John Cordova (Vice President of Human Resources, Robbins Bros.) gives expert video advice on: Does it make any difference if I examine a diamond mounted or unmounted?; Should I ask the salesperson to clean the diamond before I view it?; When I examine a diamond should I use my hands or tweezers? and more...

When viewing diamonds, the diamonds should already be clean, and any great professional jewelry salesperson will always show you the diamond after having cleaned it.
