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.

4 天前 · 我想要一顆璀璨的鑽石. 車工指的是鑽石的切磨，好的車工精準計算角度、細微的尺度，讓光線的折射反射更加強烈，鑽石也更加火光璀璨、明亮奪目。 從下面這張簡單的圖片可以看出常見的車工陷阱，第一顆鑽石是經典的狀況，底部加深可以偷偷增加鑽石克拉數，讓鑽石售價更高，但卻因底部過深，光線由側面漏出，無法聚集火光，使得鑽石光彩相形黯淡。 而第三顆鑽石則是為了讓相同克拉數之下「桌面」更大，乍看鑽石更大顆，但深度不足，光線無法達到良好的折射效果，也嚴重減損鑽石的火光與價值。 完美車工的火光更耀眼. 好的車工是什麼？ 關於鑽石車工常見的名詞有三種：完美車工鑽石、八心八箭鑽石、3EX鑽石. 完美車工鑽石是什麼？

- 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

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

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.
