Diamonds are still among the most sought after gems worldwide as they represent love, luxury, and eternal value. But, the advent of technology has made it a new problem for buyers who want to know whether the diamonds they buy are natural or artificial (lab, grown).

At first glance, the two seem pretty much the same. They both sparkle in the same way, have the same hardness, and even pass basic diamond tests. This confuses the buyers so much that they can't really tell what it is they are buying.
