I love antique keys and collect them, these keys are made from a 19th century jewel box key in my collection. Handmade in sterling silver and suspended on a sterling silver chain. The key was made in my UK Dorset studio and hallmarked in the London Goldsmiths Assay Office.
The key measures from top of key to bottom of key 29mm High x 11mm wide x 4mm deep.  The silver chain measures  500m  from end to end.
