This large quartz crystal is a real chonker. We have had this for so long that we can't put an exact date on it. Katriona started hunting for rocks around 2017 and this quartz crystal from Scotland precedes the Stone Circle itself, which didn't begin until 2020... So it's been on the surface for some time now.
Why not sell it sooner? This is a heavy piece. We reckon there is barite in it somewhere. We wouldn't recommend this for cutting or grinding. It was found down in Dumfries and Galloway from one of our favourite spots near the Southern Uplands Way. 
The quartz crystals are iron stained but well and truly coated. The crystal range from clear, to yellow, to deep orange.
