Unit 3 - Distinguishing Diamonds from Simulants and Synthetics
Although diamonds are unique in some of their optical and physical properties, some gemstones found in nature can simulate the appearance of diamonds. Many times, consumers can’t tell the difference between diamonds and these simulants. Some manufactured materials like cubic zirconia and even glass can imitate diamonds. People have also created synthetic diamonds, which are now attracting widespread attention as less expensive alternatives to mined diamonds. It’s critical to be able to distinguish natural diamonds from simulants and synthetics. (Hint: The Practical Exam focuses on your ability to distinguish diamonds from simulants and synthetics.)Prerequisites: The first three articles cover major diamond simulants, synthetic diamonds, and high pressure/high temperature (HPHT) treatments.
