This beetle is in very good condition (though the pin is slightly bent), and is set in unmarked but tested 14k rose gold. The beetle itself is 9/16” x 7/16” at the widest point, and is held firmly in place by 4 prongs. The whole thing is 2-3/4” long. The Victorians loved to use all kinds of organic things in their jewelry, including real beetles. This particular type seems to have been a favorite. They are very collectible! We have been told they are late Victorian, so probably Circa 1880. The photos are part of the description; please examine them carefully. Thanks! Shipping, handling & insurance within the USA included.
