To their credit, some sellers will actually tell you they are selling turquoise Howlite (turquoise, referring to the color in this case). Obviously this is dyed stone because Howlite is white in its natural state. If this is what you like and what you want, then by all means buy it! Buy what you are attracted to. Obviously, the seller is being honest. Just make sure you are not paying authentic turquoise prices for an inexpensive stone that has been dyed.
