Due to the fragile nature of some of the artefacts recovered from the Dunragit sites, specialist conservation was undertaken. These included a ceramic vessel, originally block-lifted on-site from a late Neolithic/Early Bronze Age cemetery at East Challoch, which was then excavated and re-assembled.

A Romano-British copper alloy pin recovered from the Iron Age settlement at Myrtle Cottage was cleaned and stabilised. But the most significant artefacts to be recovered were 167 pieces of jet again from the Neolithic/Early Bronze cemetery at East Challoch, which appear to represent two necklaces. In the case of one of the burials, a matching bracelet was found. Additionally, the two separate graves each contained a ceramic vessel and a worked flint tool. The jet was conserved as a precaution to consolidate the material, to reduce the risk of further deterioration, and to facilitate preliminary analysis.
