Description

Rich cabinet consisting of several demantoid 'moors' proudly protruding from a wavy asbestos froth, while all being on a pale green-green serpentine matrix.

The main moor is in the range of 2.5 cm, which is sizeable for the area. Demantoids are overall gemmy, glass green in color and with great lustre. Locally there are some minor deep green garnets too, which I suspect being chromian garnets.

By far the largest demantoid specimens I have kept, especially in such quality. Very esthetic, solid and in great conditions. It comes straight out of my collection.

With a very reasonable - for such specimen - reserve price
