2019年6月27日 · RZ人造鑽石是經過香港商標註冊的一款高仿人造鑽石，採用與傳統鑽石相同的八心八箭以及D色FL淨度3EX的標準進行切割。 讓人造鑽石看起來保證100%肉眼無差別。 相比一般市場上的仿鑽更像真，沒有蘇聯石 (高碳鑽)的死白且膠的質感，也沒有莫桑石 (魔星石)的重影朦朧問題。 2.價格只需鑽石的1%： 相對天然的鑽石來說，RZ人造鑽石除了不能經過專業的鑽石儀器測試以外。 其他在肉眼層面都是相同的，對於一般外在要完全相似而不想花費太多或想要做日常替換或多點款式的顧客來說是非常便宜的方案！ 起碼…不會買到破產. 3.永不變色變矇： 如果您有經歷過選購仿鑽的經驗，必定試過剛剛買的時候覺得很閃很亮。 但過了大約幾個月之後，手上的仿鑽越來越發白，越來越朦朧，塑膠感越來越重。

- 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...

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...

2019年6月25日 · 因為Roselle Jewelry品牌之擁有公司是以鑽石切割及鑽石批發主要生意，有自家的切割廠以及自家的鑽石鑲嵌師父。 一般仿鑽非人造鑽石 (如蘇聯石 (又名高碳鑽、俄羅斯鑽))並不是真的鑽石切割。 一般沒有購買枕形切割經驗的顧客會覺得差別不大而購買劣質仿鑽。 假如你是一個擁有枕形鑽石的顧客，你是絕對不會選擇RZ人造鑽石以外的仿鑽。 並且這種材質做多面切割則是有幾個缺點。
