Black Tigers Eye
Black Tigers Eye Tumbled Crystals
Highly polished black tigers eye healing crystals from the Northern Cape, South Africa. The colour of black tigers eye is produced by heating the brown and yellow coloured stone which changes the crystal's chemical makeup hence initiates a change in the stone's colour. Heat treatments are widely used around the world to enhance or change the colour of rocks and minerals and it's a practice that has been used for thousands of years.
Unlike the red variety of tigers eye which is also heated, black tigers eye retains its chatoyant properties and can often enhance them. Chatoyance is an optical phenomenon present in certain minerals that's caused as light reflects off the mineral's fibrous structure, inclusions or cavities within the stone. When a chatoyant stone is gently moved back and forth in good light, colours and markings seem to shimmer and shake but the quality of the chatoyance varies widely from one stone to the next.
The traditional brown and yellow coloured tigers eye is by far the best known variety and has long been used for lapidary purposes and in particular for gemstones. As well as South Africa, Australia and the USA also export large quantities of this popular variety of quartz and smaller quantities can also be found in several other countries around the world.
Black tigers eye is one of my favourite stones despite the fact that its colour has been produced artificially. With that said it's important to note that the process of heating rocks and minerals simply mimics the natural geological process which takes place over millions of years.
These fine grade black tigers eye healing crystals are wonderfully tactile and with shades and markings varying widely from piece to piece no two stones are the same. Ideal for use in crystal healing or to add to any collection of rocks and minerals.
Our black tigers eye crystals range in size from small to medium and as with all tumbled stones, weights and sizes do vary slightly from piece to piece.
