Lab Grown Diamond FAQ
There is no difference in composition and structure between lab-grown diamonds and natural diamonds. The main difference is the origin: natural diamonds have undergone millions of years of formation deep in the earth, while lab-grown diamonds are synthesized in a laboratory in a short time. In addition, cultured diamonds are usually more affordable.
Most jewelers cannot tell the difference between lab created and natural diamonds without specialized tools. Gemologists use advanced equipment, like UV light and high-magnification microscopes, to detect growth characteristics unique to lab diamonds.
Lab grown diamonds are composed almost entirely of carbon, arranged in a crystalline structure identical to that of natural diamonds. This structure gives diamonds their signature hardness, brilliance, and light-reflecting properties.
No, lab grown diamonds are not fake. They are real diamonds with the same chemical, optical, and physical properties as natural diamonds, both sharing the same carbon-based structure.
Yes, lab grown diamonds are as hard as natural diamonds, with a rating of 10 on the Mohs hardness scale. This hardness makes both lab grown and natural diamonds highly resistant to scratching and ideal for long-lasting jewelry.
Lab diamonds match natural diamonds in brilliance, durability, and quality, making them an excellent choice for those looking for a genuine diamond at a more affordable price.
Of course, all of the lab-grown diamonds we sell are IGI certified and laser inscribed with an identification number and/or unique symbol on the girdle of the diamond. Laser inscriptions can give you peace of mind when buying diamonds, as they are an easy way to identify a diamond.
