For your consideration, this Wonderful, Detailed, Handcrafted Vintage Southwest Hand Stamped Sterling Silver Turtle or Tortoise Pin or Brooch.
From the tip of the nose to the tip of the tail, the piece measures just over approximately 1 and 7/8 inches wide, by just over approximately 3/4 of an inch, or about 19.5 millimeters, high, and just under roughly 1/16 of an inch, or about 1.5 millimeters, thick, not including the pinback. (Included you'll find a US Quarter in the photographs, for the measurement-challenged and ruler-averse.) Standard locking pinback. Not marked as to content, nor signed, but acid tested as Sterling silver. Weight is approximately 4.24 grams.
This brooch is in very nice vintage condition, though it will have the expected light surface scratches and possibly a few tiny dings to the silver from age and normal wear. No bends or creases. There is an acid test mark on the back and some remnants of some writing in sharpie which will come away with polish, if you choose to remove it. Hand polished, but there is likely missed tarnish. The locking pin back works well, and the pin is straight and sharp. This is a handcrafted piece which will not be machine-perfect in any way.
A lovely and unusual example of a vintage Southwestern Artisan Sterling silver turtle pin. Lots of personality and great attention to detail.
