Kimzeyite Garnet: Gemstone Information
Found in carbonatite at Magnet Cove, Arkansas, USA (dark brown), in shoshonite basalt at Stromboli, Italy (brown), and in lamprophyre dykes, McKellar Harbour, Ontario, Canada (pale reddish orange). Crystals up to 5 mm are found at Magnet Cove.
Kimzeyite Not reported as gem material. It has zirconium as a major component; however, zirconium has been noted as a minor constituent of titanian andradites. Isomorphic replacement exists such that the kimzeyite molecule can occur in andradite and garnets in the schorlomite–kimzey series where its presence will affect the properties of these species.
