What is a lab-grown diamond?
A lab-grown diamond is a diamond that was chemically "grown" in a laboratory setting. These gemstones differ from natural "Earth grown" which are grown deep within the Earth. The difference has been compared to ice made in a freezer vs ice made in nature.

Do diamond testers detect lab diamonds as "fake" ?
Laboratory-grown diamonds will test the same as natural diamonds when tested with a diamond tester. We suggest having any diamond, lab-grown or natural, graded by a reputable laboratory vs using a diamond tester. Lab-grown diamonds can be identified in a reputable laboratory by their growth pattern. They are also inscribed with LG or Lab Grown on the girdle

Sparkle is a subjective characteristic. That being said, a lab-grown diamond that is well-cut and high-quality would sparkle just as much as a well-cut high-quality natural diamond.
Why do people call them fake diamonds?
It is common to call imitations fake. Some may confuse lab-grown diamonds with other imitations such as cubic zirconia. Lab-grown diamonds are not imitations, they are diamonds grown in a laboratory versus mined from the ground. That being said, knowing what you are buying is very important. We recommend only purchasing lab-grown diamonds or natural diamonds from a credible source and certified by a reputable grading laboratory.

How is a lab-grown diamond grown from a seed?
A diamond seed is placed in a specifically designed press. The growth chamber is heated to 1300-1600 degrees Celsius with pressures above 870,000 pounds per square inch. The molten metal dissolves the high purity carbon source. Carbon atoms precipitate on a small diamond seed crystal, and a lab-grown diamond begins to grow. The lab-grown crystal is then cut and polished by a diamond cutter.
What is the difference between a lab-grown diamond and moissanite?

Do they show the same quality? Or can people tell it's not real?
