Richard Mackenzie Matthews made his first court appearance since police say he expelled a $20,000 diamond over the weekend.
The 52-year-old appeared via video link from the Windsor jail on Tuesday morning, dressed in an orange jumpsuit.
He showed no emotion and didn't speak during the appearance, but did talk to his lawyer in private over the phone. His case has been put over to Monday.
Matthews is alleged to have swallowed the 1.7-carat stone at Precision Jewellers, after switching it for a fake.
He was ordered to stay in custody until the real diamond was found and police say he expelled the missing gem Saturday.
Police say he also passed a cubic zirconia — a low-cost diamond substitute — and they believe there is one more of those to come.
He is charged with theft and breach of court conditions, and is also wanted on warrants in Toronto.
