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。
2022年9月27日 · 近年越來越多珠寶商改用實驗室培育鑽石，認為可減少使用與不道德生產方法有關的原材料；同時認為可降低生產成本，使更多消費者能夠購買到鑽石珠寶。 而根據安特衛普世界鑽石中心（Antwerp World Diamond Centre and Bain）的研究報告指出，實驗室培育鑽石市場目前正在迅速增長，尤其是年輕客戶特別熱衷於尋找可持續珠寶品牌。 兩者外觀上有何分別？ 兩者不同只可由鑒定機構專業技術設備偵測，但肉眼難以分辨。 與天然鑽石有何不同？ 兩者都是純碳打造，擁有一樣的光學特性，但培育鑽石可被無限制地創造，天然鑽石的形成則需要千年以上。 兩者價格有何分別？ 天然鑽石的價格由每顆鑽石獨特的特徵和稀少性所決定，但人造鑽石則可大量生產，故價格比相同尺寸與品質的天然鑽石低很多。
Roselle Jewelry® RZ®人造鑽石是獨家的配方合成寶石粉未混合一起, 再經過高壓壓縮後, 使用高反射防熱材質加熱至高溫鎔化合成的原料晶體, 等待冷卻後再經由利用高能超聲波進行化學蒸氣沉積處理處理以令其硬度接近天然鑽石。 經此方法礙結而成的晶體除了硬度更接近鑽石外,外表更有如鑽石一樣璀璨火彩, 更解決了一般方晶鋯石發白, 不夠透亮的問題。 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.

- 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...
2022年5月30日 · 您將面臨的最緊迫的問題之一是是購買天然來源的鑽石還是購買實驗室培育的鑽石。 不要驚慌，我們在這里為您分解，您和您的新娘肯定會理解。 那麼，有什麼大不了的呢？ 實驗室培育鑽石與天然鑽石有區別嗎？ 當然，有。 但你怎麼知道？ 數十年的研究和技術進步現在使這項艱鉅的任務變得更加容易，並且系統每天都在改進。 1. 天然地球開采的鑽石是如何形成的. 鑽石的存在時間幾乎與地球一樣長。 一顆天然來源的鑽石在地球表面深處形成了數十億年。 鑽石本身是由於極端壓力和高溫而形成的。 然後它通過火山噴發被帶到地表，並位於被稱為“金伯利岩管”的火山岩層中。 然後，鑽石耐心等待專業採礦工程師開採。 根據維基百科，採礦工程是一門將科學技術應用於從地球上提取礦物的工程學科。 2. 天然地球開采的鑽石由什麼材料製成：
