This 0.835 ct Russian demantoid garnet from the Korkodino deposit in the Ural Mountains carries the deep, juicy green that made Russian demantoid famous in the jewelry of the Fabergé era. It is a rich bottle green, dense and velvety, with a saturation that feels almost liquid. Under good light that depth opens up and the stone comes alive, glowing from within and flashing bright green and spectral fire across its crown. At the center of the table a beautiful horsetail fans outward from a small dark nucleus, its fine fibers spreading evenly in every direction like the spokes of a wheel. It is a perfectly classic expression of the inclusion that identifies Russian demantoid and confirms its natural birth in the serpentinites of the Urals. The round brilliant is Russian cut, measuring 5.75 × 5.68 × 3.70 mm. Its proportions are tuned to hold the deep color while keeping the stone lively and responsive to light. In person it is a bright, living gem whose color shifts from deep forest green to vivid emerald sparks as it moves. It is natural and untreated, confirmed by the Marianovich Gems Certificate of Authenticity. Deep bottle-green color, a classic radiating horsetail and precise Russian faceting make this a beautiful Korkodino demantoid in the true Russian tradition, made for a vintage-inspired ring, a fine pendant or a collection of historic Russian gemstones.
