For five centuries, Preciosa has been seamlessly blending ancient tradition with the most innovative new technologies to create crystals and fine jewelry stones of unparalleled quality. Founded in the Crystal Valley of Bohemia, the local sand we use is uniquely rich in silicon-oxide, making it ideal for glassmaking, and our synthetic gems are almost indistinguishable from their natural counterparts. We are extremely proud of our long heritage, and it continues to be our pleasure to share authentic Bohemian crystal and fine jewelry stones with the world.
