  • How are lab-grown diamonds made?
    Grown diamonds are made one of two ways - eithr through high-pressure high temperature (HPHT), or through chemical vapour deposition (CVD). The majority of CJL's dimonds are grown using CVD which has been the most successful in producing higher quality diamonds. HIGH PRESSURE HIGH TEMPURATURE (HPHT) HPHT recreates the natural growing environment found within the earth. This process is best suited for producing gem quality dimonds to be set in finished jewellery. CHEMICAL VAPOR DEPOSITION (CVD) Scientists start by cutting a small piece of carbon, known as seed. It is placed in a low-pressure microwave chemical vapor deposition (CVD) chamber. Within 6-12 weeks, a sizable rough dimond is formed. It is then cut, polished, and graded by the same world-renowned labs that certify earth-mined diamonds.
  • What are the quality grades of lab-grown diamonds?
    Our collection of lab grown diamonds are available up to IF in clarity, D in color, Ideal in cut, with large carat weights in all shapes, including round, rose, emerald, cushion, oval, oval rose, heart, princess, trillion, and radiant. Limited quantity fancy colors are available in yellow, blue, pink, and green and fancy shapes such as triangle and hexagon.
  • What is the resale value of lab-grown diamonds?
    There are many ways to tell the difference between a fake diamond and the real thing. Turns out, the definition of a real diamond is not linked to origin (earth vs lab), but rather by its characteristics. Lab created or man made diamonds have been created replicating the earth's natural process, and will pass a diamond tester because of their identical characteristics.
  • Do all lab-grown diamonds look alike?
    No. A lot of people think we can program the process to create a specific diamond grade and carat size that are the same each time, but we can’t. We are simply putting the right conditions together but then nature takes it from there. Just like with earth-mined diamonds, there will be variances in color, clarity and carat size.
  • Can you tell the difference between an earth-mined and man-made diamond?
    Lab grown diamonds are indistinguishable from earth mined diamonds, even under a microscope, according to the Gemological Institute of America.
  • Are lab-created diamonds graded and certified?
    All CJL lab created diamonds over 0.5ct are graded the same way earth mined diamonds are and come with a grading certificate.
  • Are lab-grown diamonds more environmentally friendly?
    Unlike earth mined diamonds, our lab grown diamonds are created without negatively harming native communities, society or the Earth. Lab grown diamonds are seven times less impactful to the environment than mined diamonds, use significantly less resources and emit a fraction of the air pollution."
  • Does a lab-created or man-made diamond mean it is fake?
    There are many ways to tell the difference between a fake diamond and the real thing. Turns out, the definition of a real diamond is not linked to origin (earth vs lab), but rather by its characteristics. Lab created or man made diamonds have been created replicating the earth's natural process, and will pass a diamond tester because of their identical characteristics.
