Solid Silver Trinket Box On Bum Feet And Converts To A Brooch - Silver Maker JSJ

Another lovely Silver item I bought at Malvern Hills Antiques Fair about 5 years ago.
Makers Marks: JSJ with an anchor, lion and the letter R.
Again this sits in a cabinet and is not used.
The lid coverts to being a lovely brooch - quite novel I thought when I bought it.
The stone (not sure if glass or what it is actually) is a tan colour going into orange when held up to the sun light. No marks or blemishes.
There is a very slight pin prick dent as you can see in picture 3 top right hand side on the base but not noticeable when it is sat down. Lovely item but again just something I will never used.
and Thank-you for looking.
Will be sent registered post.
