Here we have a superb Danburite crystal from well known Mexican locality La Bufa Mine at Charcas of San Luis Potosí. This single has outstanding quality with great clarity and gemminess, superb luster and excellent termination. The striation here is superb and the overall aesthetic will blast you away. Only minor imperfection extremely hard to see. This is material we have purchased a decade or so ago in the collection of Dirk Rheinländer and stashed it away for years.
