YELLOW VASE - CRYSTAL OR CUT GLASS?

KNOW ANYTHING ABOUT IT? IT IS VERY HEAVY. IT SEEMS TO RING LIKE CRYSTAL. I D0NT THINK THE COLOR IS ON THE SURFACE I THING IT GOES THROUGH. THE GLASS IS VERY CLEAR AND TRANSPARENT. IT IS NOT CLOUDY LIKE DEPRESSION GLASS. THE COLOR IS YELLOW. IT IS NOT GREEN YELLOW LIKE VASALINE GLASS OR BROWN LIKE AMBER GLASS. THERE ARE NOT MARKINGS. ITS ABOUT 10” TALL
