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.
2022年5月30日 · 第一種方法基本上模擬瞭如何使用高壓和高溫在地殼深處製造鑽石。 這種方法稱為 HTHP。 第二種稱為化學氣相沉積或 CVD 的方法涉及“將富含碳的氣體（如甲烷）的分子分解成碳和氫原子，然後將它們沉積在金剛石晶種上，以產生方形的板狀金剛石晶體 ”根據 GIA 官方教育網站。 與在地表深處需要數十億年才能形成的天然鑽石相比，實驗室製造的鑽石可能需要一個月左右的時間就能製成。 僅此事實就吸引了買家（您），因為他們通常會發現自然過程更加獨特，因此願意在其上花更多的錢。
無論您選擇哪種金屬，都要採取以下措施保持您的珠寶拋光和無划痕： 將珠寶存放在獨立的珠寶盒或珠寶盒的隔間中以避免劃傷。 用溫和洗滌劑和溫水清洗珠寶，徹底沖洗並用軟布擦乾。 不要用成人牙刷擦洗貴金屬。為了清除裂縫中的堅硬污垢，您可以輕柔地使用柔軟刷毛的兒童牙刷。 去除手工 ...
- 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...
