This collection came to me as part of an estate. Vintage Brooch-and I have no idea what this is supposed to represent. There are two tools, crossed. Gardening maybe? And the stone- your guess is as goods as mine. The woman who made this was fascinated by gemstones, and although I am not a gemologist, I usually know which is what. This one - - ? Approx 2.5" high by 1.5" wide.
