Wally knows his rocks. Real turquois is quite soft and cuts with a sharp detail gouge and power sands flat--only if you use epoxy which is 4 times easier to cut than CA. It doesn't tend to stand up proud like CA. I work the stuff down with cheap HF air grinders and 180--300 grit discs. Epoxy also does not stain light colored wood like CA is famous for. For a contrast try black dyed epoxy/turquois paste for repairs. When sanded down it's different. A fine cut file works well on curved surfaces.
