Green flower jasper is an orbicular, microcrystalline variety of jasper (silica) characterized by flower‑like or rosette patterns in shades of green, often contrasted with cream, brown, or red spotting. It forms when silica‑rich fluids percolate through volcanic or altered host rocks and precipitate fine‑grained chalcedony and jasper, with color and pattern produced by mineral impurities such as iron, chlorite, or other trace elements and by rhythmic deposition; notable sources include Indonesia (Borneo), Madagascar, and parts of Africa and the Americas. The material is typically opaque with a waxy to vitreous luster, a Mohs hardness around 6.5–7, and is commonly cut and polished for cabochons, beads, and ornamental objects.

In metaphysical and crystal‑healing traditions, green flower jasper is associated with nurturing, growth, and emotional healing, often linked to the heart chakra and used to promote calm, patience, and connection to nature. Practitioners also attribute grounding, protection, and gentle encouragement for personal development and creativity to the stone; these metaphysical properties are spiritual beliefs and are not supported by scientific evidence.
