Victim fears inside job as burglars steal £1.5 million of jewellery She said: "I was upstairs and came down to the ground floor to watch television. While I was downstairs for only around 20 minutes, someone came in. They knew the combination of the safe so it must have been an inside job. They took everything. Usually it's all in the bank, but we'd just come back from holiday. All that jewellery is never in the house. I am still quite shaken. It doesn't seem fair because I don't go around dripping with jewellery. No one would have guessed I had all those valuables in the house. The thief knew it was there so it must have been a workman or someone like that. It took 45 minutes before the police arrived, I couldn't believe it. The police have been around to do DNA tests but nothing's turned up so far. Among the other items stolen was an 18ct yellow gold horse head bangle, with ruby eyes and 53 diamonds set in the headband and mane. There was also a platinum and diamond ring with a 3.78 carat blue sapphire centre stone and a platinum and diamond cluster ring with a ruby centre stone. Other pieces taken in the raid included a necklace of South Sea pearls with a white metal clasp set with nine diamonds and a platinum and diamond cross set with 11 round brilliant cut diamonds. The burglary took place on the evening of Saturday 18 October as the couple watched television and they were not aware at the time that anyone had entered their home. Detective Constable Nick Howard, from Westminster police, said: "They had knowledge of the property and of the couple's movements. They were watching TV and had no idea about the raid until after it had happened. There was no break-in and the victims were not threatened. It is a townhouse - not palatial or anything like that. The items are of great sentimental value. The most expensive was a 7.75 carat marquise diamond ring which is worth several hundred thousand pounds. The woman also lost her wedding ring which would be priceless to her. He added: "We are keen to speak to anyone who saw anything suspicious or who was in the area at the time and may be able to assist us. These items are very distinctive and would be immediately recognisable.
