    • 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...

    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.

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 · 「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 鑽石國際證書不只GIA，值得信賴的國際證書. 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。
