Mahogany Obsidian - Gemstone Gravel
 
Decorate your potted succulents by using gemstone gravel from of our decorative gravel range.
 
These shiny black and mahogany coloured stones are natural occurring volcanic glass. Obsidian forms from molten lava in the last stages of volcanic eruptions, the remaining silica minerals that flow onto the surface and are super-cooled into glass before crystallization can occur.
