0 Is this guide helpful? 2 0 Report
 

Stichtite is a mineral, a carbonate of chromium and magnesium. Its colour ranges from pink through lilac to a rich purple colour. It is formed as an alteration product from chronium containing serpentine. Discovered in 1910 in Tasmania, Australia it is named after Robert Carl Stitch the manager of the nearby mine.

The hardness in generally 1-2 on the Moh's scale and is a pretty rare stone.

Value is placed on :

  1. Colour of the serpentine - the darker green is more priced by lapidary circles due to te ease to work with
  2. Amount of stichtite - though the more you have, the harder to work with the rock
  3. Dendrites - mixed feelings within the lapidary circles and can be seen either as a feature or a flaw
Polishing and handling
  1. You only need to polish to 600 grit
  2. Then use the back of your jeans and begin to rub
  3. Generally better for jewellery on the upper part of your body rather than rings as it can be fragile.
I also have this available by the kg. Let me know if you prefer this option. Whole stones can be somewhat better to worked on as you are the cutter and not relying on someone else to cut for you.
