About our Natural Rock Crystals (Size M,L)

Natural Quartz Crystals are also called Rock Crystals.

These days many crystals are grown or modified in laboratory or production environments. Our Natural Rock Crystals Crystals developed in nature by natural processes. As they are from nature they contain significant natural colour, shape and size variations. The crystal lengths fall into Size M & L. These crystals are doubly terminated meaning they have a pyramid shaped termination at both ends. 

We have divided these natural rock crystals up into three colour groups. Some colour variation will always exist within group.

  • Clear to Smoky Quartz
  • Reddish-brown Quartz
  • Yellowish-brown Quartz

Geodes, Geode Art and Crystals

By now we all know that a geode is a cavity in a stone that is lined with crystals or minerals. Quartz crystals are the normal crystals found in natural geodes so including them in geode art is a great idea. What better way to highlight the colours and beauty of crystals than to incase them in resin. They are also great for fish tanks. 

Geode Art is inspired by natural geodes. Geodes are characterised by crystals and over-the-top natural colours, sparkle and beauty …….. geode art should be too.

Some of the most common types of Quartz Crystals you probably know about are Clear Quartz, Smokey Quartz, Rose Quartz (pink), Amethyst (purple) and Citrine (yellow) but there are other less common colours including Blue Quartz, Prasiolite (green) and others. A great property of some of the quartz crystal types is their tendency to grow in a characteristic crystal shape (flat surfaces with distinct edges and one or both ends with a pyramid shaped termination). 

Crystals versus Stones

Think of crystals as very pure stones. But to avoid confusion we have used the following (non-scientific) classification in this website.

  • Crystals have a characteristic crystal shape with flat surfaces, distinct edges (or corners) and usually one or both ends have a pyramid shaped termination. 
  • Stones are random in shape and are not shaped like a crystal. Many pure stones are actually crystals but if they don't have a crystal shape we call them stones.  
  • Crystal Stones: we use this to describe crystal clusters that overall have a stone shape. The individual small crystals making up the clusters are visible.

If you have an interest in a little more beginners detail on the topic of crystals and stones you can download the attachment available on this webpage. This also discusses the quality, processing and value of gemstones such as sapphires, rubies and diamonds as well as the processing of stones by tumbling, polishing and cutting into gallets and cabochons...........and it's only 2 pages. Everybody buying jewellery should know these basics.
