Real gemstones, rare billiards vtg or antique stick pin, VGUC

Quirky, rare, vintage or antique billiards-themed stick pin! Three inches long with cue sticks and gemstone balls at one end, and a barrel-shaped clutch on the other. The clutch is a replacement, and the only part of this which is magnetic. There are no hallmarks, so we'll call this undetermined non-magnetic metal goldtone. As you can see, long wave UV light (my blacklight) shows at least 2 of the 3 stones to be real gemstones. That gorgeous brightly colored stone is most likely a real ruby, whether manmade or natural. To my knowledge, this pin predates moissonite by years, so that blue glow is likely a natural diamond. Since many diamonds don't glow in UV, that third stone might still be a diamond. Minor wear, but overall Very Good Used Condition! A unique beauty!
