A West Wickham woman was tied up in her own home during a robbery.
The 48-year-old answered a knock at her door on November 27 at 10.45am.
Three men forced their way into the house, in Hayes Lane, after she opened the door.
After tying her up, they stole a number of distinctive designer bags and some jewellery.
Among the items stolen was a 2.75 carat diamond solitaire ring worth £10,000, and a white rubber strapped Cartier Watch valued at £1,000.
Also taken were a £2,000 pair of diamond square screw back stud earrings, and a diamond studded cross pendant with a white gold chain, worth £7,000.
Bags taken included a Louis Vuitton messenger bag, an Alexander McQueen pony skin clutch bag and a grey Anya Hind March tote bag.
The robbers fled the scene in the victim's black Mercedes, which was found abandoned the next day in The Drive, West Wickham.
One of the suspects is described as a white man in his mid-20s, of stocky build, around 5ft 8in.
He was slightly overweight, had a clean shaven round face and brown hair.
The second man is described as a light skinned black man, about 5ft 6in and in his mid-30s.
He is of slim build and spoke with a local London accent.
He was wearing a knitted black balaclava with black gloves and brand new black boots.
The third man is thought to be a mixed race black man, aged in his early 30s, around 6ft 1in.
He also spoke with a local London accent and had a stocking over his face.
Anyone with any information should contact Detective Constable Dan Simpson at Bromley police's CID on 101 or Crimestoppers anonymously on 0800 555111.
