Lambton County OPP are asking for assistance from the public in a break-and-enter investigation in Grand Bend.
They say it appears suspects forced their way into the Grand Bend home through the front door on July 3 when no one was home.
They went into the master bedroom and stole several pieces of expensive jewelry.
The stolen items included gold chains, a diamond ring and diamond earrings, a Lady Di style diamond pendant, gold bangles, a pearl bracelet, and a Rolex watch.
Police say the total value of the stolen jewelry is estimated at more than $35,000.
Anyone with information that could help the OPP recovery the jewelry and identify suspects is asked to contact the OPP, or Sarnia-Lambton Crime Stoppers.
