I found this at the North of Scotland Archaeology Society (NOSAS) blog [here].
There's actually two cists next to each other. The rectangular one has a flexed body with no grave goods, the oval one next to it only has grave goods with no body. Since they appear to be contemporary, it's theoretically possible the grave goods were purposefully separated from the body or inserted after the body was buried.

The bracer survived burial so given it's bright appearance it must either ceramic or stone. Most bracers in the Isles are greenstone, slate or a reddish stone.
