This is a beautiful set of earrings, ring and a pin made by Sarah Coventry. It is called Kathleen and dates from the 1960s. The pin is a book piece and appears on page 67 and the back cover of Fine Fashion Jewelry From Sarah Coventry by Jennifer A Lindbeck. The flower shaped pin has a large center flatback round rhinestone in emerald green and is surrounded by 3 clear rhinestones on each petal. The pin and rhinestones are all in great shape, there are no dead or damaged stones. The pin is 50mm in diameter. The back of the pin is signed SARAHCOV with the copyright symbol. The fantastic earrings also have the same emerald green rhinestone, but this time it is a slightly square shape surrounded by clear rhinestones. They are about 24mm in diameter. The earrings are clip back, and have fantastic comfort cushions on the clips They are signed SARAH COV PAT. PEND on the clip. The ring is adjustable. It has the same green stone as the ring, but does have a small bit of foil damage to one corner of the large green stone. It is not drastic and does not take away from the beauty of the ring. The ring is singed SARAH COV with the copyright symbol on the band. 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. Thse items are vintage and is sold as is. I'd be happy to answer any questions you have.
