A two-carat diamond has been found nearly two years after a man nabbed it from a jewelry store. The catch: the colorless stone which is estimated to be worth $25,000 has been found stuck in the shower drain at the same prison where the man accused of stealing it was serving his sentence.

Bret Allen Langford, 39, was arrested in April 2005 for stealing the diamond at a Jewelry Express store. The diamond had never been recovered, until this week, when an investigator representing Langford told jail officials to search the jailhouse drains.

A search found the rock wedged in a screen beneath one of the facility's shower stalls, according to the Los Angeles times, and the journey of stone was apparently clear after Langford's confession.

Langford said that he used to swallow and regurgitate the rock each time he was transferred to a different prison. But 14 months ago, when he was just about to be searched, he threw the diamond into a shower stall, which fell down the drain, and apparently was caught by a screen in the shower drain.

Langford's trial is set to begin May 7 and authorities expect to feature the diamond as a piece of evidence. The rock will then be cleaned and returned to the store.
