Demantoid is a green garnet variety within the garnet group, distinguished by its vibrant, emerald-like hue and high refractive index that yields notable brilliance. Crystals often form as well-shaped, prismatic dodecahedra or rhombic dodecahedra with a glassy to adamantine lustre, and some specimens display a horsetail or needle-like inclusion texture that can accentuate their facets. The color ranges from yellow-green to deep forest green, and when cut, the stones exhibit strong fire and scintillation that attract collectors who value bright, clean color in a relatively small, dense mineral.
