An impressive chunk of polished quartz from our collection of crystals, rocks and minerals. Rock quartz as it's also known can be particularly challenging to photograph and sadly some of our photos don't do the individual piece the justice that it truly deserves. This transparent quartz mineral which is void of visible fractures and inclusions comes from South Africa.
The largest face of this chunk of crystal quartz is almost nine centimetres wide and it's amazing to be able to look right through a piece of rock which has evolved over millions of years. After ice and feldspar quartz is the most common mineral in the Earth's crust and it also has the largest number of gemstone varieties.
Only transparent, colourless varieties of quartz are known as rock crystal, varieties which exhibit colour tend to have their own unique name a few examples of which are rose quartz, smoky quartz, citrine and amethyst to name just a few.
