Ole Lynggaard, clasp in 18K gold with 4 pieces of stone necklace
The lock's diameter approximately 10.5 mm, weight approximately 2.8 grams, the stones' diameter approximately 10 mm, lengths excluding the lock between approximately 43.5-49 cm, a matching collier with stones approximately 8 mm in diameter with pins that fit the lock, likely not Ole Lynggaard.
Minor signs of use.
