This is described on page 38 and 39 of the manual (pdf link above).
Generally you would leave one teleporter stone at your home base or beside your favourite merchants. The other you carry with you and when you need to sleep, buy stuff or get rid of loot, drop and use it, then do what you need to, use the teleporter stone at your base to get back where you left off, pick up that teleporter stone and continue.
If you have one teleporter stone on the ground you can just click on the other in your inventory to use it, if you don't need to get back that way (otherwise you can drop it and then click on it to use).
With one teleporter stone in your inventory, there are 3 icons available when you click on the skill menu button, to 'drop', 'use', or 'drop and use' the teleporter stone.
As a shortcut for picking up a teleporter stone (or anything else which does not have a default action of being picked up when clicked on) you can drag and drop it onto the menu interface along the bottom of the screen, rather than having to open your inventory.
