The thieves struck at the saleroom's premises in Bankhead Medway, in the west of the city, in the early hours of Saturday, December 7.
The jewellery taken was in a cabinet in the retail department, so Shapes' art and antiques sale including silver and jewellery went ahead as normal that day.
Det Con Joyce Gunderson from Police Scotland said: "Anyone who believes they have been offered the stolen items for sale, or has any other information that can assist our inquiries, should get in touch."
Anyone with information should contact Police Scotland on 101, or call Crimestoppers anonymously on
0800 555111.
