2019年10月26日 · 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。 如果珍珠層單層像這樣整齊緊密的結合在一起，那麼整個珍珠表面就會呈現完美光滑的狀態。 如果像這樣，那麼整個珍珠表面就會出現褶皺、波紋等不平滑的視覺觀感。 珍珠層的鑑定就是用這樣一台儀器進行。 將珍珠放在白色測試台中央，很快顯示屏上就會顯示出珠層厚度了，非常方便快捷。 圖為我在日本真珠綜合研究所學習時拍攝的照片。 測量珍珠層厚度的儀器. 許多消費者特別注重珠層厚度，然後大家應該記住的是，只要是天女，厚度都已經達到了日本珍珠行業的標準，即都為0.4mm以上。 珍珠層的厚度與價格也沒有必然的聯繫。 決定akoya珍珠價格的依然是表面的品質，而非單一的珠層厚度。
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...

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...
