Mugglestone (also known as Tiger Iron) is a hugely energetic healing crystal and is a strong grounding stone. Like TigerJasper, this stone is a combination of Red Jasper, Hematite and Tigers Eye, however this stone is notably heavier and has more of a reddish hue than the Tiger Jasper. 
This stone will give you courage, strength and stamina and help you see things through to the end
