“I inherited my father's diamond ring and am having it re-sized (in this case made smaller). In the examination of the diamond by the jeweler it was noted that there was an inclusion centered in the diamond. This is what appears to be a cloud inclusion with a very distinctive cube shape. My question is, do inclusions ever increase the value of a diamond based upon their rarity? This is about a 1 carat diamond.”
Great question Keith!
The size, shape, number, type and placement of inclusions or clarity characteristics (some times called “flaws”) are unique to every diamond and are often referred to as the stones “fingerprint”. While most diamonds will have one or more different types of inclusions the possibilities for nature are endless.
The distinctive clarity characteristics of diamonds are always fascinating to me and there are always collectors and scientists interested in such things – so the potential for an extremely rare inclusion(s) to increase the value of the diamond exists – but that in of itself would be rare.
A couple of years ago Sotheby’s had a 3.05Ct. heart shaped fancy yellow diamond with an cross shaped inclusion at it’s center. Apparently this diamond generated quite a bit of interest, especially among Christian groups, and was expected to sell for more than it’s asking price. Although I never did find out what the diamond actually sold for – it is a great example of an inclusion that is both rare and unique enough to be the determining factor in the value of the diamond.
This video clip doesn’t directly relate – but its’ my favorite form the series.
