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.

It is common to call imitations fake. Some may confuse lab-grown diamonds with other imitations such as cubic zirconia.

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.
