Rubies in Mozambique. The Montepuez ruby mine in the north-east of Mozambique boasts the largest ruby asset globally and is currently valued at around $1bn. It produces some of the oldest rubies in the world, originally formed 500 million years ago. Comparatively, Burmese rubies, some of the most popular on the market, are a mere 25 million years old. Rubies are the most highly valued ...

For the purpose of Paraíba tourmaline origin determination, if the LA-ICP-MS analyses identify a cuprian tourmaline as liddicoatite, the stone’s origin is conclusively Mozambique. Copper-bearing tourmalines are reported to occur in various colors, including pink, purple, violet, blue, and green (e.g., Laurs et al., 2008).

A land mine is an explosive device concealed under or on the ground and designed to destroy or disable enemy targets, ranging from combatants to vehicles and tanks, as they pass over or near it. Such a device is typically detonated automatically by way of pressure when a target steps on it or drives over it, although other detonation mechanisms are also sometimes used.

By this time, it was reported that there was very little activity and the locals thought the deposit was mined out (Nguni and Mwamba, 2004). No in-situ emeralds were found, but small emerald fragments were recovered from eluvial lateritic soil adjacent to quartz veins at two mines (Hope and Musakashi) in the Chief Mujimanzovu village area.

The tourmaline has been mined since 1983 from both pegmatite and eluvial/alluvial deposits, in colors typically ranging from yellow-green to yellow to orange and brown; much of the orange-to-brown material is heated to attain a golden or canary yellow color. The tourmaline is Mn-rich (up to 9.18 wt.% MnO documented in the literature) and contains traces of Ti and little or no Fe. The distinctive composition of this tourmaline is probably the

Nowadays, all of its known deposits are mined out, so it’s almost impossible to buy it on the market. Its price is really high, around 4,000 USD per carat. As you can see, elbaites are the most variable group of tourmalines. They are also in the hands of gemcutters most often and are most often used in jewelry-making. DRAVITES

The south end of the quarry had been mined to a lower level, but the north end, over an area of perhaps two acres, had been mined down to the top of the best geode zone. It was probably a natural, shaley break in the quality of the limestone and a logical place for the floor of a bench. The rocks there have a very shallow dip and while the south end of the pit was deeply flooded the north end was dry and the rock surface sloped gently into the advancing water.
