This is a gorgeous demi parure made by Sarah Coventry. It is called Vienna and dates from the 1960s. Both items are book pieces. The pin appears on page 68 and the bracelet appears on page 92 of Fine Fashion Jewelry From Sarah Coventry by Jennifer A Lindbeck. The cresent shaped pin has large black marquise rhinestones and clear round rhinestones. The pin and rhinestones are all in great shape, there are no dead or damaged stones. The pin is 70mm by 55mm. The back of the pin is signed SARAHCOV with the copyright symbol. The bracelet also has the same black marquise rhinestones and clear round rhinestones. The bracelet is about 7 inches in length. It is signed SARAH COV on the clasp. The bracelets safety chain and clasp are intact and working. The stones are set in silver-toned metal, which is possibly Rhodium plated. I could see no metal damage on any of the pieces. They really sparkle.
