Shazar in Persian means tree,and the stone,dendrite agate,
gets its name from beautiful formations in the stone.
There is a natural process behind the formation of images within a Shazar stone.
The patterns we see in the shazar are entrapped fossils of fungus ( basically, algae).
When entrapped between two or more pieces of shazar stone,
the fungus produces either an acid or base secretion,
which makes the stone translucent and acts as an inorganic glue that fuses
the separate stones into one.
The fungus fossil inside the stone looks like patterns of leaves or trees and adds to its beauty.
The exquisite patterns of black and orange in the store are actually deposits of iron and manganese that have entered the agate under high pressure.
The stone has to be sliced carefully to reveal them.
The craftsmen look for a gaanth,knot,on the surface.
The deposits are not evenly distributed and all stones do not have a clear dendrite formation.
It takes experience to find out in which layer the deposits are likely to be.
The stone is sliced using a huge bow-saw or power lathes.
The fine slices are polished on a grinding wheel and buffed.
They are then set in gold or silver by the jewellers.
Because of its uniqueness, the stone was exported to foreign countries until last few decades. But due to cold eye behavior of Govt., its export has been declined to a nose-hit level.
In fact, still there exists a small industry of Shazar stones to cater
demand of local and national market.
The stone is still popular in middle-east and this ensures cent percent success of export program if resumed again.
I love discovering new kind of jewellery and my next target is this
Shazar stone jewellery.
Do let me know, if you have some more information.
Last but not the least, a beautiful quote I came across
“The creation of the world did not take place once and for all time, but takes place every day.”
