  1. 2019年10月26日 · 試想一下,一條粉嫩可人的調色天女和一條偏白或偏黃的無調色天女,您會選擇哪條呢?市場價格通常是粉嫩的調色天女更哦。調色工藝既不影響品質,也不影響壽命(影響壽命的最大因素是你如何保養,沒有之一)。

  2. 2019年10月26日 · 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。 例例,就如同層一層的磚塊疊加,磚塊集合列整齊緊密,那這面牆就平整筆直而結實,如果磚塊排列不整齊,那這面牆就會凹凸不平很不美観。 如果珍珠層單層像這樣整齊緊密的結合在一個,那麼整個珍珠表面就會呈現完美光滑的狀態。

    • 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...
