint:

  • orange-red (Orangish Red);
  • pinkish red (Pinkish Red);
  • red (Red);
  • Purplish Red.

In terms of intensity, these reddish colors are divided differently due to differences in the transitions to pink, but the main gradations are as follows:

  • intensive (Intense);
  • saturated (Vivid);
  • deep

Very dark red spinels, regardless of shade, all fall into the Dark Red gradation. And light (Light) and medium (Medium) will already belong to pink spinels.

4. Tourmaline rubellite

Rubellite is the so-called “semi-precious” stone of red shades, one of the most expensive varieties of the mineral tourmaline. Sometimes rubellites with a slight purple tint are found. From Latin the name of this stone (lat. rubellus) is translated as “reddish”. Rubellites often contain inclusions, so the approach to assessing their purity is not very strict, and their color is in the foreground. The brighter the rubellite, the more expensive it is. Rubellites are very popular today, and they can be found in the collections of many world jewelry brands.

According to our system, most rubellites are purple-pink in color. We highlight red colors only in darker tones in the “Deep” gradation, these are two colors with a tint:

  • Purplish Red;
  • slightly purplish red (Slightly Purplish Red);

Pure red color without purple tint is extremely rare in tourmalines.

5. Red garnet

Garnets are a large group of minerals, including varieties of different colors. The most famous are red garnets. Pyrope is a “semi-precious” stone, its color ranges from fiery red to dark red, sometimes brownish. The name of the mineral is translated from Greek. “pyropos” – fire-like. In jewelry it is often represented in small specimens of a thick dark color. Almandine is a natural red garnet with a purple tint, less often dark brown. Its name is associated with the city of Alabanda in Asia Minor. Good quality specimens are more expensive than pyrope. Rhodolite is a commercial variety of garnet, intermediate in chemical composition between pyrope and almandine. The name of this “semi-precious” stone comes from the Greek words “rhodos” (rose) and “lithos” (stone). Its color ranges from pink to pinkish-red, violet-red. Nowadays, in commerce, red garnets are often called rhodolites, which is not correct. Also, the orange-red color can stand out from other varieties of garnet – spessartine and hessonite, which usually have orange tones.

If we exclude the reddish-purple garnets and spessartines with hessonites, then the more classic red garnets in Gem Lovers are divided into two categories by color:

  • red (Red);
  • Purplish Red.

And according to intensity they are divided into:

  • average (Medium);
  • strong (Strong);
  • deep (Deep);
  • dark (Dark).

Most red garnets are dark in color, but we try to find rarer and brighter specimens for our clients.

6. Red zircon

In nature, cut-quality zircons come in a variety of different colors. Zircons with reddish tints are quite rare. For orange-red specimens there is a proper name “hyacinth”, but it is already quite outdated and is rarely used in trade. Typically, red zircons are very dark; often lighter specimens have a weakly saturated color. Naturally bright samples are also found, but more often heat treatment is used to lighten the color of dark samples.

We highlight reddish zircons of the following shades:

  • red (Red);
  • orange-red (Orangish Red);
  • pinkish red.

According to intensity, they are divided into medium (Medium), strong (Strong), deep (Deep) and dark (Dark). We recommend this stone to collectors and experienced gem lovers. The hardness of zircon is low – 6 on the Mohs scale, and it is quite fragile. You need to handle it carefully so as not to scratch it. It is very rare when cut zircons of reddish tones exceed 10 carats in weight.

7. Fire opal

Fire opals are a variety of natural opal in warm tones of Orange, Orange, and Red. Fire opals are distinguished with and without play of colored flashes. From a gemological point of view, the most expensive color of fire opal will be a rich orange-red with bright opalescence in the form of large flashes of green, blue and red.

In general, based on color intensity, such natural opals can be divided into groups: strong (Strong), intense (Intense) and saturated (Vivid). The redder the color of the opal, the more expensive it is. It should also be taken into account that with different types of lighting, the play of colored flashes in the stone can manifest itself to varying degrees. It will be best visible with bright point sources of light, less visible with diffused white light in partial shade, for example, near a window. Opal hardness is 5-6,5. They can be refined by painting or impregnation with polymers. For our clients, we try to select the brightest and most unrefined fire opals at a reasonable price.

8. Coral

Red corals are organic gemstones. They are used in jewelry in the form of elegant “twigs”, cabochons and carved items. Corals are characterized by a special structure by which they can be distinguished from imitations made of plastic or pressed materials. The following groups are distinguished by color and shade for corals:

  • pinkish red (Pinkish Red);
  • orange-red (Orangish Red);
  • red (Red).

Based on intensity, these groups are divided into medium (Medium), intense (Intense) and saturated (Vivid). The most expensive color is Vivid Red. Be careful, corals are often painted bright red. Their cost is significantly less than that of real specimens of natural color.
