Green Jade 925 Sterling Silver Italy Barrel Slide Necklace Blessing Earring Set

Offering a lovely high-quality sterling silver and jade necklace and earrings set. I do not know if they were made by the same jeweler, however they came into my collection together about 25 years ago, so I'm estimating that is the approximate age of the pieces. Necklace: Sterling silver box chain measures 16 inches long and features a light green jade & silver barrel slide pendant. The jade/silver slide measures 16mm (5/8 inch) long. The necklace clasp is marked 925 Italy and another (makers?) mark that I cannot identify, looks like an "A". Earrings: Sterling silver earrings with genuine Chinese green jade dangles. The post-style earrings have a the Chinese character for "blessing" with light green jade cylindrical dangles and silver end caps. The earrings measure 1 inch long.
