Dumortierite Gemstone Pendant
Dumortierite which is a lesser known gemstone variety is sometimes mistaken for sodalite or lapis lazuli because of its navy blue colour. Found in metamorphic rocks rich in aluminium, the finest grade material can be quite beautiful and often features a mass of long slender crystals which occur deep within the mineral quartz. The crystals have a vitreous lustre, tend to be quite small and may exhibit pleocroism with shades of colour varying from red to blue to violet. Commercial grade dumortierite are used for lapidary purposes and thye're actually quartz that's heavily included with dumortierite.
A surprisingly light weight stone dumortierite grades 8 on Mohs scale of mineral hardness which is fairly hard which makes it quite easy to work with.
This highly polished cabochon has been mounted as a ladies pendant in a hand crafted sterling silver setting. In our second photo the setting looks deeper than it actually is due to the angle at which the photo was taken. It is in fact the same as almost all of the other gemstone pendants in our collection.
