This singular stone was given as a prize in the murder mystery scavenger hunt some time ago. It was not salable at the gem shop, and, since it was used in an alteration and no longer loose, no longer fits my personal definition of sparkly. However, due to its historic value, its entry will not be removed from these documents.
a Dragon's Tear diamond
There is other gem that I know of as being a prize in a contest that isn't also available elsewhere.
an enormous uncut diamond
This gigantic diamond could easily fill a Gor'Tog's palm.
