Origin & story
Imperial topaz is the rarest and most valuable topaz, glowing in warm shades of golden orange and peach-pink. Its name recalls the Russian tsars who once reserved it for themselves.
Fine material is scarce and highly prized. SOMSTONE evaluates imperial topaz for the richness of its golden hue and the clarity of its large, brilliant crystals.
