It looks to me like the long lost "Eye of Shivata" from the "Temple of Brahmapurian". Said to have been spewed from the eternal fires at the creation of the world it is supposed to give the wearer special powers. (Women will swoon at his approach, for example) However, if it should be attached to " coverings of the lower body that do not permit of free access to the spirit of the winds" then he who commits such a transgression shall be " cursed even unto eternity".
The story goes that in 1842, after quelling the uprising in Rajipanji, Captain Archibald 'Fanny' Featherstonehaugh of the 212th Highland Light Infantry found the ruins of the temple. Inside was an idol with the Eye of Shivata in the centre of its head. Captain Fanny prised the jewel out and caught up with his regiment. That evening he was given a pair of cotton trousers by one of the Indian orderlies as his uniform was needing repair. He used the 'eye' to secure his trousers as there were no other means to do so. That night it rained heavily and rain got into the good Captain's tent, soaking him though. 'Fanny' was oblivious, having downed not a few pink gins afore bed.
In the morning loud screams were heard emanating from his tent. Sergeant Andrew McAndrew rushed in to find the Captain in agony. The trousers had shrunk and were crushing his nether parts. Swiftly McAndrew siezed the jewel, thus releasing the pressure, and flung the accursed gem out of the tent, where it fell into the swift flowing river. The curse of Shivata has struck again!!
Captain Featherstonehaugh recovered, but he had no offspring and could never dance the foxtrot. The natives considered the jewel was lost for ever ... until now?
On the other hand it could just be a really neat accesory for your kilt ;)
