At the beach this morning another 14 VDI, do I dig it or not, Ah, what the heck what's another bottle cap or pull tab my pouch is already half full with them. Well Suprise, Surprise just a 18k (maybe 21k or 22k, no acid test for) with a ruby or sapphire, tested 18k but color looks more like 21k or 22k. Stamped but I have no idea what it means. Anybody have any thoughts or comments??
