Crystal Trade Names, Synonyms & Misnomers

Herkimer 'Diamond' - not actually a Diamond, but a misnomer for a variety of double terminated Quartz


Naming is deeply rooted in our relationship to the natural world. Intrinsically, as humans we feel compelled to ascribe names to the immense beauty of form and myriad complexity of nature that surrounds us. Names hold power and vibration, and open new portals of connection to the natural world. On naming, biologist Michael Ohl notes that 'we feel we are among the initiated, the entrusted, the knowing.'

In the world of crystals, learning the nomenclature of species and subspecies is a big job. Mineralogical names are considered the 'gold standard' (yes, pun intended!) when it comes to crystal identification, often relating to the name of the mineral's type-locality, the geologist credited with its discovery, or a Greek or Latin root describing the stone's classical properties. However, especially for those new to crystals, it can be particularly confusing to discover that all is not what it seems when it comes to names. Trade names, metaphysical names and pure misnomers abound, often with little or no reference to the crystal's actual composition. Many names were developed over the last century by the fine jewellery industry as a means of 'romancing the stone' to create more intrigue around a particular gem, and the same is true for many metaphysical and marketing names today. In some instances, misleading misnomers have also been created to obscure the true identity of a stone. Not all is intended as deception, however, and some trade names have emerged in an attempt to distinguish subtle differences in formation, colour, or inclusions - especially for such a varied mineral group as Quartz. This list of 400+ names is the product of more than 15 years of industry knowledge and experience by Solstice Stones' founder Michelle Cunningham, and will undoubtedly be expanded upon as other trade names emerge. It aims to shed light on the true mineral origins behind each fancy new moniker (as well as some historical ones, too!). We hope this list may serve as a navigational tool and empowering reference, as well as offering some deeper insight into stones that may already be in your collection.
