3 piece Sterling, Shell (Delicate Detail) Cameo Lot. Necklaces + Pendants. Shell Cameo portrait, metal unmarked (gold tone). 18" chain, frame is 5/8" tall I like this piece because the facial features are delicate and well done (the pic with the penny was taken from the side instead of straight overhead to capture this). Sterling Silver Necklace Pendant Blue Gemstone Marked "925 INDI PA Italy" Good used condition. Clear, blue gemstone. Necklace marked "925 Italy". Pendant marked "925" on the bail, and "INDI PA" on the back (PA upside down). 17.5" necklace. Pendant is 1.5" tall from top to bottom edge of gemstone. Artist Signed Sterling Necklace 17.5" Pendant 1" Marked 925 Black Red Stones. Very Good used condition. Center stone is black, above and below the stones are red. Pendant is 1" tall, 5/8" wide. The artist signature is easier to read with an enlarged photo (provided). Above center, you can clearly see an "M" and another letter or symbol, may be an upside down "C". Below center is "925" for the silver. The clasp on the necklace is also marked "Sterling". Necklace is the type that looks like a spiral.
