Provenance sometimes sways the price of Diamond jewelry, so whenever possible sellers will emphasize an esteemed previous owner. But one man’s selling a stone he insists was worn by Satan herself.

She’s his ex.

The rock was mounted on her engagement ring, which he offered after three years of courtship. Only then did her true identity reveal itself. As he explains, her “rage, it boiled, her eyes glazed over and her head span 360 degrees on a daily basis and she spewed venomous insults toward my aching heart.”

Possibly after breaking an especially big mirror, he endured seven years before walking out. “Now I’m happy,” he declares.

Offering no details on colour, clarity or cut, the seller simply describes the item as one-quarter carat on a gold ring, “size fat.” He does provide this disclaimer: “Although worn by Satan herself it does not possess any magical powers or any black magic. Cannot guarantee it’s 100% safe to be worn by those of faith.”

He adds: “Serious offers only.”

Past ownership by royalty, aristocrats or celebrities can enhance a diamond’s value. Last May the 14.62-carat Oppenheimer Blue broke auction records with a $58.25-million price possibly influenced by its association with De Beers bigshot Sir Philip Oppenheimer. The previous month, however, a 9.54-carat stone associated with a phenomenally famous actor-turned-diplomat disappointed auctioneers. Having hoped for $25 million to $35 million, Sotheby’s rejected a $22-million bid for the Shirley Temple Blue diamond.
