The original name of the jadeite is jadeite, which has a high hardness, so the toughness is also relatively large, composed of aluminate minerals. When the jade belt is maintained on the body, it will avoid some bumps. It is concluded that the hardness and toughness are high, and the embrittlement and fragility characteristics of the jadeite are avoided. Is this the case?
The so-called gemstone toughness refers to the resistance to hammering, stamping, cutting, and tearing. Compared with toughness, it is easily broken into brittleness by external force. To explain briefly, it is very difficult for the jade to tear and break the crack. This is the toughness at work, the toughness and hardness are not directly related, and the fall is easy to break and the brittleness is working.
Only toughness is related to the crystal structure and structure of minerals. Just like the microcrystalline aggregate black diamond, it is known that its toughness is the biggest, it is difficult to be easy to break, and the felt structure is the toughness of nephrite like the jade; the jadeite with the intertwined structure of the jadeite fiber is again The jade of granular structure or fibrous granular structure such as Dushan jade and quartzite jade has the worst toughness and is also brittle. This is the so-called gap.
Therefore, the emerald toughness is still good, this toughness is relative to other gemstones, and the toughness of the metal is not a grade at all. Resilience determines that jade has the ability to resist tearing and breaking, but this ability is limited. From the aspect of brittleness and jade texture, jade has high brittleness at the same time, which leads to jade breakage, breakage, etc. when it is beaten. .
The conclusion is that jadeite durability depends on hardness and toughness. High hardness and high toughness can make jade wear-resistant and not afraid of general scribing and friction, but it does not mean that it is not afraid of being beaten or dropped. Almost all natural gemstones are brittle gemstones, so they need to be carefully maintained to avoid falling or colliding.
