This necklace can be worn up to 23" in length. The turquoise is showing up bluer in the pics, it actually has a greenish tint to it. The pendant portion of this necklace is .925 layered sterling silver. The chain, jump rings and lobster claw clasp are stainless steel. The earrings measure 1 1/2" including the stainless-steel wire hook closure. I did arts and crafts shows for 12+ years. I had to call it quits with an extensive inventory still in my possession.
