  1. 4C的存在. Roselle Jewelry®的RZ®人造鑽石肉眼是完全與天然鑽石100%無差別,以鑽石相等的4C (顏色,切割,對稱,拋光)製作生產。 與坊間的CZ(香港、澳門稱為蘇聯石。 中國大陸稱為高碳鑽,SONA鑽,鍍膜鑽)對比火彩更為突出及更與鑽石像真-一般較差的CZ會以十心十箭或十六心十六箭等切割作為招徠. 與莫桑石對比,RZ®人造鑽石以天然鑽石相等的4C製作生產。 與莫桑石的雙折射材質不一樣。 所以通透度比莫桑石更為高更與鑽石像真。 RZ®人造鑽石的OEM(ORIGINAL DESIGN MANUFACTURER) RZ®人造鑽石從2015年開始以最完美的RZ寶石並保證肉眼100%與鑽石相符的因素開始外銷歐美等國家。

  3. 2019年7月19日 · 18K金是一種常用於珠寶的合金,但9K金呢? 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!

    • 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...
