I believe this UNUSUAL shaped piece of Thick Polished Baltic? Amber jewelry dates C.1960. Vintage amber pin is a luscious HONEY color and filled with chunky inclusions. The shape of the brooch reminds me of an EYE... top and btm. edges are 'beveled'.
UNIQUE natural amber pin MEASURES ~ 1 7/8 x 1 1/8 Inches and is OVER 1/4 Inch Thick. This piece is direct from a Cape Cod Mass. estate and is in VERY GOOD CONDITION! Retains original embedded metal 2 piece pin stem/clasp securely mounted to the reverse and shows only minute signs of treasured use.
