Pruskite is a trade name referring to artificial crystals of yellow potassium hexacyanoferrate(II) and red potassium ferricyanide, K3[Fe(CN)6], containing trivalent iron. Pruskite features a prominent red crystal atop a yellow base, radiating vibrant beauty and energizing any space. Pruskite crystals are exclusively lab-grown, rendering them rare and scarcely available in the market.
