Vintage German Gemstone Sample Collector's Box

This item is a vintage German mineralogical specimen collection box, specifically titled '30 echte Edelsteine und Schmucksteine aus aller Welt' (30 Genuine Gemstones and Decorative Stones from Around the World). The box features a dark, textured leatherette or pebble-grained hard cover, common in the mid-20th century. A paper label is adhered to the front, displaying German text and a graphic illustration of quartz crystals. The manufacturer is likely a scientific or educational supplier, possibly related to the 'Kleine Edelsteinkunde' series. The condition is poor to fair, showing significant secondary intervention. The cover exhibits corner bumping and edge wear. Most notably, the original label has been heavily defaced with blue and green ink scribbles, and the phrase 'Jewelry Stones' has been handwritten in black ink within a hand-drawn circle. This suggests the item was used as a teaching tool or owned by a child. Despite the external damage, such items traditionally contain small, glued-in polished or raw mineral specimens behind the cover. Based on the typography and materials, it likely dates from the 1950s to 1970s. The craftsmanship of the original box indicates a standard mass-produced educational product for mineral enthusiasts.
