Description

Well-formed crystal of haüyne of superb blue colour, on matrix. No damages. Acquired in 2008, according to the associated information it was analysed by Raman and EDX by Dr Van Goethem, and he stays in an internal report:

“The emission spectrum, after correction for the blue background and it spinel signal, has maximums at 622 and 643 nm with approximately 18% amplitude. This also indicates a nosean but the maximum may have shifted due to underlying other emissions (e.g. Mn2+). EDX also does not provide a water analysis, but the sulphur concentration is high enough to go towards two atomic units. Haüyne is therefore also the most logical choice”.
