CHICAGO – Jewelry collectors who don’t mind if their gems have a shady past soon will get the chance to bid on a stash of valuables found in the home of reputed mobster Frank Calabrese Sr.

Federal agents raided Calabrese’s home in the Chicago suburb of Oak Brook two years ago and found a hoard of jewelry, guns and cash in a secret compartment behind a family portrait.

Now, the Chicago Sun-Times reports an online auction house in Texas plans to sell the items, which are valued at more than $500,000 and include more than 250 loose diamonds, earrings, engagement rings, luxury watches and other jewelry.
