From The Image.Com:
"Clear topaz has little value, and is quite prevalent. Some varieties can be irradiated to various shades of blue, and this acceptable in the trade. Most blue topaz on the market today is irradiated. There is a grayish variety of topaz that is sometimes cut to produce a stone called "champaign" topaz. "

Sorry but this question is impossible to answer simply. Topaz as a mineral "chunk" has little or no commercial value. If, however it is has formed good crystals it can have considerable value as a mineral specimen. Going further if it is good enough to cut into a large stone of the finest colour the value can be huge. Without examining the material or knowing its colour it is impossible to even make an educated guess.
