Precious stones actually have a very high value due to their hardness and rarity and are much more expensive compared to semi-precious stones. In general, high-quality types of stones such as diamonds, green emeralds, rubies, sapphires or any rare mineral are known as gemstones in the jewelry industry.

A variety of red gemstones
The types of red precious stones include ruby and agate, which we have introduced below. Of course, pink and red diamonds can be classified as red gemstones because they are very rare and expensive.
Red sapphire
If there is impurity inside the ruby stone and tiny black grains are seen in it, this gem is genuine. A large ruby gem with high quality and no impurities is very rare and expensive. Therefore, if you see such a red stone in large dimensions, know that it is either an artificial ruby or an artificial garnet or spinel. To maintain ruby stone, you should know that it is very strong and hard and less stones can scratch it. So don't worry about getting damaged with other jewelry. But ruby can damage other stones and gold and create scratches on their surface. Ruby is the stone of July. Therefore, in addition to increasing the energy of those born in July, it also increases their courage. It is also very useful for treating heart diseases, regulating blood flow and strengthening the kidneys. Due to its structural and magnetic characteristics, ruby strengthens the blood flow and affects organs such as the heart and strengthens the glands. Continuous use of this stone increases very low blood pressure. It also removes numbness and laxity and circulates blood in the eye area.
Agate
Pink diamond
We said that the pink diamond is very rare, but the pink diamond is the rarest of all. Among all the diamonds in the world, only one in a million diamonds are pink. Like colorless diamonds, pink diamonds have the highest clarity and quality. It might be interesting to know, in Hong Kong in 2017, a 59.60 carat pink diamond was sold for an astronomical price of $71.2 million. Pink diamond, like colorless diamond, cleanses the organs and strengthens the excretory system, including the bladder and kidneys. This precious stone prevents the formation of kidney stones, bladder and gall bladder stones.
Red diamond
The most expensive type of diamond in the world is clear and colorless. But this gem is found in nature in different colors, which are not structurally different, but rare atomic processes cause their color to change. Among others, we should mention the red diamond, which is very rare and can only be found in South Africa and Western Australia. Red diamonds and pink diamonds are among the rarest diamonds on the planet. Red diamond, like other diamonds, strengthens the brain and cerebellum, muscle system, nerves and its branches. It also plays an effective role in removing poisoning, relieving gout and strengthening the eyes.
Green gemstones
Emerald
Emerald is weak against heat and may crack due to heat. The most important factor in buying and selling emeralds is its grade. The grade of emerald depends on its brightness and lightness and the transparency of the stone. To make sure the emerald is original or fake, hold it under the light. A real emerald will not reflect any kind of color flash. Natural emeralds reflect small flashes, which are called fire. But a fake emerald shines like a rainbow of light, and in this way you can recognize that it is not original.
The first emeralds were mined in Upper Egypt in 2000 BC. Emerald stones were mined during the reign of Alexander the Great and were favored and collected by Cleopatra. The Aztecs and the Incas also sought emeralds, and the Mongols of India respected and valued them so much that they engraved scriptures on the stones to use them to ward off evil. Ancient Egyptians also used emeralds to treat eyes. Also, they put this precious stone in the mouth of the dead to speak better in that world. Doctors also used emerald for antidote and treatment of epilepsy or stomach diseases. Even now, some doctors believe in the healing properties of emerald and prescribe emerald decoction to treat cancer or to treat epilepsy and also treat dysentery.
Supreme Yade
Jadeite is one of the most expensive gemstones in the world, each carat of which is sold at an incredible price of 3 million dollars. Jadeite is highly prized for its high quality clarity and deep green shades. The most precious gemstones are mined in Myanmar. Jadeite is saturated with sodium and aluminum. This stone has a hardness between 6.5 and 7. Its color variety is high and its green color is the most famous. Hong Kong is another commercial center of this celestial stone. Jadeite is much harder and denser than nephrite. Also, due to its rarity, it has a much higher price and value than nephrite.
In ancient times, the Chinese considered this stone sacred and therefore placed it between the lips, ear holes and nose of the dead to keep the devil away from the dead. It is said that jade is a stone of peace and friendship and has anti-stress and anti-anxiety properties. Jade is also effective in treating seizures, lung diseases and skin diseases.
A variety of blue -colored stones
Turquoise
Turquoise is a water-based gemstone that forms in rocks and mountains. Compared to diamond, original turquoise has tiny pores, which is due to the presence of water in this stone. In general, to use turquoise stone in designing and making jewelry, this stone must be polished and its color and shape improved. Neyshabour turquoise is the best and most famous model of this stone, but there are plenty of Egyptian and American turquoise in the market. The color of Neyshabur turquoise is softer than other turquoises. Neyshabur turquoise is usually never a uniform blue and mineral compounds have created different patterns on the stone. Turquoise and its derivatives have many medicinal properties and due to its magnetic properties, it has a positive effect on the heart, eyes and liver. Turquoise stone helps the function of the heart by regularizing the blood circulation, or the turquoise stone strengthens the eyes. The turquoise stone is mentioned as a protective stone. So that it is said that some pilots and flight attendants in Europe use turquoise for safety in travel. The reason why turquoise is considered a symbol of friendship is that for the formation of this stone, aluminum and copper must work together to make a new mineral called turquoise. Therefore, this relationship has been interpreted as friendship and turquoise has become a symbol of friendship.
