Which stone is more expensive than a diamond?

Red gemstones are always the center of attention. Rubin is one of those lucky ones. In Ancient India, it was treated with special honor: it was called the stone of the Sun and the “leader of gems.” Alchemists claimed that this was a clot of dragon blood that endowed the owner with the power of power. Color played a significant role in this. For many peoples, red was considered a symbol of vital energy or love. And the awe of the ruby ​​has not subsided centuries later. This is the color of the strongest emotions: from love to rage, from passion to anger. And in the arms of a precious frame, it fills life with incredible colors.

Do you think that diamonds are the most expensive stones in the world? If we consider the cost per carat, then rubies have long held the championship! These are the types of jewelry that claim to have investment value.

Ruby cut has dozens of options: from the classic round with 57 edges to pear-shaped and octagon. Specimens with low transparency or asterism are turned into cabochons. Star rubies made smooth without edges to further reveal their beauty and unusual natural effect. Asterism is obtained due to the inclusion of very thin strips of rutile. In the light they form the rays of a star. But the red ruby ​​looks best in an oval cut, which emphasizes the richness of the color and does not obscure the natural brilliance.

Remember King Solomon’s ring with the inscription “All things pass”? It was the ring with a star ruby ​​that adorned the sage’s index finger.

How much is a ruby ​​worth?

Rubies with subtle inclusions cost between $500 and $8000 per carat, while stones with lots of air bubbles, haze and low shine will average under $300. Heated rubies are cheaper. But stones without any refining are rather an exception at the appropriate price. Therefore, gemologists call this processing method acceptable. Heat removes unwanted purple undertones, blemishes and silky effects. Inclusions are not a death sentence if they do not reduce transparency. This is often evidence of the ruby’s authenticity and natural origin. But the work of a cutter is also important!

Factors influencing cost:

• origin;
• color saturation;
• transparency, purity;
• the weight;
• lack of heat treatment;
• cut.

The process occurs in 4 stages:

1. Polishing roughness.
2. Hydrogen fluoride purification.
3. Heat treatment to remove dirt inside cracks.
4. Heating in an electric oven: oiling and coating with orange lead powder, which becomes transparent after cooling.

Rubies that are flawless in color without heat treatment, glass filling or oiling are rare and expensive specimens, reaching a price of 30 thousand dollars per carat.

Most people in the world are sure that the most expensive precious stones are diamonds. However, it is not! Some jewelry costs more than even the most luxurious diamond jewelry due to the presence of stones that cost much more per carat than a clear diamond of the same weight. We are talking about the most beautiful rare stones. The demand for them is high, but only a few can afford such a purchase.

Red Diamond, No. 1

Deposits: Australia

The purest red diamond without inclusions and impurities is rarely found in nature. Only a few jewelers were lucky enough to see this stone with their own eyes, much less work with it in their workshop.

The most famous red diamond is the Hancock diamond. It was found in Brazil in the 1950s and was named after its owner, Warren Hancock, a collector of gemological rarities of that time. This stone is worth a trillion dollars today. Other famous red diamonds weighing about 5 carats – the round “Young Red” and the triangular “Red Shield” – are periodically exhibited in museums.

Taaffeit, No. 2

Deposits: Sri Lanka and Southern Tanzania

Taaffeite is a mineral of incredible beauty, known only to a few connoisseurs of masterpieces of stone-cutting art. It was first discovered by the Irishman Richard Taaffe, who gave this pale pink stone his name. Later, purple, blue and greenish taaffeites were found, which were immediately recognized as rare varieties.

Today this stone is purchased at a price of about $35000 per carat. The largest taaffeite, weighing 1 carats, was auctioned in Hong Kong in 33.

Sapphire Parparadzha, No. 3

Deposits: Sri Lanka, Vietnam, Thailand, Tanzania and Madagascar

This exquisite sapphire has received several names from jewelers. Among them are “scarlet yakhont”, “evening stone” and “mineral of dawn”. The value of the mineral lies in its orangish-pink color, which is by no means inherent in sapphires.

The name means “lotus flower” in Sinhala. Hindus believe that if you wear a padparadscha sapphire, you can achieve a state of enlightenment. Crystals of 1-2 carats are more common than larger examples.

Serendibit, No. 4

Deposits: Sri Lanka

The rare mineral serendibite was first mined in 1902 in Sri Lanka. It got its curious name from the ancient Arabic language, which was once spoken by the Sri Lankans. “Serendib” means Ceylon.

This gemstone is known to be extremely difficult to mine. Its blue color is somewhat reminiscent of topaz, but the two stones have completely different spectroscopic characteristics.

Today, serendibite is synonymous with elegance and luxury, and is coveted by the richest people on the planet.

Alexandrite, No. 5

Deposits: India, Tanzania, Brazil

Alexandrite owes its name to Count Perovsky, who named this stone in honor of the then heir to the throne, Alexander II. The count presented it to the prince on his sixteenth birthday. Russian alexandrite is the most famous in the world, since a significant amount of this mineral was mined in Russia until the end of the 19th century. However, subsequently the sources of alexandrite deposits in the country dried up, and today the stone is mined in the mountains of India, Tanzania, Brazil and other countries.

Alexandrite is interesting because it can reflect three different colors: green, red and yellow, depending on the viewing angle. Its curious and cheaper variety is the cat’s eye. This version of the stone reflects light, producing an effect similar to a cat’s pupil.

Paraiba Tourmaline, No. 6

Deposits: Brazil

We are talking about one of the most important gemological discoveries of the 10th century. Today it is undoubtedly one of the most expensive stones in the world. This is due to its rarity. For every 000 diamonds obtained from nature, only one Paraiba tourmaline is mined.

This mineral was first discovered in the 1980s thanks to geologist Hector Dimas Barbosa. The scientist spent decades searching for gemological beauties in the state of Paraiba in Brazil. In the end, he was lucky and provided azure-colored tourmaline to the jewelry market.

The exclusive gems described above are not only exceptionally beautiful and incredibly expensive, but can also be considered as a successful investment that will certainly pay off.
