A moving hydrocarbon inclusion on a Herkimer diamond is considered extremely rare; while hydrocarbon inclusions are relatively common in Herkimer diamonds, finding one that visibly moves within the crystal, indicating a fluid-filled cavity, is a very unique and sought-after feature by collectors.

Herkimer diamonds are significantly rarer than traditional diamonds, as they are a uniquely double-terminated variety of quartz found only in a few specific locations, most notably Herkimer County, New York. True diamonds are a mineral composed of carbon, while Herkimer diamonds are quartz, a much more common mineral. While there are billions of true diamonds, the specific geological conditions that create Herkimer diamonds make them a much more scarce and unique find.
