lab is for very late game ranking players who have over 4k+ small stones (likely 2k+ medium stones, etc.) from ranking advanced EH, not nearly enough orbs, and no idea what to do with them. The rates are pretty awful though. you won't be converting except to fix very major imbalances in your stone stocks
