POLICE have issued an appeal to the public to help recover stolen jewellery worth more than £8,000.
The 17 items of jewellery, which include gold and diamond rings and broaches, were taken from a shop on High Street, in Old Town.
Police say that at around 2.30pm on Wednesday August 15, a man entered the shop and began chatting to the owner, asking numerous questions about items on display.
The offender, who police believe was from out of the area and was with another man, then asked to see inside a locked cabinet.
Once the owner was distracted the offender - described as white, slim, around six foot tall, aged between 25 and 30 with short mousey brown hair and wearing baggy jeans and a light coloured v-neck jumper - picked up the items of jewellery before leaving the store.
Amongst the items taken was a rectangular, 18 carat (ct) white gold broach set with two old cut brilliant diamonds worth £2,150 and an 18ct white gold pendant shaped ring with large diamonds and sapphires worth £1,250.
Police are asking members of the public to be vigilant if they are offered jewellery in the lead up to the Christmas season.
They are also appealing for witnesses who may have noticed anyone acting suspiciously in the area at the time of the robbery.
