This natural Herkimer diamond crystal displays the sharp double terminated form collectors look for, combined with a distinctive dark internal window that gives the crystal remarkable depth. Light passes cleanly through much of the specimen, creating strong contrast between the transparent outer faces and the geometric structures suspended within.

Well defined faces, bright natural lustre and unusual internal features make this an appealing collector thumbnail. Under direct light the crystal reveals additional reflections, tiny inclusions and internal textures that are difficult to fully appreciate in photographs, giving the specimen a different character as it is rotated in the hand. Despite its modest size, it has the strong visual presence that has made Herkimer diamonds some of the most recognisable quartz crystals in the world.
