Fluorite is a soft and brittle mineral that can occur in wide range of colours, ranging from bright green, blue, pink and purple to much paler shades of these colours to virtually colourless. Its hardness is 4 on Mohs' hardness scale and it has 4 directions of perfect cleavage, which makes fluorite unsuitable for most jewellery.
The Madoc area produced fluorite for industrial purposes between 1905 and 1961. Mineral collectors have occasionally unearthed fine mineral specimens since then. There are dozens of sites in the Madoc area where fluorite was either produced or known to occur. The gemstones offered for sale on this page have been cut from fluorite collected in the Madoc area.
