This gorgeous old brooch is by Jakob Tostrup of Norway, one of the higher-end silversmiths in the region. It features stunning shades of blue, green and teal, with stylized herons in dramatic black in the foreground.
Measuring 1 7/8" diameter, this large brooch is in very good condition; it has only minor, superficial abrasions to the surface in some places. The back of the brooch is signed "J. Tostrup Monster Beskyttet 925S." The closure is a traditional c-clasp.
