Looted precious treasure: A deep blue tear shaped gemstone, named for the brightly sparkling motes seen in high quality varieties. A merchant might pay several coin for this item.
I noticed that there are a series of alphabetically named stones: Karana Tear, Lambent Stone, Nightspark. Since they dont fall under collection -I was wondering does someone know if they are used for a quest - maybe collect them as part of a quest.
