Police Scotland is appealing for witnesses following the high value break-in on 25 April.
A property on Belwood Road, in north west Penicuik, was broken into between 12:15 pm and 6:15 pm on Tuesday 25 April.
Upon their return to the property, the homeowner discovered that a large quantity of jewellery including, cufflinks, necklaces, pendants, bracelants, earrings, bracelets, broaches and watches had been stolen from within.
The value of the stolen jewellery is believed to be around £30,000, though they have an even higher sentimental value.
Inquiries are continuing to identify those responsible and recover these items and anyone with information is asked to contact the Police immediately.
Constable Scott Clark from the Proactive Unit said:
As you can imagine, the victim is utterly devastated at the theft of these pieces of jewellery, which hold significant financial and sentimental value.
As part of our inquiries we would urge anyone who remembers seeing any suspicious activity around Martyrs Cross on Tuesday afternoon or evening to contact police immediately.
We will be engaging with a number of second hand retailers to locate the stolen goods, but I would also request that members of the public who are approached and asked to buy any such jewellery should decline and get in touch with us.
If you have any information that may aid investigations, you are asked to contact the Proactive Unit in Musselburgh via the non-emergency number 101, quoting incident number 3006 of the 25th April 2017, or you can report this anonymously to Crimestoppers via 0800 555 111.
