The necklace is preserved in its original pre-war construction and represents an authentic object of its time without later rebuilding or alterations. Material and colour Originally the material was light in colour – milky. Over many decades the plastic naturally aged and oxidised, developing a warm orange-brown tone. This colour is not paint and not artificial dye. It is a natural patina formed over many decades. The colour distribution is irregular, with transitions from lighter orange areas to deeper brown tones, which is typical for naturally aged early plastics. A polishing test with Simichrome paste revealed the original milky base colour beneath the surface layer, confirming that the present tone is a result of natural ageing rather than applied colouring. Patina and age marks The beads show numerous surface scratches formed during decades of life and use. Inside these scratches the patina appears darker, as oxidation accumulated in the grooves over time. These darker lines create a strong visual contrast and add depth and character to the beads. Rather than reducing the value, these marks form an authentic antique surface that collectors often appreciate as evidence of genuine age. Bead size and construction The beads are large (around 30 mm and more), typical for statement necklaces of the early 20th century. The drill holes are unusually wide, an engineering solution often used at the time to reduce internal stress in early plastics and prevent cracking. Weight Total weight approximately 80 grams. The beads are not hollow, but the wide internal channel reduces overall weight while maintaining the impressive bead size. Assembly The necklace is strung on a double metal cable, a characteristic feature of quality pre-war construction. One strand of the cable shows a break under one bead, while the second strand remains intact and securely holds the necklace. Metal and clasp Metal elements appear to be brass or bronze alloy with natural age patina. The clasp is a large ribbed screw clasp with a strong threaded mechanism typical for early 20th century necklaces. Testing When gently warmed by rubbing, the beads produce a brief sharp chemical scent that quickly transitions into a soft shampoo-like smell, which is characteristic for aged celluloid materials. Based on these observations and the tests performed, it can be reasonably assumed that the material is celluloid – one of the earliest synthetic plastics ever produced.
