1 Introduction Editor
Beryllite belongs to silicate crystals in mineralogy, which can show different colors, mainly depending on the genesis and formation conditions of the ore.
aquamarine
The following are common:
(1) The color of beryl containing chromium ranges from light to dark green, blue-green and yellow-green, and it is a very precious emerald.
(2) Iron: azure or aquamarine.
(3) Containing cesium, lithium and Morganite: the color is rose red, which is called cesium beryl.
(4) beryl containing iron, golden yellow and light lemon yellow is called golden beryl.
(5) The beryl containing titanium and iron is dark brown, which is called dark brown beryl.
(6) Colorless and transparent beryl is called Goshenite.
Beryl is a silicate containing beryllium and aluminum. The color of aquamarine is beryl from sky blue to sea blue or blue-green. Its color formation is mainly due to trace ferrous ions (Fe2+), and bright and flawless bright blue to light blue is the best.
Aquamarine is mainly produced in the pegmatite deposit-sugar albite pegmatite, and the most famous aquamarine producing area in the world is in minas gerais, Brazil. Followed by Russian, China and other regions. The common crystal morphology is hexagonal columnar, followed by hexagonal bipyramid, and the aggregates are mostly columnar. Transparent to translucent. The refractive index is 1.567- 1.590, and the birefringence is 0.005-0.007. Polychromaticity is obvious, from blue to blue-green. X-ray irradiation does not emit light. Good toughness.

Gems similar to aquamarine in the market mainly include topaz, zircon, crystal, glass and synthetic spinel.
Compared with blue topaz, although both topaz and topaz have fire color and beautiful blue color, topaz and its fire color have some black inside, which is not as pure as aquamarine and the crystal is not as transparent as aquamarine. So it's easy to distinguish between the two. People can also distinguish aquamarine from topaz by weighing. A major feature of topaz is its high density, which makes it feel heavier in your hand. If the two bracelets are aquamarine and topaz, the feeling of weight difference is obvious. At the same time, consumers
You can also judge whether a gem is aquamarine or topaz by its price. If sapphire blue is dark and inexpensive, it can't be aquamarine. [ 1]
Compared with zircon, zircon has a large proportion, strong dispersion, radiant appearance and obvious ghost.
Compared with glass and synthetic spinel, aquamarine often has slight dichroism, and gas-liquid inclusions are often seen in aquamarine.
3 Evaluation and purchase editing
These factors are color, transparency and weight. Dark color, flawless and heavy are the best products. Aquamarine is characterized by sky blue, sea blue, glassy luster, few inclusions, cleanliness, transparency, weak dichroism and hexagonal columnar crystal morphology. Aquamarine is fragile, afraid of high temperature, high temperature and explosion, and will fade when baked in fire.
4 market editor
Things are scarce, and aquamarine is also very valuable for collection from the perspective of long-term investment. As early as the beginning of the 20th century, the largest aquamarine crystal ever discovered in Brazil was 19 inch long, 16 inch wide, weighing 243 pounds, blue inside and green outside, clear and transparent. After the news spread, people from all over the world flocked to buy it, and finally it was bought by a German businessman at a sky-high price of 654.38+ one million marks. Think about what astronomical figures should be at the beginning of the 20th century. The high value of the best aquamarine can be seen. In China, the collection value of aquamarine should not be underestimated. For example, on July 9, 2009, a famous jewelry store in Guangzhou publicly auctioned an aquamarine of about 1 14.5 carats, and the starting price was as high as 500,000 yuan. However, aquamarine with real collection value is generally large, and only large enough can show the color of sea sapphire, which has high appreciation potential.
5 birthstone editor
Legend has it that aquamarine is produced at the bottom of the sea, but seawater is the essence. Therefore, navigators used it to pray for Poseidon's navigation safety and called it "the stone of luck". It is also considered as "the birthstone of March", symbolizing "calmness and courage" and "happiness and longevity".
The ancients found that aquamarine was as blue as seawater, so they gave it the attribute of water, thinking that this beautiful gem must come from the bottom of the sea and is the essence of seawater. Since then, aquamarine and "water" have forged an indissoluble bond. Therefore, for people born in March, jewelry made of aquamarine can not only bring extraordinary external beauty, but also bring shelter and happiness.

Westerners generally believe that wearing aquamarine can make people have foresight.
Because of the close relationship between aquamarine and water, it has long been regarded as an amulet, especially for people who live in the sea all the year round, and it is believed that aquamarine can capture the soul of the ocean. For centuries, sailors drifting on the waves used to use it to pray for navigation safety, so aquamarine is also called "mascot stone". In the movie Pirates of the Caribbean, if you watch it carefully, you will find that sailors who wear many fancy things mostly wear a blue gem around their necks, that is aquamarine.
Besides keeping peace, aquamarine is also called "the stone of love". In ancient Greek mythology, there was a Shen Feng named Roland, who was handsome and humble. Later he fell in love with a mortal woman, which was forbidden by the gods at that time. For loyalty,

His own love, he did not hesitate to pay his life. Before she died, Roland begged Venus, the goddess of love, to seal her soul in aquamarine as the birthstone of people born in March, and wished people to find their love. Therefore, people in Mediterranean countries like to wear aquamarine, so as to have sweet love and maintain a happy marriage.
In medieval Europe, craftsmen sliced aquamarine according to their needs and fixed it in the observation holes of some specific tools, so that nobles could see further. This is probably the origin of the telescope. Crystal clear aquamarine is often polished into a mirror, and some wizards insist that such a mirror can be used for divination.
With the development of science, people no longer believe that birthstones have the magic power to ward off evil spirits and bring good luck. However, as a cultural precipitation and beautiful expectation, the custom of wearing birthstones will continue to spread.
