    • 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

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

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...
