Emeralds discovered in the late 1940's and mined commercially in the 1950's and is now one of the worlds leading producers. 15 to 20% of the worlds Emeralds come from the Kafubu mine in Zambia
EmeraldColor: A really deep green.May's birthstone is an Emerald, which is found in many places in the world such as Austria, Swat, Zambia, Brazil, Pakistan, India, Zimbabwe, Madagascar, Afghanastan, Russia, Hiddenite, North Carolina, Yukon and more
Colombia probably produces the finest emeralds, for clarity, color, and size of faceted stone. Zambia and Brazil also produce vast amounts.
Almost all the African countries are famous for producing best quality gems. However, the top quality amethyst mines are located in Zambia. Brazil and Argentina in South America are the other places which have several amethyst mines, but the gem color is lighter.The other minor places where amethysts are mined include India, Canada, Madagascar, Mexico, Myanmar, Namibia, Sri Lanka and Tanzania.

The Copperbelt, a series of large deep mines and open cast mines stretches across northern Zambia.
Zambia is poor mainly due to mismanagement of the copper mines after they were 'nationalised' by Kaunda.
Zambia became poverty stricken when Kenneth Kaunda's government nationalised the copper mines soon after independence. The mines soon became inefficient and badly run. This was exaggerated by a world wide slump in copper prices from which Zambia has never recovered.

Yamfwa Mukanga is the Minister of Mines, Energy and Water and Chief Whip in Zambia.
Zambia has substantial deposits of several gemstones - including Amethyst, Aquamarine, Garnet and Emerald - but production has always been bedevilled by the unreliability of internal transport and reliable access to trade partners. i don't know which is Zambia's major gem export - but you could probably find that out for yourself by contacting the Ministry of Mines. (Zambians for the most part are some of the most polite and helpful people in Africa).
Zambia is poor in large part due to the government nationalising the copper mines and subsequently completely mis-managing them.
Zambia was starting to be industrialised in the late 1920's . By then copper mines had sprung up along the copperbelt, eventually resulting in 6 or more deep shaft mines. After WW2 the mines had really started producing a lot of copper. At this time 'open pit' miing also got bigger. The construction of Kariba Dam in the 1950's meant much more power available for industry.
some can be found in mines.... i thinkthey can also be found where there is wet land such as seas.
Colombia is considered to be the leading emerald producing country. The main mines of Colombia are located in Muso,Coscuez, and Chivor.
They can run out of ore, workers pay can exceed the value of what they mine or they can simply be mis-managed as the famous copper mines of Northern Rhodesia became when the country became Zambia and the government nationalised the mines.
