Almost all diamonds contain extremely small inclusions. Most are not discernible to the naked eye and require magnification to become apparent. They are nature’s fingerprints and make every diamond quite unique. The fewer there are, the rarer and more valuable the stone.
Clarity is the term used to indicate the extent to which the diamond you purchase is free of these natural inclusions under ten times magnification.
It is the cut that enables a diamond to make the best use of light. When a diamond is cut to good proportions, light is reflected and refracted from one facet to another and then dispersed through the crown or top of the stone. If the cut of the diamond is too deep or too shallow, some light escapes through the pavilion or bottom before it can be reflected.
