Feldspar is a family of aluminosilicate minerals containing calcium, sodium and potassium. It is the most common mineral in the earth's crust. It is mainly divided into three major categories in mineralogy, namely potassium feldspar, plagioclase, and long stone. According to the chemical composition of different potassium feldspar series, it is divided into feldspar, translucent feldspar, micro plagioclase and feldspar; plagioclase series are divided into albite, aragonite, medium feldspar, elongated Stone, pebbles and anorthite. But the main related to gemology is potassium feldspar and plagioclase. The gemstones of the Changshi people vary greatly, giving them a variety of shapes and a variety of fascinating gemstones. Here are some of the famous varieties.
The light is faint as the autumn moon, who believes in the cold color of the stone - moonstone
Moonstone, also known as "moonstone", "moonstone", is called Moonstone in English. As the most valuable variety of feldspar gemstones, the moonstone is silent and simple, and the transparent gemstones are sparkling with blue light, which is a fascinating white moonlight. The beauty of the warmth that it radiates is the charm, so it is named moonstone.
Moonstone is a kind of feldspar. It belongs to the gem minerals in which the feldspar and albite are layered and arranged. The color of the moonstone is colorless, white, dark brown, brown and so on. Since the two minerals of feldspar and albite in the moonstone are in parallel with each other, their slight difference in light refraction makes a blue floating light on the surface of the feldspar, sometimes gray, orange, etc. Floating light, which has the highest value in blue. The blue is called the blue moonstone, and so on, as well as the white moonstone and the orange moonstone. Sometimes, you can also see moonstone with cat's eye and starlight effect, which is also very beautiful.
The gift of the sun god - Sunstone
In fact, in addition to the moonstone, the Changshi family also has a well-known gemstone member, sunstone. Sunlight stone, also known as "solar stone" or "Venus feldspar", is named after the feldspar, which has many neatly arranged and brightly colored flaky mineral inclusions. When illuminated by light, it reflects the golden highlights, like the sun. The shining light, it is said that it is a gift from the sun god to humanity.
The composition of the sun stone is sodium aragonite. Because the crystal contains reddish-brown platy mineral inclusions such as hematite and goethite, the golden light shining on the light reflects the “sunlight effectâ€, so it is called For the sun stone, this beautiful effect is also known as the gold effect. Sunlight stone is generally translucent dark orange, gold, golden brown, and occasionally colorless and transparent. In general, the sun stone is bright and enthusiasm, translucent and the body is strong, and the clarity is high and the transparency is rare.
On the side, it looks like a blue, while it looks like it is white - Labradorite
Labradorite, the English name labradorite, is one of the plagioclase. Labradorite is generally gray, brown to black, and the elongated stone that can be used as a gemstone has red, blue, and green halos. Labradorite is also known as Spectral Stone, because it can be named after the colorful light of the sun.
Because the labradorite often has a polycrystalline twin crystal or a fine alternating layer of albite formed by solid solution separation and microporous pores with parallel crystal planes, the transparent or translucent variety can have special optical effects— - Fainting effect.
Amazon Stone - Tianhe Stone
Tianhe Stone, also known as "Amazon Stone", the English name is amazonite. Its mineral composition is micro-plagioclase, which is a species of potassium feldspar. It is green, blue-green and sky blue due to a small amount of strontium and barium. It is micro-transparent-translucent, with a large production area and large yield. Used in jewelry materials, it is also a popular gem material, in which the emerald green Tianhe stone can be used as a substitute for jade. Tianhe stone has green and white with plaid spots and glitters. This is due to its unique and unique twin structure. This is the fundamental difference from jade. Tianhe stone is generally used to make carvings, the color is pure, the texture is bright, and the transparency is also good, so it is also very popular.
