2019年10月26日 · 日本真珠科學研究所所長小松博在2001年發現，在珍珠專用鑑定儀器的觀測下，可以看到在優質akoya珍珠下半球會出現3種干涉色，即“極光效應”。 具備了“極光效應”的akoya珍珠且直徑在6mm以上的，即命名為“極光天女”，一般簡稱為“天女”。 關於珠層： 天女珠層的標準為0.4mm，0.4mm以下的不可評定為天女。 很多賣家宣稱，珍珠層越厚珍珠光澤越美，很多買家也深以為然。 然而事實並非如此。 珠層並非越厚光澤越好，珠層厚度與光澤、瑕疵沒有直接聯繫。 決定珍珠光澤的是珍珠質單層結晶層之間的排列疊加是否平整緊密。 舉個例子，就如同一層層的磚塊疊加，磚塊排列整齊緊密，那這面牆就平整筆直而且結實，如果磚塊排列不整齊，那這面牆就會凹凸不平很不美觀。
1. 首先檢查爪子. 污垢有時是唯一粘在石底，特別是如果它是一件老舊的珠寶或長期未清潔。 擦洗時要小心，直接握住來使用毛巾擦拭.切勿放在水槽或地板上擦拭。 如果珠寶首飾鬆動，請先將珠寶首飾固定，然後再自行清潔。 2. 為鑽石混合含氨的清潔液及溫水. 一般常見的含氨清潔劑（如 windex或藍威寶 ）將一杯溫水和1/4杯氨倒入一個碗中。 不要將鑽石直接放入混合物中。 相反，拿一把軟牙刷，並將其浸入混合物中（如您經常清洗請跳過這步） 3. 將溫水和洗潔精混合浸泡. 請使用一杯水和幾滴洗潔精 (如紅威寶)。 把珠寶放入混合物中。 在去除之前讓珠寶浸泡大約20分鐘。 4. 用軟毛刷擦洗. 用已經浸入混合水的牙刷輕輕擦洗鑽石。 隨著清潔珠寶的主要部分，一定要進入小區域和石底部。

- 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...
