Many people who trade in diamonds do not realize that the manner in which you handle your diamonds and diamond jewelry can actually impact the jewelry business. But there is a very simple and basic reason why this is true.
Diamonds whether studded in jewelry or loose, have a propensity to attract oil and grease and every time the diamond is handled, it tends to pick up some grease. As we all know, grease attracts dist particles from the air and eventually there is a layer of grease and dust that covers the surface of the diamond. And we all know that when that takes place the light that reflects from the diamond is affected negatively.
The property of diamonds to attract grease has not always been seen as a negative property. In the earlier years, miners used the knowledge of this property of diamonds to sort diamonds from other minerals and gemstones in the same ore. This was done by covering a belt in grease and wax and then allowing the crushed ore to run over the belt. As the crushed ore passed over the greasy belt, the uncut diamond rough would stick to the belt as the other minerals remained unaffected.
