This engraved gem is magicked so as to appear to be a gem of small value. 

If any character claims it as his or her own, he or she will contract a terrible rotting disease, a form of leprosy which can be removed only by application of a remove curse spell followed by a cure disease and then a heal or limited wish or wish spell. 

The rotting can also be countered by the crushing of a periapt of health and sprinkling of the dust thereof upon the afflicted character. 

Otherwise, the afflicted loses 1 point each of Dexterity and Constitution and Charisma per week beginning 1 week after claiming the item, and when any score reaches 0, the character is dead. 

Each point lost due to the disease will be permanent regardless of subsequent removal of the affliction.
