2024年5月27日 · 「值得信賴」的鑑定機構. 說出幾個數字或是給予等級並不困難，真正的困難來自「公正性」，鑽石鑑定機構面對龐大的利益，要能持續做出公正客觀的裁決十分困難。 過去也有不肖業者自己化身鑑定師，或是自印證書，因此，建議尋求安心、知名的國際鑑定機構及品牌，消費者只要確認值得信任的國際證書內容即可，挑選鑽石更輕鬆。 延伸閱讀. 不只品牌保證書，建議挑選GIA、IGI等國際知名第三方鑑定單位. 挑選鑽石，不只GIA證書， 美國珠寶學院（Gemological lnstitute of America，簡稱GIA）雖然也是值得信任的國際鑑定單位，且知名度極高，不過在車工等級（Cut）最多只會評到Excellent。

- How Are Lab-Created Diamonds Made?
- Lab Grown Diamond Benefits
- What Colors Are available?
Each laboratory-created diamond is grown by placing a diamond ‘seed’ into a chamber of heat and pressure. This chamber mimics the natural growing process. Crystallization occurs allowing the lab-grown diamond to mature within six to ten weeks. It is then cut, polished and graded by the same world-renowned labs that certify earth-mined diamonds. The...

UNBEATABLE VALUE
Lab-created diamonds cost up-to 40% less than their mined diamond equivalents. Buyers beware: keep an eye out for "grown diamonds" sold for a few hundred dollars per carat. If the deal seems too good to be true, it probably is. Only diamond simulantsfall in this price range.
WHITE LAB-CREATED DIAMONDS
A pure carbon diamond with no impurities will grade as a colorless diamond. However, the majority of both mined and lab-created diamonds contain impurities, most of which are nitrogen. The nitrogen atoms within the diamond lattice create the yellow tint. In cases of fancy colored diamonds, a pure yellow color is created. Nearly all diamonds, both mined and lab-created, start out as yellow diamonds. Over the span of millions of years and exposure to pressure and heat, mined diamonds split the...

2024年5月27日 · 我想要一顆璀璨的鑽石. 車工指的是鑽石的切磨，好的車工精準計算角度、細微的尺度，讓光線的折射反射更加強烈，鑽石也更加火光璀璨、明亮奪目。 從下面這張簡單的圖片可以看出常見的車工陷阱，第一顆鑽石是經典的狀況，底部加深可以偷偷增加鑽石克拉數，讓鑽石售價更高，但卻因底部過深，光線由側面漏出，無法聚集火光，使得鑽石光彩相形黯淡。 而第三顆鑽石則是為了讓相同克拉數之下「桌面」更大，乍看鑽石更大顆，但深度不足，光線無法達到良好的折射效果，也嚴重減損鑽石的火光與價值。 完美車工的火光更耀眼. 好的車工是什麼？ 關於鑽石車工常見的名詞有三種：完美車工鑽石、八心八箭鑽石、3EX鑽石. 完美車工鑽石是什麼？
