VIENNA – A man turning dirt in his back yard stumbled onto buried treasure — hundreds of pieces of centuries-old jewelry and other precious objects that Austrian authorities described Friday as a fairy-tale find. Austria's department in charge of national antiquities said the trove consists of more than 200 rings, brooches, ornate belt buckles, gold-plated silver plates and other pieces or fragments, many encrusted with pearls, fossilized coral and other ornaments. It says the objects are about 650 years old and are being evaluated for their provenance and worth.
