Introduction of natural blue crystals and how to distinguish them

In recent years, Blue Kyanite has become a favorite due to its special color. Blue Kyanite is blue in color, due to spots on the top of the crystal, or uneven texture color, resulting in a darker color in the middle, sometimes even forming a distinct circle, commonly known as the "eye of Blue Kyanite". This is a natural mineral that is embedded in the stone. This particular dotted shape has led people to believe that they are not natural. Today, let's learn more about Blue Kyanite and how to tell if it's real or not!

Introduction of Blue Kyanite
Blue Kyanite is a natural refractory mineral with high refractoriness and high temperature volume expansion. blue kyanite is a trigonal crystal system, usually flattened columnar crystals, with parallel stripes on the crystal surface, light blue or blue kyanite color, bright gray and white. Hardness is 5.5 -7.0, specific gravity: 3.53 - 3.65. the main mineral composition is Blue Kyanite and a small amount of silica, the secondary mineral composition is quartz, secondary minerals are black mica, gold mica, chlorite. theoretical composition of Blue Kyanite is 62.93%, for 37.07%. Since Blue Kyanite mineral crystals often contain a small amount of secondary mineral components, the content is generally not up to the theoretical value. For Blue Kyanite mineral concentrate, the content is the sum of blue kyanite and impurity minerals.

Identification of Blue Kyanite

• There are ways to identify Blue Kyanite, look at the ratio, check the density, look at the dispersion, special optical effects, etc.

• Check density: The characteristics of the natural products in the composition density brighten up the bright stones with 10x microscopic examination is the most natural and reliable way to determine. The burden of natural stone can be liquid, solid, gas, liquid and crystal, the number of small follicles of natural stones, the spiral-like pattern is the burden of decaying corpses adulterated with liquid poigu

• Look at the dispersion: The benefit is that the lights are bright, the gem, the force of dispersion, the need to be able to identify the main clues. As long as the diamond, natural cubic oxide error, error stone, rutile, emerald garnet, cassiterite, etc. can be clearly seen with the naked eye dispersion

• Special optical effect: Some Blue Kyanites have a special optical effect that appears with any optical sight, so that the field of view of the stone can be reduced.

In a word, Blue Kyanite with a round dot formed in an inhomogeneous body state like the one above is equally natural, you can refer to the above identification method, but I still think that if you want to make an accurate judgment, then you still have to go to an authoritative identification agency for identification.
