The Bitterfeld crystal-growing company in Germany has long since ceased operations. We were fortunate to acquire this lot from a European collector who preserved the material. We are especially thrilled to offer the lavender hue, as it stands apart from the colors produced by the modern Swiss company Djeva, which does not appear to have created anything similar. Only a very limited quantity of this vintage material was obtained, making it a truly unique find.
