Description

This is a super fine specimen from the famous Dr. Hans-Jürgen Wilke collection. It features a single hexagonal crystal of medium blue-green aquamarine associated with also hexagonal blades of muscovite. The aqua is mostly transparent, very well developed and shows an indistinct but visible colour-zoning. The termination is perfect as well and the whole crystal is high lustrous and in very good shape. This is in any case an aesthetic and classic piece from the old times; probably the 1970ies; not comparable with the "modern stuff" and consequently difficult to obtain.
