Stalwart Gem Lab & Mogok Crystal - Myanmar

Is it free to checkor consult if the ruby i bought is real or fake? I bought a ring today from myanmar gem musuem but i wanna know if its real or fake. If its free i would like to go there timorrow to check my ring if the stone they use is real or not. I wanna take it back to the shop where i bought.
