This beautiful handcrafted pendant necklace and earring set features an oblong-shaped apple green Chrysoprase natural hand carved cat accented with apple green Chrysoprase nugget separated by sterling silver beads. The set is made of 925 sterling silver and comes with a seller warranty. The necklace is 18.4 inches long and the earrings are designed for pierced ears with a choice of lever back, stud or french hook closure upon request or clip-ons. The design is unique and stylish, perfect for any occasion.  The set is nickel-free and made in the United States.  Natural Chrysoprase is a form of Chalcedony and is the birthstone for May.  It has traditionally symbolized happiness, enterprise and prudence.  It is a powerful stone that brings good fortune and prosperity.  I was surprised to find that it has a bit of nickel in it.  I am highly allergic to nickel and had no problems touching this stone.
