6.64 Ct. Brown Cabochon Chrysoberyl from Ceylon (Sri Lanka)

This exceptional 6.64 carat round brown chrysoberyl cabochon hails from Ceylon Sri Lanka and arrives as a rare offering from The Natural Gemstone Company, a piece for the collector who appreciates understated power and natural beauty. The gem measures 10.03 by 10.15 by 6.71 mm, is cabochon cut to amplify its optical phenomena, and carries a clarity grade of very slightly included as evaluated at eye level. There has been no enhancement, the color intensity is vivid, and the polish is excellent, making each surface and curve glow under direct light. What truly sets this stone apart is its striking cat eye effect, a precise band of light known as chatoyancy that sweeps across the dome as the stone is moved. The chatoyant band is sharp and well centered, producing a lively, silky line that bisects the gem with remarkable clarity and draws attention with each turn. In direct sunlight or focused studio light that band narrows into a needle bright strip, while under softer lighting it broadens into a luminous ribbon that seems to float on the surface, giving the illusion of depth and motion within the chrysoberyl.

Beyond its visual majesty this chrysoberyl is built for everyday elegance, offering durability that suits daily wear with confidence. Chrysoberyl rates 8.5 on the Mohs scale, which gives it superior resistance to scratches compared with common gemstones, and its natural toughness reduces the likelihood of chipping during normal use. The cabochon shape further protects the stone, distributing impact over a rounded surface and minimizing exposed edges, which makes this piece especially well suited for rings pendants and statement pieces intended for regular wear. Because the gem is untreated and of dependable toughness this cabochon will retain its chatoyancy and polish through years of use with routine care, and it will develop a distinguished presence that improves with close acquaintance. Owning this 6.64 carat Ceylon chrysoberyl is an invitation to join an elite circle of collectors who value rarity, provenance and enduring quality, and The Natural Gemstone Company is pleased to offer this singular cat eye for immediate consideration.
