Pakistan Ruby - Hunza Valley

The Hunza valley is home to Pakistan's ruby deposits. After Burma, the only region in the world to produce ‘Blood Red’ ruby is Hunza valley. The Hunza is situated in the extreme northern part of Pakistan. The real 'Shangri-La', it is a stunningly beautiful valley, towered over by five snowcapped mountains. The ruby belt in Hunza Valley stretches over an area of about 100 kilometers.
Ruby is a rare gem because the chromium pigments embedded in the earth’s crust are not plentiful and the chromium had to meet up with the element alumina at the exact moment that crystallization occurred. Without these two elemental factors the gem won't be red. The ruby deposits occur in metamorphosed re-crystallized limestone marble in a narrow belt from Hunza Valley to Ishkoman.
