The ratio of the weight of a gemstone of the same volume to the weight of water is called the specific gravity. Divide the weight of the gemstone in the air by the difference between the weight of the gemstone in the air and the weight of the gemstone in the water, and the value obtained is the specific gravity. Taking diamond as an example, the specific gravity of diamond is 3.52, which means that the weight of diamond is 3.52 times of the same volume of water.

Hardness

The degree to which gems can withstand scratching is based on the Mohs hardness scale. Ten natural minerals represent the hardness standard of 1 ile 10. The lower the number, the lower the hardness, the more likely it is to be damaged by scratching. . The one representing 1 is talc, and the diamond with the highest hardness represents 10, which means that diamond is the hardest among all minerals.

Fakat, the hardness levels of these ten minerals are different from each other, but the hardness of the gemstone is selected as a reference indicator. Örneğin, the hardness of diamond is 10, hangisi 140 times that of corundum with hardness 9, and corundum is different from The topaz with a hardness of 8 is only 7 times different.

The only way to measure the hardness is to rub the gems against each other, depending on the degree of wear, but we do not recommend this destructive method for gem identification, so the hardness is mostly whether the gem surface gloss is good or not. index of.

The Mohs hardness is determined by the German mineralogist Mohs, and the hardness is ranked from low to high.

Dispersion

Dispersion is the time when white light enters the gem. The gem divides the light into seven colors of red, turuncu, sarı, yeşil, mavi, indigo, and purple. Simply put, it is the so-called prism phenomenon. This is because the wavelengths of the various colors contained in the white light are different. , The speed of travel in the gem is different, and it emits colorful light. The color of the gem with high dispersion rate is more obvious. This feature is what we call the “flame” of the gem. The dispersion rate of diamond is as high as 0.044, so it can emit Brilliant light like fire.
