Enchants/Gems get scaled up or down depending on what character their transferred to and from. 160 Agility gem made on a level 90 becomes a 16 agility gem on an 80 for example, yet still can't be used due to ilvl restriction...
Looks like all tooltips scale for said items, so you can link back and forth to different level characters to find out stats.
