Description

Several spheres of marcasite attractively set on quartz. Marcasite is very glossy and colorfull, shows a wide range of colors! Quartz crystals are all sharp terminated, lustrous and of good clarity. Really great contrast, very eyecatching and not very common material. The specimen is in a fine condition damage-wise. Marcasite is undamaged, only minor cleavage on not so prominent quartz crystals.
