Well, I say 'beach', but it isn't quite the white sands/turquoise waters of some parts of Orkney, more a rocky foreshore with a bit of gravelly shingle.
And it is the shingle to which we are drawn.
Careful feet, keen eyes and enthusiastic hearts search amongst the gravel for the tiniest fragments of treasure. Not pirate contraband, you understand, but sea glass and other small nuggets of beach ware, originating from shipwrecks or coastal middens claimed by the sea.
Today's haul featured clear, green and blue glass fragments, as well as a piece of porcelain and a crab claw.
The large blue shard had some lettering on it, but all I could make out was an 'M'.
