Rough Ruby

Rough Rubies are the hardest to get Rough Gem out of all. They are randomly sent by a person who owns a Dino Bone Sticker Module to a person on the module owner's friendlist. 10 are needed to make the Jeweled Triceratops Masterpiece and 5 to make the seal. After that you won't find any use of them other than buying a few loops and stickers.
