Is diamond pricing based solely on the 4 C’s of color, clarity, cut and carat weight?


Jewelry Judge Ben Gordon - GIA 4CsWhile the concept of the 4 C’s for diamonds was provided by GIA in 1953, and is a great industry standard today, there are additional factors to consider when pricing a diamond or other gemstone.

For example, the enhancement or treatment of a diamond (and gemstones) must be included as a price factor because it can have a significant impact on the price. Diamond treatments such as fracture filling and high heat + high pressure treatment did not exist prior to the 1980’s, but are common today. As are synthetic lab-grown (man-made) diamonds and look-a-likes, both have much less value than natural earth mined diamonds.

Transparency is also another price factor. Transparency is describes how clear, hazy, cloudy or opaque a gemstone is. It’s a separate factor from clarity. Hardly ever mentioned by retail jewelers, transparency has always been a value factor for colored gemstones, and it can be just as important as color in today’s diamonds.  Non-transparent diamonds are becoming more common in today’s color diamond market.

4CsSalespeople like a quick easy way of presenting gemstone pricing to their customers, so they use the 4 C’s.
