A 9.4 x 7.3 x 1.6 cm matrix plate, the top very richly crystallized with deep blue terminated undamaged azurite crystals measuring to 1.2 cm in length. I think somewhat better in person than as shown in the photos; there is a lot of very good azurite present. Minor green crystallized malachite in association. Ex Lloyd Tate collection.
