钻石的物理性质和化学性质有很多,而使其具宝石价值的性质主要是它的硬度、净度和晶形。一、钻石的硬度矿物的硬度是指能抵抗外来机械作用力(研磨、刻划或压入)的能力。金刚石是自然界目前所知最硬的物质,也是唯一硬度最大的物质。但是,钻石很脆,它经不起与硬物碰撞和摔打,绝对不允许锤击。在宝石商店如不慎将钻石掉地摔碎,将要受到巨大的经济损失。
The physical and chemical properties of diamonds are many, and the nature of its gemstone value is its hardness, clarity and crystal form. First, the hardness of diamond Mineral hardness refers to the ability to resist external mechanical force (grinding, scratching or pressing into). Diamond is the hardest material known in nature and the only material with the highest hardness. However, the diamond is very fragile, it can not withstand the collision with the hard objects and beat, absolutely not allowed to hammer. In the jeweler’s store, such as accidentally broken diamonds, will be subject to tremendous economic losses.
