4.00 Ct. Brownish Green Cabochon Chrysoberyl from Tanzania

This extraordinary 4.00 carat oval chrysoberyl, measuring 8.20 by 7.70 by 6.17 millimeters, arrives as a rare and refined treasure for the discerning collector. Translucent and presenting a brownish green hue with intense color saturation, this cabochon is an uncommon specimen both in size and in tone when compared to the more frequently seen smaller or golden cat's-eye chrysoberils. Cabochon cut to maximize optical phenomena, eye clean at standard viewing distance, and finished to an excellent polish, this stone bears no enhancements and comes directly from Tanzania, a source respected for producing fine chrysoberyl. Pieces of this weight and clarity in a brownish green palette are seldom available, placing this gem among a very small group of natural stones that marry substantial carat weight with such a distinctive, nuanced coloration. Owning this gem means possessing a piece that will not reappear often, and that rarity elevates it beyond mere jewelry into the realm of heirloom investment.

The defining cat's-eye effect, or chatoyancy, of this chrysoberyl is a luminous, razor-sharp band of light that sweeps across the domed surface like a glint of silk, shifting with movement and light. The band is centered and focused, a consequence of the cabochon profile and the stone s internal parallel inclusions, and it reads crisply against the stone s deep brownish green body color, creating dramatic contrast and visual depth. Depending on lighting and angle, the band may appear as a concentrated line of pale green or silvery white, flanked by richer olive to brown zones, giving the gem an animated, living quality. At The Natural Gemstone Company we present this chrysoberyl as a singular offering, a limited opportunity to own a chatoyant gem of notable size, exceptional polish, and natural origin. For those who seek exclusivity, a conversation piece, and a lasting symbol of refined taste, this Tanzanian cat s-eye chrysoberyl stands apart, ready to be set into a bespoke piece that honors its rarity and ensures it will be treasured for generations.
