As with most things in nature, diamonds have imperfections. Small carbon deposits which can help to identify a stone are called “inclusions.” Sometimes these also include tiny fractures that can be seen under magnification. Diamond clarity ranks from IF (Internally Flawless) to I-3 Heavily Included. Most of the ‘savings’ from jewelers, which only advertise price buster offers comes from inferior clarity or color of a stone. A stone with little to no inclusions is truly a rare find, and as such carries a price that reflects its rarity.
