Years ago I delved deep into lapidary. Agate is cryptocrystalline quarts. It takes a high polish, and the patterns and colors are endless. Creating a "spoon" from a "non precious" stone has never occurred to me until now. However,,, beads (used for streamers ) have had me wondering....Would a "fake opal" bead trigger more strikes? Would a fake "ruby" bead... bend the light in such a way that makes it more appealing to a fish then a glass bead? Of course using real gemstones is ludicrous, however the "fake" gem stone beads available today are quite remarkable, and quite affordable. When humans see a red stone set in a ring, there is a huge difference in their reaction to a glass fake and a quality ruby. The difference between a good fake and a real ruby.. not so much. Colored gem stones have mesmerizing effects on humans, perhaps the same is true for trout.????
