This circular brooch is crafted in 14 karat white gold, measuring 3 inches in diameter. It centers the initial "M" in fancy script lined with bead set round blue stones. This part of the brooch is made up of Palladium. The perimeter of the brooch has a lacy filigree design accented with evenly spaced, larger bead blue stone set with what I believe to be blue moissanite stones but I don't have a gemstone tester that states which gemstone it is. It was taken to a jeweler & they said that is what it tested as. The back of the brooch has a straight pin stem and locking hook clasp stamped, "14K". Weight: 26 grams. This brooch has been tested and verified by a jeweler to have a frame build in 14k. If you have any questions or concerns please let me know. Thank you and happy shopping
