The necklace measures approximately 21 inches long, from end to end, and should fit at about 20 and 5/8 inches long, closed. The amethyst portion of the beaded "chain" measures just over about 5/16 of an inch, or approximately 8 millimeters, and the pearls are approximately 1/4 of an inch, or about 6.35 millimeters, wide.
The circular pendant portion measures approximately 1 and 7/8 inches high, by about 1 and 9/16 inches wide, and roughly 3/8 of an inch deep. (Included there's a US Quarter in the photographs, for the measurement-challenged and ruler-averse.) Stamped, "925", on the back, unsigned. Weight is approximately 59 grams, which includes mainly the stone weight, of course.
This necklace is in very good vintage condition. It will have the expected surface scratches and possibly tiny dings to the silver from normal wear. No obvious damage to the stones or pearls. Hand polished, but it's always possible that some tarnish ans or soiling remains.
A very pretty, bold but feminine, vintage Sterling silver and amethyst necklace. Delightful color and unusual style.
