buy Gray Kingsburg jewelry is very rare . The vintage jewelry site nasvet.com includes as much information as I have ever found about the company and also photos of several Gray Kingsburg jewelry pieces, including this exact brooch.
This unique piece is very three-dimensional, having a round base to which are fastened eight pillow-like, pierce-work settings for the blue cabochon rhinestones. I do not know what the metal is but I think it is brass, gilded on the front side.
The brooch measures 2.2 inches in diameter and .4 inches deep. Photos 6 to 8 draw your attention to a distortion in the lower rim of the piece where it is slightly bent in. The metal is very strong and not easily bent back so I have not tried to fix it. Aside from that, the brooch is in excellent condition, very weighty, and with a strong secure clasp.
