This is topaz from katlang, As all of you know that katlang was the best popular source of pink topaz of the world, now the production of this mine is less than before, anyhow we have got some old stock of this material , this is natural color topaz, we have describe this lot as 35% clean, but depend on yield preference i think you can get more clean material in this lot, this is nice lot form katlang mine, so this is a good chance to get this material in small nice lot.thanks
