The necklace measures approximately 20 and 1/8 inches long, from end to end, and should fit at about 20 and 1/16 inches long, closed. The beaded "chain" measures on average just over about 1/8 of an inch, or approximately 3.5 millimeters, wide. Stamped, "925", on the spring ring clasp.
The pendant measures just under approximately 2 and 1/4 inches high, bale included, by just under approximately 1/2 of an inch, or about 12.5 millimeters, wide, band roughly 1/2 of an inch deep. The bale opening is just under about 3/8 of an inch, or approximately 9.5 millimeters, wide. (Included you'll see a US Quarter in the photographs, for the measurement-challenged and ruler-averse.) Stamped, "Sterling", on the back, unsigned, unless the bale stamps are a picto mark. Combined weight is approximately 42.15 grams, which includes 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 visible damage to the stone or beads. The clasp works well and is secure. Hand polished, but it's always possible that some tarnish remains in addition to desirable patina intentionally preserved. This is a handmade item which will not be machine-perfect in any way.
A striking, chunky but highly detailed, naturally colorful vintage Artisan Sterling silver w/ gold and gemstones necklace. Really beautiful depth and so many little handcrafted touches.
