What's the difference between crystal and diamond?
Crystals and diamonds are very beautiful jewels. They are both natural gems. The mineral composition of the crystal is timely, the chemical composition is silicon dioxide, and the Mohs hardness is 7, showing glass luster. Jewelry is mainly bracelets and pendants, and young girls are often seen wearing various types of crystal bracelets in summer. Diamond is the king of precious stones, its chemical composition is carbon, and its hardness is the highest Mohs 10. It is known as the hardest and eternal jewelry and has become one of the essential jewelry for marriage.
1. Diamonds and crystals
main distinction
The biggest difference between diamond and crystal is the hardness. Among the natural products known in the world, diamond has the highest hardness, and its Mohs hardness reaches 10, while the Mohs hardness of crystal is only 7. It can be seen that the hardness of crystal is much lower than that of diamond. Therefore, when we distinguish between diamonds and crystals, we can judge them by their hardness: when carving, the crystal is scratched.

Other differences
Besides hardness, the composition, luster and refractive index of diamonds and crystals are also different. For example, the main component of crystal is SiO2, and the main component of diamond is C. As far as luster is concerned, the luster of crystal is glass luster, the fracture is oily luster, and the luster of diamond is diamond luster. In addition, the refractive index of crystal is about 1.54, while that of diamond is about 2.42. Moreover, the refraction of diamond is the same in all directions, while the refractive index of crystal is different in two directions.
transparent
Pure and clean, the gas field is compelling. Some people think that the natural ability of crystal can change the magnetic field around the human body, purify the environment, ward off evil spirits, make money and bring good luck. In fact, crystals are formed in volcanic rocks, metamorphic rocks and sedimentary rocks, including many crystal inclusions, such as cotton wool, stars and clouds, and some needle-like or fibrous mineral inclusions, such as hair crystals.
diamond
Diamonds, also known as diamonds, were formed by carbon atoms at high temperature and pressure more than 3 billion years ago. Diamond has the highest hardness, high refractive index and strong luster, and it is not easy to wear after processing, and it will always be dazzling. Of course, there are inclusions in diamonds, which can be divided into many kinds. GIA, a professional jewelry organization, distinguishes the clarity of diamonds by clarity, which directly affects the quality and price of diamonds.
The above is Bian Xiao's introduction to the difference between crystal and diamond. Their main differences are hardness, composition, luster, refractive index and so on. Therefore, when we usually buy diamonds and crystals, we can distinguish them according to these differences between crystals and diamonds in case we make mistakes when buying them.
