Can I tell the difference between a synthetic and natural diamond?

John Cordova (Vice President of Human Resources, Robbins Bros.) gives expert video advice on: What are 'synthetic diamonds'?; What's the difference between synthetic and natural diamonds?; Why would I want to purchase a synthetic diamond? and more...

It is very difficult for the layman with the untrained eye to tell the difference between a natural and a synthetic diamond. There are telltale characteristics in both. Natural diamonds actually exhibit, under close inspection, they exhibit characteristics from the regions in which they were mined, where synthetic diamonds exhibit characteristics of the lab in which they were mined. So an expert could tell the difference but the average individual really couldn't.
