3 天前 · 「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...
UNMATCHED BEAUTY
Our collection of lab-created diamonds are available up to IF in clarity, D in color, Ideal in cut, and up to 10 carats in size. They come in a variety of shapesincluding round, rose, emerald, cushion, oval, oval rose, heart, princess, trillion, and radiant. Colors include white, yellow, blue, pink, and green.
UNRIVALED QUALITY
Unlike other retailers, every Rooselle Jewelry lab-created diamond is Type IIa, the purest form of diamond. They are harder and more brilliant than Type Ia diamonds. Only 2% of earth-mined diamonds are of this quality. Furthermore, each diamond is graded and certified by the same leading independent gemological labs that are used to grade earth-mined diamonds.
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.

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...
