- 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.

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...
