We offer you this sweet little oval pin/pendant framed in 1/20 12K gold filled metal with an embossed scrolling pattern and a central oval flat cabochon stone in a medium green color. To be honest I have not been able to determine what the stone is, but I can tell you that it is mottled and translucent when held to the light. I might be a low grade of jadeite, but I won't claim that for it as I'm not sure. Subsequent to posting a lady contacted me to suggest that this stone may be Connemara marble from Ireland which is possible, but I am not claiming that to be the case as I'm not sure. It is small in size measuring 1 5/16th" H (with bale extended) and 1 1/8" H with it retracted X 1" wide and 1/4" deep (front to back). The piece is in good, used condition with a retractable bale at the top so that you can wear it as a pendant and a fully functioning pin mechanism with a safety clasp also in good order. The piece dates from the 1890-1910 period which includes the very late Victorian era and the start of the Edwardian period when high-collared blouses were all the style and a small pin in the center of one's collar was a perfect, ladylike accessory. Today it could be worn on a high collar or a hatband or a sweater or whatever way you like. We will ship it to you in a jewelry gift box for storage or giving as you wish.
