Physical properties

Formation & geological history
Formed in hydrothermal veins and pegmatites. The 'garden' or 'phantom' effect occurs when growth is interrupted and minerals like chlorite settle on the surface before quartz growth resumes, encapsulating the landscape-like inclusions.
Uses & applications
Predominantly used in jewelry (beads, cabochons, pendants) and as decorative lapidary specimens. Highly valued in metaphysical and crystal collecting communities.
Geological facts
Also known as Lodolite quartz. Each stone is unique because the internal 'landscapes' are formed by random mineral deposits during different geological phases of the quartz's growth.
Field identification & locations
Identify in the field by looking for clear quartz crystals that appear to have moss, forest, or underwater scenes trapped inside. Common locations include Minas Gerais, Brazil, and various regions in Madagascar.
