18.98-Carat Emerald Octagon in 18K Yellow Gold, with Diamond Accents

Commanding in presence and saturated with lively green, this 18.98-carat natural emerald—cut in a refined octagonal, brilliant-style profile—is presented in a minimalist 18K yellow gold mounting that frames the gem’s crystalline depth. Subtle diamond accents (~0.20 carat) lend a discreet scintillation without distracting from the emerald’s intense color. Accompanied by C. Dunaigre, the stone is reported natural, Brazil, with indications of minor clarity enhancement, a customary practice for fine emeralds. A jewel of timeless appeal and collector-level scale, suited equally to connoisseurship and elegant wear.
