$27,000 diamond ring swallowed by alleged jewel thief Mark Watts set to go to auction Mark William Watts appears at Brisbane Magistrates Court on charges relating to stealing rings from an Indooroopilly jeweller and swallowing them. THE saga of the swallowed diamond ring will enter another phase this afternoon when the auction of the jewel begins. The 1.53-carat yellow diamond and platinum ring has 28 white diamonds and is valued at $27,080.00. Bidding on the ring will get under way at 5pm. The auction will run online until 9pm on December 23 with all proceeds going to the Leukaemia Foundation of Queensland. The ring was one of two swallowed by Mark Watts on November 29 when he allegedly stole them from Crown Family Jewels at Indooroopilly Shopping Centre. When he was cornered by staff in a nearby pharmacy Watts swallowed the rings. The ring that is to be auctioned was extracted from Watts via colonoscopy on December 9 after police waited for him to relieve himself of the jewels. Police mistakenly threw out the second ring, that was for sale for $35,000, in waste bags.
