This is a lovely Art Deco stick pin, which originates from Germany, with the back stamped “333” for solid 8 carat.
The pin head has a typical Art Deco design and is set with a red stone, presumably a ruby, which is 4mm long and 2mm wide.
Difficult to date precisely, but it is certainly a genuine period piece, Circa. 1910’s/20’s.
The pin head is 1.1cm high at its highest point and 1/1cm wide and the entire pin is 6.3cm long.
It is in excellent overall condition, with no damage/repair or obvious signs of wear.
A collectors item, as well as a very wearable piece of antique jewellery.
