鑽石切割法的演�?切割指金剛石是如何從原先開採的石礦中切割成寶石。切割往往是最能影響鑽石的品量及價值的一個指標，但是它卻沒有單一的分級方法。
切割完的鑽石，往往只有原石的一半重量。為了在鑽石保留最多的重量，或者要避開原石上的雜質，有些鑽石切割時會犧牲完美的切割比例。

同級重量、顏色，而切割得宜的鑽石，顯得比切割差的鑽石更為燿燦。判斷切割是否優良，要看鑽石的各種比例，各面是否對稱，各種角度等等。有時鑽石的切割角度相差數度，便會造成截然不同的效果。
最後，因為鑽石的稀有與珍貴，自然也可作為繁榮、富貴的象徵。除此之外，亦可代表著貴重、珍稀的愛情承諾，並與其「永垂不朽」的特色相呼應，代表了堅定、心意永不改變的可貴�?鑽石基本特性與歷史介紹

但這些費用都會隨著鑽石價格波動、價格等級設定、選擇購買的平台比如線上品牌、當地銀樓、個人珠寶工作坊、鑽飾品牌、國際珠寶品牌而有價格差異。
鑽石是最堅硬天然物質，它的硬度達到摩氏硬度中最高的第十級，比起水晶和藍寶石等高出逾十倍、甚至百倍。此外，鑽石是一種兼備亮光、火光和閃光的礦物結晶體，所以被人們視作稀有、瑰麗和耐久的完美結合�?
鑽石的硬度比大多數天然物質都來得高，有著堅硬、強韌的特性。甚至有「只有鑽石可刮傷鑽石」一說
鑽石是「碳」元素形成的石頭。在高溫及高壓之下，原子形成結晶體結構，稱為鑽石立方晶系。
高÷寬（平均直徑）= 全深百分比以寬度為基準（圓形則以平均直徑數為基準）。
第一次選購鑽石總會感到迷惘，到底鑽石要怎樣挑？大眾選擇鑽石常以鑽石等級、鑽石淨度為指標，鑽石等級、鑽石淨度亦是鑒定一顆鑽石價格的因素之一，以下就讓我們告訴你如何平衡鑽石等級、鑽石淨度，人人都可變成鑽石小專家！
