  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。

    • 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...

    YELLOW LAB-CREATED DIAMONDS

    Roselle Jewelry’s yellow lab-created diamonds are optically, chemically and physically identical to yellow earth-mined diamonds, but are offered free of conflict and on average 10% of the cost. They are available in a color range from fancy yellow to fancy vivid yellow, in sizes up to 2.0 carats and a variety of shapes. Both mined and lab-created yellow diamonds get their color from nitrogen. While diamonds are made up of carbon, impurities within the stone exist. It is the introduction of th...

    BLUE LAB-CREATED DIAMONDS

    Blue lab-created diamonds are optically, chemically and physically identical to blue earth-mined diamonds and are offered free of conflict and about 10% of the cost. They are typically offered in sizes smaller than 1.50 carats and come in a color range of fancy light blue to fancy intense blue. Both mined and lab-created blue diamonds get their color from boron. While diamonds are made up of carbon, impurities within the stone exist. It is the introduction of these impurities, in this case bo...

  4. 2019年10月26日 · 日本真珠綜合研究所とGIAの珠寶思用鑑定師Yoko來為您ソフト「天女」の個別側面。 天女項鏈. 關於天女,您要承知. 天女,由日本真珠科學研究所命名,白色系akoya珍珠中的卓越品質を代表する。 下半球會出現3種干涉色、即ち“極光效王”。 具備“極光效王”のあこや珍珠及び直徑在6mm以上、即命名為“極光天女”、一般簡稱為“天女”。 關於珠層: 天女珠層の標準為0.4mm,0.4mm以下の不可評価為天女。 很多賣家宣稱,珍珠層越厚珍珠光澤越美,很多買家も深為然。 珠層並非越厚光澤好,珠層厚並光澤,瑕畝有直接聯繫。 決定珍珠光澤は珍珠質層結晶層間の配列加重が平坦密であるかどうかです。
