This 4.57 carat square emerald-cut tourmaline is a product of the Malkhan pegmatite field in the Transbaikal region of Russia – one of the world's most celebrated sources of fine pink and raspberry-red tourmaline, prized since Soviet times for exactly this kind of saturated, glowing color. The hue is a rich, juicy peach-raspberry, warm and tender rather than cold or purple-leaning, with even distribution across the full step-cut pavilion. The cutting itself is close to flawless – this is classic Russian precision faceting, with crisp, symmetrical step facets and a perfectly aligned table that lets the stone's hall-of-mirrors effect read cleanly straight down into the pavilion. Clarity is loupe clean, an exceptional grade for tourmaline of this size and one that most material from this locality doesn't reach. In hand the stone is extremely lively, with bright, saturated flashes moving across the facets at every angle. The color is entirely natural, with no heat treatment applied, confirmed by the accompanying Marianovich Gems Certificate of Authenticity.
