    • 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.

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...

  3. 2019年7月19日 · 這兩種金如何比較,它們之間有什麼區別? 9K金含有9份純金和15份其他金屬,如銀,錫,鎳,鋅,鈀等。 按百分比計算,9K金的純度為37.5% - 這是它所含純金的比例。 18K金的含量. 18K金每24合金含有18份純金。 因此,其金純度為75%。 由於其相對較高的純度和良好的耐用性,18K金是珠寶中最常用的合金之一。 9K和18K金有何不同? 正如我們之前看到的,9K和18K金的純度差別很大。 其他最重要的差異,源於純度的差異,是9K和18K的價格,耐用性和顏色,以及它們是否實際上被認為是黃金。 黃金狀況:9K並不總是被認為是黃金! 也許你應該注意的最重要的事實之一是,雖然18K金被認為是金,但9K金的情況並非總是如此,具體取決於它 所銷售的國家 。

  4. 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?
