What do Pure stones and Black stones look like? Just an odd question 'cause I see an option in AH but they're never there.

This is just my guess but its either they are soo rare hardly anyone seen them or they use it already or its just simply not out yet for some odd reason.

Those stones was long time ago before Big patch :) as i remeber TW never had those But as they took game from Kr NTL they took all database.....
Pure stones and black stones was for upgrade gear's and weps
Pure stones is same as we Have U** purple or green ( random 1-3 enchant)
Black stones is downgrade stone
To sum everything Those stones was doing same option as now we have U**
