PAKISTAN Tourmaline from Estaknala, located atrepparttar foot of Haramosh mount, 7 kms from Sassi. (Between Gilgit and Skardu) The Northern areas conceals treasures, such of rubies, emeralds, sapphires, aquamarines, topazes, tourmalines etc. Unfortunately, their extraction directly inrepparttar 109298 mother-rock, makesrepparttar 109299 exploitation very difficult. Emeralds from Sassi found in a limestone.

A gravel-top 241 kms road track connects Gilgit to Skardu,repparttar 109300 capital of Baltistan perched 2438 meters above sea level. The journey takes 6 to 8 hours. Sassi is located atrepparttar 109301 edge of this road, inrepparttar 109302 geological belt made up amongst other things of amphibolites surrounding Nanga Parbat, one ofrepparttar 109303 famous peaks ofrepparttar 109304 Himalayas.

A day of July 1996 whereas I stopped in a small village in Madagascar, one presented samples of a strange stone to me. At first sight its color could reminds certain zircon, but I quickly identified them as garnet. After some palaver, one led me torepparttar place ofrepparttar 109297 discovery. I must acknowledge that I already knewrepparttar 109298 inhabitants with whom I tied friendshiprepparttar 109299 previous year. Onrepparttar 109300 spot, a notch of about one meter fifty in a white color rock had created a not very impressive hole. But, according to its authors, it was particularly painful to produce it with iron bars only . I readily believed them after to be approached torepparttar 109301 rock. Some particles of this stone torepparttar 109302 orange - pink-brown reflections remained taken inrepparttar 109303 bedrock. I encouraged my friends to be still sought. The first samples extracted from a not disaggregated leptynite did not exceed 3.15 cts. after cutting. The observation under day light and incandescent light showed a clear difference in color. Its change, fromrepparttar 109304 champagne color under daylight, to an intense red for some, or to pink-orange for others is due to chromium and vanadium traces. This characteristic confers an attractive aspect on these gems. Other samples were orange-yellow and did not change a color underrepparttar 109305 various sources of lighting. Unfortunately,repparttar 109306 very hard and compact rock in this place, did not allow to extract many stones from it, andrepparttar 109307 occurrence was abandoned a few weeks after its discovery.

Opposite, first samples cut in 1996 showing a change of color. Above, an orange malaya found also inrepparttar 109308 primary occurrence. (It does not change a color) This is two years later, exactly in September 1998, that returning inrepparttar 109309 small village,repparttar 109310 samples more or less similar to those which I make cut in 1996 were found. They were turbid because ofrepparttar 109311 fine rain of small bubbles they contained. Their color was definitely more orange than malaya garnets fromrepparttar 109312 first occurrence. Indeed, they did not come fromrepparttar 109313 same place. This is a little more than one kilometer of distance thatrepparttar 109314 elluvionnar deposit was discovered. I was immediately conscious to berepparttar 109315 witness of a rare moment inrepparttar 109316 career of an impassioned person in precious stones.
