Measurements, west to east 2 1/4", north to south 1 3/4". depth of frame, about 3/8". Condition, Good, a very small chip to the side of the jasper on the edge of the front of the frame, and a slightly larger one to the reverse of the jasper, again on the edge.( these chips are extremely small, and only visible under very close inspection). The dark marks to the back of the frame are solder marks where the parts of the frame were joined together ( a common technique on this type of frame ) A good example of an early Victorian plaque brooch, having a good decorated repousse frame ( a technique very popular in the 1840s, and set with a jasper plaque ( jewellery set with specimen stones was very popular during this period, due to the strong interest in natural history).
