Rock crystal is the colorless and transparent variety of quartz and is one of the best-known minerals. It typically forms well-developed prismatic crystals with clearly defined terminal faces, occurring as individual crystals, groups or specimens on matrix.
In this category, you will find rock crystal specimens from a range of localities and geological settings. The selection includes clear individual crystals, crystal groups, matrix specimens and pieces associated with other minerals.
Each specimen is documented with the most precise locality information possible, together with dimensions, weight and original photographs. Depending on the specimen, particular attention is given to transparency, crystal form, surface features, matrix, inclusions or distinctive growth forms.
Rock crystal is of particular interest both mineralogically and to collectors because crystal habit and quality can vary considerably depending on locality and formation conditions. The specimens offered here illustrate a range of forms from classic as well as less commonly represented localities around the world.
