Bayldonite is a hydrous copper lead arsenate. Church (1865) named the mineral in honor of Dr. John Bayldon (1837?-1872), an English physician. Ghose & Wan (1979) solved the crystal structure and confirmed the formula of Guillemin (1956).

This specimen consists of iron-stained vuggy quartz. Bayldonite forms curved aggregates of deep green crystals. This specimen was part of the Charles Trantham (1936-2020) estate.
