We picked up this larvikite back in October in 2023. We found it down in Dumfries and Galloway where there are thousands of different minerals - but not larvikite!
So why was it in Scotland?
The material was brought over from its native land to the shores of Britain. Once in Britain, larvikite was used to build naval defenses offshore. This means that once in a while we find it washed up, rivers and waterways, uneven crushed up and used as pathway material out in the wilderness, which is how they discarded the excess.
So one day we were climbing a hill in the rain and we saw all this sparkling, beautiful larvikite shining blue flashes at us. We picked it up, we brought it home, we washed it, and then we put it in the rock drawer and forgot about it.
We did try to tumble this before and we couldn't get a good shine on it. We have now achieved a good shine with these pieces but it looks like they have lost some of their blue flash in the tumbling process. 
Larvikite is known as the poor man's labradorite, and when you look at the video of these pieces you can see why. They are almost moonstone. They are almost labradorite. However, they are also lovely in their own right.
Larvikite comes from Larvik in Norway originally. It is often referred to as blue pearl granite when polished. 
We might just list the other pieces without polishing them for better flash. Keep an eye on the Stone Circle website and Etsy pages for more.
