Proper mining techniques and skilled labors are what we need now in our gemstone mines. People are simply using chisel and hammer for breaking the rock masses which contain gem crystals. Not all gems have greater hardness than hammer (iron). Even some people are using explosive for blasting the rocks. This may cause severe damage to the crystals.
This crystal is from Barala vdc, Achham where I went for the exploration of one deposit. The cracks seen in this cystal are due to hammering.
Can anyone guess what gemstone crystal is this?
