1960s Delft Pottery White & Blue 925 Silver Small Dutch Windmill Shorline Pin

Lovely petite round white & blue Delft pottery cabochon center with a scene of a windmill set in 835 silver rope frame pin circa late 1950's, early 1960's. Hallmarked 925 (I believe that what is says - its very small & tough to read) on the c-clasp. It measures 1-3/8 inches in diameter. Preloved, the pin is in very good condition with small scratches. The Delft signature has worn off & only the D remains. No nicks, chips or cracks in the pottery. The silver needs to be cleaned & polished. The pin & c-clasp are secure. Consider the pictures to be part of the description. Don’t hesitate to ask any questions.
