This brooch was made by the Gerry's Jewelry Company who created costume jewelry from the early 1950s through to 1996 when they went out of business. One of the items they're best known for is Christmas brooches and pins.
This sweet Christmas tree dates circa 1980s and measures approximately 5 x 3.6 cm. It is in excellent vintage condition.
I sourced this vintage brooch in the USA.
