Its minerals are widely distributed and are produced in all parts of the north and south of my country. (The above three types of gems, stones and crystals are inorganic gems)nbsp;nbsp;Coral - divided into red and white colors, it is a seabed coelenterate fossil, and the quality produced in Taiwan Province of my country is very good. nbsp;nbsp;Pearls - pearls (seawater pearls, freshwater pearls), cultured pearls (seawater cultured pearls, freshwater cultured pearls). (Coral and pearls are organic gems, also known as biological gems.) Gem minerals are the general name for natural minerals with gem value.

The main factors that determine the value of gemstones are bright color, flawless transparency, brilliant luster, or optical effects such as color change, discoloration, starlight cat's eye, etc.; rare output; hardness and durability, with a Moss hardness of above six, and high chemical stability. nbsp;nbsp;nbsp;Gem minerals are mostly natural elements, oxides or oxygen-containing salt minerals, of which silicate minerals account for nearly half. More than 3,000 minerals have been discovered in nature, but less than 10% have gem value. Among them, precious gem mineral species include diamond (diamond), emerald (beryl), ruby ??(corundum), sapphire (corundum), Cat's eye (chrysoberyl), alexandrite (emerald) and jade (jadeite), etc. nbsp;nbsp;nbsp;nbsp;nbsp;nbsp;Diamonds are treasures that are colorless, transparent and brilliant; while emeralds, rubies and sapphires are famous for their magnificent colors.

Many of them are synthetic minerals and various imitations that have the same chemical composition, crystal structure, and physical and chemical properties as natural gem minerals.

Question 7: Which color of sapphire is the most valuable? Sapphires are of course large particles, from Kashmir. Natural cornflower blue sapphires are the most valuable.

Question 8: The most valuable sapphire gemstone, what is the color of the most expensive sapphire? Among sapphires, there is a kind of blue like the German royal flower cornflower (Cornflower), which has breathtaking color charm. Elegant, bright and fascinating, this color of sapphire is called "Corn Flower" - it is the well-deserved king of the best sapphires!

1. Cornflower color

"Cornflower" sapphire has a pure, transparent and bright color. It has a hazy, slightly purple tint of deep blue, and gives people a unique velvety texture and appearance. This texture originates from Some small filamentous inclusions distributed inside the gemstone. Observing the gem with the naked eye, there is no variegation, and only a weak natural color band can be seen on the back. With excellent cutting technology, the whole gem gives people a dream-like beauty.

2. The output is rare

"Cornflower" sapphire is produced in the Kashmir area of ??the Zasgar Mountains in the Himalayas, the world's famous peak with an altitude of more than 5,000 meters, where it can be found all year round. The snow makes mining extremely difficult. Mining was completely stopped in the early 20th century, and the extremely rare production makes every existing gemstone precious.

3. The value of cornflowers

The top "cornflowers" are valuable if they have high clarity, deep color, and no color bands (that is, each stripe is darker than the overall color) or light texture), its value is immeasurable and it has become the most watched sapphire at auction today.

Question 9: Which gemstone is the most valuable in the world? ALEXANDRITE, also known as chrysoberyl, is one of the five most valuable gemstones and is a color-changing variety of chrysoberyl. Under daylight or daylight-type light, its color usually appears gray-green, light yellow-green to blue-green; but under incandescent light sources, it usually looks brown-red or purple-red. Commonly known as "emerald by day, ruby ??by night".

Compared with traditional rubies, emeralds and sapphires, alexandrite is a newcomer in the gem industry. It was first discovered in the 1830s in the Ural Mountains of Russia during the Tsarist era, near the gem center of Sfrovsk. A group of workers working at the TOKAWAJA emerald mine in the Ur Mountains discovered that some emerald-like gemstones had a strange discoloration phenomenon. They appeared green under sunlight during the day and red under candlelight at night, so they were presented To the Tsar ***, since it was discovered when Crown Prince Alexander (later became Tsar Alexander II) came of age, to express his congratulations. Named after this gemstone.

The reason why alexandrite changes color can be explained from the absorption spectrum of alexandrite. Some chrysoberyl have selective light absorption, absorbing orange-yellow-green light, but basically not absorbing red light and green light. In this way, the green wavelength of light in the sunlight is stronger during the day, and the gem will appear green. The red wavelength of light is stronger at night, and the gem will appear red under candlelight.

The main factors that affect the price of alexandrite are the color change effect, size, transparency and number of flaws of the alexandrite. Generally speaking, the more obvious the discoloration effect is, such as emerald green during the day and bright red at night, the higher the price. But under normal circumstances, there are very few gemstones with such an obvious discoloration effect. They usually appear dark green during the day and reddish brown at night, that is, they look like green tourmaline during the day and pomegranate red at night.

Alexandrite is a treasure among gemstones and has high collection value. It is very rare to have more than 5 carats.

Today, the production of alexandrite is extremely rare. The most important sources are Brazil and Sri Lanka, and others include Myanmar, Tanzania and Zimbabwe.
