Prehnite Tumbled Crystals
Prehnite tumbled stones a wonderfully subtle coloured crystal which made it particularly difficult to photograph them on a white background. Our third photo which features the stones on white oak is the most accurate representation of their colour.
The mineral prehnite was first discovered in the Cape of Good Hope by Dutchman Hendrik von Prehn after whom it was later named. Governor of the Cape of Good Hope and an avid mineral collector, Prehn is believed to have been the first person to have imported prehnite to Europe. It was named after him in 1788 three years after he died and is believed to be the first mineral to have been named after a person. Prehnite is also believed to be the first mineral to have been described from South Africa which at that time was not known for its rich mineral reserves.
Although brittle prehnite is a relatively hard stone that grades 6 to 6½ on Mohs scale of mineral hardness. It occurs in the veins and cavities of certain volcanic rocks and can be found in several countries around the world including the United Kingdom. Large quantities of gem grade prehnite come from the Northern Territories in Australia. Our prehnite tumbled stones come from Namibia.
Available in small and medium sizes, these prehnite tumbled stones come from Nambia in south west Africa. Weights and sizes do vary slightly from piece to piece. As with all of our tumbled stones they come in a colourful protective pouch.
