  1. 1. 首先檢查爪子. 污垢有時是唯一粘在石底,特別是如果它是一件老舊的珠寶或長期未清潔。 擦洗時要小心,直接握住來使用毛巾擦拭.切勿放在水槽或地板上擦拭。 如果珠寶首飾鬆動,請先將珠寶首飾固定,然後再自行清潔。 2. 為鑽石混合含氨的清潔液及溫水. 一般常見的含氨清潔劑(如 windex或藍威寶 )將一杯溫水和1/4杯氨倒入一個碗中。 不要將鑽石直接放入混合物中。 相反,拿一把軟牙刷,並將其浸入混合物中(如您經常清洗請跳過這步) 3. 將溫水和洗潔精混合浸泡. 請使用一杯水和幾滴洗潔精 (如紅威寶)。 把珠寶放入混合物中。 在除之前讓珠寶浸泡大約20分鐘。 4. 用軟毛刷擦洗. 用已經浸入混合水的牙刷輕輕擦洗鑽石。 隨著清潔珠寶的主要部分,一定要進入小區域和石底部。

    • 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.

    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...
