Real or fake turquoise?

I think this might be magnesite or howlite. If you have any nail polish remover, swab a colored area with it and see if it removes any color.

i just try it with nail polish remover no color on the cotton
looks like Jason the master in the another post said is stabilized turquoise

anyway thank u for your advice Mr

Hi, Pretty sure this is dyed howlite. It even looks like it was dyed after cutting. Some countries are using tidybowl type water dyes to color stones. These don’t tend to rub off because they are more of a stain than a colorant. Think of a wine stain on your nice marble countertop !
