KG68L9: Stunning group of extremely curved clusters of Pyromorphite crystals, that give a globular aspect to the specimen. These very aerial and esthetic globular aggregates are on a Limonite matrix. With an extraordinary color and luster. It has been reported that the globular orange crystals from Bunker Hill are arsenic-rich Pyromorphite specimens, so we analyzed some samples and the results are that they really are pure Pyromorphite, with no arsenic.
The specimen is from the James Catmur collection and we’ll send the label with the piece.
