The world is big, there are no strange things. It is common to use famous gemstones such as rubies, sapphires, emeralds, diamonds, etc. Looking at the minerals, what are some beautiful but precious stones? If you have never read this article, you may not hear them in this life.
NO.1 strawberry beryl
In 2002, mineralogists discovered a new gemstone mineral deposit in Madagascar and Afghanistan. This gem mineral has a unique crystal form, mainly hexagonal plate column or stud, transparent to translucent, strawberry red is manganese-colored, hardness is 8.5 (close to ruby), the cause is similar to pink beryl, but different from red green pillar.
NO.2 scheelite
An ore with a granular shape, whiteish yellow, fatty luster, and fluorescent. It has a high birefringence and dispersion, so it looks like high gloss and visible "fire", much like a diamond.
NO.3 calcite
A widely distributed calcium carbonate mineral. Tap it, you can get a lot of square pieces, so the name is calcite, nicknamed "Fang Jie", can be described as "light body soft and easy to push down." The color like the picture is because it contains iron and manganese, it is generally white or colorless.
PS: "Fang Jie" is a famous "Aroma Master", which can improve the smell in the environment, and can be placed in the car, kitchen, toilet, cabinets and other odors, and can be deodorized.
NO.4 axe
It belongs to the triclinic system. The common colors are brown, purple, purple, brown, and blue. It is glassy, ​​transparent-translucent, and can be honed into a beautiful faceted gemstone, but it is easy to break (hardness 6~7). If you wear it with great care, it is generally used for collection.
PS: Very strong trichromism. For example, Nevada in the United States has reddish brown, yellowish brown, yellowish green or colorless. Sri Lanka produces reddish brown, deep purple, colorless or grayish yellow. Premium axe is produced in the French Alps and Tasmania in Australia.
NO.5 calcium nepheline
A carbonate-aluminum salt mineral containing sodium and calcium, very rare. It is a variety of colors, with some glass luster, transparent or translucent columnar, can be honed into faceted gemstones, but the hardness is not high.
NO.6 SiStanite
If the hardness of this product is high enough, it can be used as a black diamond, because it has the same diamond color as the diamond, but its hardness is only 6~6.5, and it is also low density. However, if you are pondered into a five-pointed star, you still have a "flavor".
NO.7 red zinc mine
A mineral that is difficult to find, with diamond luster, but too brittle, hardness is only 4~5, the color is orange yellow, dark red or maroon. It is said that there are only two mineral red zinc mines in the world (Lonkelin and Germany) In New Jersey, USA, in fact, I would say that it looks quite like rosin.
No.8 Cobalt
Cobalt, which has the reputation of “stone flowerâ€, is mostly earthy, and crystals are rarely seen (crystals have a glass luster, which is transparent to translucent). Its beautiful rose color is caused by the divalent cobalt ions contained in it, and when heated, it turns blue.
NO.9 borosilicate
Very rare, a fluoride-polymerized mineral of aluminum and boron, colorless, white, light yellow and light blue, glassy, ​​very transparent, distributed in Tajikistan, Namibia and the German Mount Eifel.

NO.10 Libya glass meteorite
This thing can only be in the sky! It is the world's purest natural glass, which begins to melt when heated to 1700 ° C and consists of nearly 98% pure silicon. The cause may be that the big comet collided to cause the ground and comet's fragments to melt rapidly and crystallize by instant cooling.
PS: The tomb of King Tutankhamen has countless treasures. One of the beetles' golden gems has attracted the attention of researchers. Later it was found to be made of Libyan glass meteorites.
