Item Description
Pseudomalachite is a relatively uncommon hydrated copper phosphate found in the oxidized of copper deposits. A crystal druse of lustrous, emerald green, pseudomalachite has formed on colorless, quartz crystals, to 2.5 cm in length. This is an oldtime specimen from the heart of Cornwall. Most unusual - I have not seen another. Valued at $500.
