This lovely little mourning brooch has a rare, oversized diamond shaped crystal (possibly paste?) inlaid within a black glass, faceted oval. The hard to see chipping and gaps of the inlay led us to believe this was handmade and that it could be antique. An early securing c clasp puts our guess at early 1920s or 1930s. It looks like brass, but could be gold toned metal. A beautiful addition to any collection. Please see photos for more detail.
