    • 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...

  5. 6 天前 · 2024年5月27日. 在 新文章 0 comments. 「我想要一顆1克拉G VS1的鑽戒,請問售價多少? 走進鑽戒品牌,不少人第一句話便是指定克拉數、顏色淨度,這也是挑選鑽戒的最大誤區,許多人回到家裡之後打開戒盒,發現鑽石火光不夠璀璨,或是偶然發現別人的1克拉G VS1居然比自己的還要閃爍。 鑽石有4C,偏偏漏掉最重要的指標. 車工Cut是鑽石4C中唯一人為控制的指標,如果說顏色淨度是鑽石的胎記,那車工就是鑽石的靈魂,優秀的車工能讓鑽石光線更好地折射反射,透出絕美的七彩火光。 相較之下,鑽石顏色等級、鑽石淨度等級的差異反而不大,如果親眼比較,會發現顏色D與顏色F看起來差異極小,因此通常會建議選擇顏色I以上、淨度SI1以上的鑽石,並親自體驗感受鑽石火光是否璀璨,不需過度執著於等級。
