Natural Demantoid Garnet – 5.07ct – Round Cut – Vivid/Deep Green – ALGT Certified A rare find within an already rare gemstone category: an exceptional size demantoid garnet, distinguished by its size, excellent cut, vivid to deep green color, and unique natural inclusions. Demantoid garnet is one of the rarest and most prized members of the garnet family, admired for its exceptional brilliance and remarkable dispersion, often referred to as “fire.” Due to its very high refractive index, demantoid can display even more spectral fire than diamond, producing vivid flashes of colored light under illumination. Unlike many gemstones, where high clarity is generally the main preference, demantoids are appreciated for their characteristic natural inclusions, particularly the sought-after serpentine horsetail and columnar inclusions. Its vivid to deep green color is caused by chromium, the same coloring element responsible for the finest emeralds, giving demantoid its rich, lively, and highly desirable appearance. Combined with its outstanding optical performance and rarity, demantoid has long been considered one of the most collectible garnets in the world. The photos were taken in strong daylight, allowing you to appreciate the stone’s fire, life, and beautiful transformation from deep green to vivid green. This piece also displays excellent brilliance and transparency, further enhanced by its well-balanced round cut and distinctive natural inclusions. Specifications.
