The pebbles found at Therma beach here in Ikaria, are a stone collectors dream! The small bay collects and holds these wonderful little gems, so that they can be found when beach combing.
The colours and textures are something to behold, and the variety of stones found I have not seen anywhere else. Quartz, banded agates, granite, jasper, and many more are found here.
The stones come from the sea of course, and also they get washed down from the mountain range on the island, if you go and look at the cliff faces near the beach you can see these very stones jutting out from the mud and rock; fascinating!
