Demantoid garnet is the green variety of the mineral andradite and a member of the garnet family. Over the years, it has earned the title of green garnet.
What sets demantoid garnet gemstones apart from the pack is its incomparable brilliance and fire. Some gemstone lovers claim that a demantoid continues to glow even in the shade. Rarity and remarkable radiance contribute to the value of demantoid. It owns a record of high refraction (refractive index 1.880 to 1.889), yet it is still capable of extraordinary dispersion with the ability to split light and break it down into the full spectrum of the rainbow. This is one of its finest assets, as it performs better than diamond. Demantoid ranges in many shades of green. It is common to find somewhat yellow-green to brown-green with a golden glow. While it earns praises for its exceptional appearance, most of its samples come in small sizes. It is rare to find it an enormous deposit. The majority of pieces will not exceed one carat, and few will weigh more than two after cutting.
