u/GT_REDHOOD_

This stone looked abit different from the normal white topaz in this lot, has a light yellowish colour it doesn't scratch by quartz but a rhodolite garnet was able to scratch it. It feels abit light on the hand and the shiny part looks like a cleavage. Do yall have any idea what this stone is or is it just another topaz?

Its has a heavy feel on the hand and weighs about 320cts or 60 grams. It has a blue fluorescence and it canbe scratched with a diamond plate. Has a rough outer surface.
