The relics of Buddha are now in Chile on display. Here is an interesting look at the story behind the relics.
bq. “The mystery behind relic-worship:”:http://www.dailynews.lk/2003/07/09/fea06.html What remained after the Buddha’s body was burnt “were only the bones” which are explained as “the indestructible substance that remains unburnt in the ashes of Buddhas and Arahants.” Accordingly, in addition to the seven great relics that remained unburnt, which were the four canine teeth, the two collarbones and the frontal bone, the other unburnable dhatus that remained scattered around the burnt up pyre were of the size of mustard seeds (Digha Commentary II, 604).
