水晶表面坑洼的地方,有的深,有的浅,这是水晶在成长过程中自然形成的,并非是人为造成的损伤。缺陷位置本来包有其他矿物晶体,由于包裹体和水晶结合部位的结合力不强,当表面抛光时,矿体脱落,留下空位。这种缺陷在绿幽灵、钛晶、金发晶上都比较常见。

对水晶进行评价主要依据其颜色、透明度、大小、净度、特殊图案及是否有光学效应等方面。以颜色纯正,浓度较高,内部无瑕为好。种类上紫晶最贵,其次为黄晶、烟晶、无色水晶和芙蓉石。有特殊光学效应的水晶的价格更高。

条痕颜色:无色。矿物粉末的颜色叫条痕。它可以消除假色,减弱他色,保留自色,是比矿物的颜色更为可靠的鉴定特征之一。

Crystals appear exclusive from a number of other rocks and minerals, but �?barring a handful of Exclusive conditions �?almost all minerals hide a crystalline composition beneath the floor.

②固体包裹体:指呈固态相存在包裹体,多因岩浆、热液、变质作用等形成的早期结晶物被水晶捕获而形成。

广义的包裹体是指宝石内部含有的与主晶宝石化学成分、物理性质等不同的物质。

地质学家目前为止对晶洞形成还没有广泛认同的理论,但相信晶洞可以在任何埋藏的空腔内形成。这些空腔可以是火成岩中的气泡、树根下的空穴,甚至动物挖的地洞。经过漫长时间,空腔的外壁变硬,溶解的矽酸盐或方解石沉积到内壁。再经过漫长的时间,缓慢渗入的矿物使得晶体在空腔内部结晶。

Crystallography will be the research of crystals, and it promotions with all the things from ideal geometric shapes to seemingly random conglomerations of particles and minerals.

⑨、喷砂:立体感弱,较平整,无凹凸感,机器雕刻文字、图形等后进行效果处理。成本低制作快。

矿物成分:针铁矿、赤铁矿、金红石、磁铁矿、电气石、石榴石、云母、绿泥石等形成了包裹体水晶,如发晶、钛晶、绿幽灵等,发晶中则含有肉眼可见的似头发状的针状矿物的包裹体形成。含锰和铁者称紫水晶;含铁�?;呈金黄色或柠檬�?)称黄水晶;含锰和钛呈玫瑰色者称蔷薇石英,即粉水晶;烟色者称烟水晶;褐色者称茶晶;黑色透明者称为墨晶。
