I believe items ① to ⑤ are amber. I'm not sure about the rest. The condition is not good, with some fittings missing and items needing polishing. I hope you can repurpose them or find some other use for them. * ① to ③ Amber. They have what looks like tree bark inside. Stone dimensions: 4.5 cm long, 2.2 cm wide (at the thickest part), 1.2 cm high. They appear to have been brooches. * ④, ⑤ Amber. They have what looks like tree bark inside. Stone dimensions: 2 cm long, 0.9 cm wide, 0.4 cm high. They appear to have been cufflinks. * ⑥, ⑦ Stone type unknown. Stone dimensions: 3 cm long, 3 cm wide, 1 cm high. They appear to have been bolo ties. * ⑧, ⑨, ⑩ Stone type unknown. Length excluding fasteners: 42 cm. The above measurements are approximate, taken by an amateur.
