JEWELLERY worth more than £50,000 was seized during a series of police raids.
Officers swooped on homes in Bolton, Bury, Wigan, Salford and Skelmersdale in December.
The raids were aimed at tackling serious organised crime across Greater Manchester.
Watches believed to be worth more than £20,000 and a diamond encrusted ring were among items recovered, as well as £32,000 in cash and a bicycle.
A home in Chew Moor, Westhoughton, and one in Kearsley were raided as part of the operation involving about 200 officers.
Seven people were charged following the raids.
A woman arrested at a Bolton home on suspicion of money laundering has been bailed along with two people arrested at a Ramsbottom home also on suspicion of money laundering.
They have been bailed until February 18.
Project Gulf, which planned the operation, was launched in 2010 to investigate all areas of a suspected criminal’s life.
Anyone with information can call police on 101 or Crimestoppers on 0800 555111.
