This is a lovely, silver (tested but unmarked) and paste St. Espirit Pendant. It comes in two pieces; the bird can be detached from the upper bow. The piece is circa 1880, and it weighs 9.91 grams. It is 1 and 1/2 inches North to South, and 1 and 1/8 inches East to West. This is a lovely example of a Victorian paste St Espirit.
