This is a pretty piece of true damascene. It is 1 5/6 wide and 1 1/4 inch high. This damascene pin brooch has very well-crafted etching and insertion of the gold and silver pieces. It has a trombone clasp, which makes me think it was made in France. It has no maker's marks to tell us origin. It is in excellent condition, on both the front and the back. The design on this is intricate and has a cross motif.
From Wikipedia: "Damascening is the art of inlaying different metals into one another—typically, gold or silver into a darkly oxidized steel background—to produce intricate patterns similar to niello. The English term comes from a perceived resemblance to the rich tapestry patterns of damask silk.”
Also from the internet: "When I visited the workshop in Spain, I saw artisans hand etching designs into the darkened metal. Once the designs were completed, they applied silver and gold foil from large spools into the crevices, again by hand. The result is striking and beautiful. Some of the designs use yellow gold, rose gold, and silver to create a lovely color pattern.
Fine, handcrafted damascene jewelry is decorated with 18K or 24K gold and/or silver foil. When purchased from a shop, this will be noted, as shown on the jewelry cards in the photos. Vintage damascene jewelry and damascene jewelry produced today will have the same characteristics, as this jewelry was and still is made by hand."
