I wish you could have provided this info earlier. That stone is "graywacke", possibly from German "Grauwacke", and the Turkish name for it is "grovak"

One of specialists ruggested that it is a "greywacke" - a kind a stone. Funny, but in Russian it is "grauvakka", so maybe they just invented the word by addding "li" to a Russian word at the end to make it an Azeri adjective. And they also made a spelling error, it should have been "grauvakkali".
Thanks to everybody who responded!

does not resemble turkish the least. still, i searched some possible variations trying to adapt it to turkish spelling in a couple of ways, but to no avail. i think the answer should be found in azeri again.
