Sample source 1: Lake Amboseli | Source location 1: Nairobi, Kenya | Sample source 2: British Museum |
Source location 2: Great Russell Street, London, WC1B-3DG, UK | Sample identifier 2: BM1974,217 | Sample source 3: The Natural History Museum, National Museums of Scotland |
Source location 3: Cromwell Road, London, SW7 5BD, UK, Edinburgh, UK | Color: Colorless | Other: Spectrum matches those from specimens from other localities, also that of Adler & Kerr, but not that in Sadtler (80), spectrum is easily distinguishable from that of the lower hydrate, pirssonite |
