a thread of silver twist

[Antonio J.]

Hola. ¿Qué significa "silver twist" en la frase siguiente?: All the letters and papers in the oak cabinet related to matters stale as the deluge, with the exception, indeed, of some few notes from Geoffrey´s young wife, and a lock of her hair tied with a thread of silver twist.
El texto pertence a la novela The haunted house at Latchford, publicada en 1872.
Gracias por vuestra ayuda.
