The “rare” items were taken when thieves broke into an Eildon home, via a side door, between 5.30pm and 8.30pm on December 17.
Police have now released images of the items.
Detective Senior Constable Aaron Diwell said they were fairly distinctive pieces of jewellery.
“They’re high end, rare pieces, and they hold an incredible amount of sentimental value,” Diwell said.

“These are very precious pieces of jewellery, and we are very keen to reunite them with their rightful owner, particularly this close to Christmas.”
Police are particularly interested in speaking to anyone who might have seen the pieces pop up for re-sale on online websites.
Anyone who recognises the jewellery or has any information is urged to contact Crime Stoppers on 1800 333 000.
