These three small blue agate /chalcedony crystals came from the Angus area. We recently purchased a half kilo of material from a fellow Scottish rock hound who covers that area and they sent us some gorgeous pieces. 
These three crystals are blue mossy with green and grey. The oblong one has red in it too. The halved nodule has dary grey blue bands with a central crystal pocket. These are lovely, elegant, shiny chalcedony crystals that we tumbled ourselves at home to finish.
