43 g.

The locket is 6.5 cm drop from the top of the bale to the base of the locket, and 4 cm wide. It opens well and closes with a snap. 

The chain is 44 cm long and 1 cm wide.

The locket is hallmarked on the bail. The chain is not hallmarked but has tested for silver.

Both pieces are in very good condition.

Thanks for looking.
