    2024年5月27日 · 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？ 數學家Marcel Tolkowsky 在1919年研究出圓形鑽石的完美車工比例，在腰圍直徑、台寬比、全深等數值都在完美車工範圍內的話，鑽石可以綻放最大的耀眼光彩。

    • 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.

    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...
