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 pieces the justice that they truly deserves. This fascinatingly transparent piece of natural quartz is void of fractures and inclusions and was meticulously chosen during one of our many trips to South Africa.
The largest face of this crystal quartz is almost nine centimetres wide and for any rock or mineral enthusiast it's really exciting to be able to look right through a solid piece of quartz which has evolved over millions of years. After ice and the mineral 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 correctly known as rock crystal, varieties which are included or exhibit colour tend to either be known simply as quartz or have their own name. Some of the best known examples include rose quartz, smoky quartz, citrine, amethyst and rutilated quartz to name just a few.
