This piece by Albert Weiss was made between 1951 to 1955 based on the maker's mark. It is a choker style and features water drop, or tear drop, style dangling rhinestones strands. While I was unable to determine what materials were used in this specific piece, Albert Weiss was known to use high quality rhinestones and Swarovski crystals in all his pieces. Measurements: about 16 inches long, dangles hang almost 4 inches long Condition Notes: Some darkening/tarnish on the back of the necklace at the tips as shown. Some darkening of the rhinestones in the chain part of the necklace as shown. Main part of necklace is in excellent condition. tags: mid-century modern, 50s, antique, retro, coro, designer, jeweler, feminine, prom, dressy, date night, sleek, chic, fancy, costume, style, classic, clear, white, silver, bridal, going out, girls night, treat yourself, bling, sparkle, 1950s
