![Silver Geode Mini Pin](http://www.pinandtonic.co.uk/cdn/shop/products/BlueGeode_{width}x.png?v=1591785255)
Geodes are formed over thousands of years when water seeps into hollow, pourous rocks! Pressure, time and a little magic later and they form beautiful displays of colour and crystals.
This slice will fill those gaps between larger pins perfectly!
