Complex pegmatite is usually more gem-bearing than the simple variety and a sure indicator of this is tinted quartz on the surface. Here it is tinted from \ buff to pink.

The aquamarine at Badmal ranges from blue to greenish blue, with the greenish blue turning a very good color after heat treatment. Badmal is difficult to mine as there is not enough water for the washing of the gravel. Ground water is found at a depth of fifty metres, which is too deep for the independent miners, so mining takes place only during monsoon season from July to October. Wholesale turquoise Jewellery
