Brazil
Diamond Characteristics
Minas Gerais diamonds were relatively small (7 to 8 carats), of a very beautiful quality and color blue-white, yellow and red. Mato Grosso produces diamonds of a worse quality than Minas Gerais, crystalshave an irregular shape, generally elongated and their color is very often tinted (yellow, green, red, brown). Mato Grosso produces a category of diamond called "carbonado" which would be even harder than diamond and which is very much used by cutters.

Localization of Diamondiferous Areas
Diamantiferous deposits are localised in the areas of Minas Gerais and Mato Grosso. Minas Gerais is composed of alluvial deposits. It is in this area that there is Diamantina which produced more than 100,000 carats of diamonds per annum. A little morethan 30 % of diamonds are gem quality.

Localization of Diamondiferous Areas
Diamantiferous areas are located in Northwest Territories, but also in Alberta, British Colombia, Labrador, Manitoba, Ontario, Saskatchewan and Quebec. There would be 500 companies which prospect and explore these vast territories. Northwest Territories seems to be a privileged target. Nearly 200 kimberlitic pipes were identified in Northwest Territories.

Localization of Diamondiferous Areas
Diamonds deposits are concentrated in Kasaï-oriental, near Mbuji-Mayi, and in the Kasaï-occidental. Whereas in this area, they are alluvial, in Kasaï-oriental, the deposits are at the same time alluvial, eluvial and primary and closely related to underground kimberlite chimneys. Diamonds are found in Low-Congo, High-Congo, Maniema, Ecuador and Bandundu. It is very often necessary to remove a great quantity of sterile before reaching the diamantiferous gravels (deposits of Mbuji Mayi). Approximately 85% of the production have an industrial quality.

Mining Code
The principal law is the law of the mines and the minerals which was adopted in 1986 (Law PNDC 153). It regulatesmining industry. Exclusive mineral rights are allotted by the Ministry of Mines and Energy, namely:
- Reconnaissance
- Prospection
- Mining Permits The government takes a free participation of 10% in the capital of the mining companies. The royalties vary from 3% to 12% of the amount of produced minerals.

Localization of Diamondiferous Areas
Diamantiferous deposits are located mainly in the Banankoro-Sefadou area in the South-east of Guinea. It extends since the border from the Sierra-Leone in the West to the Simandou mountain range. This area has rich in Kimberlites and diamantiferous placers. One could define this zone by a quadrilateral delimited by the towns of Kérouané-Macenta-Gueckedou-Kouroussa, as well as Kimberlite deposits towards Forecariah. Approximately 75% of diamonds are gem quality. The diamond reserves rise to 25 million carats (2/3 are gem quality).

Liberia
Diamond Characteristics
The quality of diamonds is not very good, crystals are for the majority octahedral. Approximately 60% of diamonds have industrial quality.
Quality of Diamonds
Localization of Diamondiferous Areas
Liberia has a good potential but it remains underdeveloped today. Kimberlites (in the West) were identified and evaluated, the results of these studies show that it would not be profitable. Alluvial exploitation is practised in the rivers of Lofo and Mano near the border of Sierra Leone. Alluvial deposits are known also in the districts of Montserrado, Nimba and Large Bassa. Diamond traces exist in addition near the Greenville coast and we can think that there is a potential of marine deposits for this country.

Mining Code
Modern mining laws are not yet in place. The current Mining Code goes back to 1956. The diamonds law, of 1958, was revised in 1979 to include the exploitation of gold and to allow the foreign participation in the exploitation of the alluvial deposits.

Diamond Characteristics
The quality of diamonds is very good. Russia produces very beautiful octahedral crystals from 40 to 100 carats.

Localization of Diamondiferous Areas
Russia is a large diamond producer. There are diamantiferous deposits in Siberiaand in the north of the town of Perm. Zones very rich in diamonds are in Yakutia in the Republic of Sakha. The exploitation is a problem in this country because of the winter temperature which varies between -30 and -60 degrees. The ground can remain cold until depths of 400 meters.

Diamond Characteristics
The quality of diamonds is good, crystals are rather large, they are generally of a good clarity and color. The largest rough diamond found in 1972 weighed 970 carats, it is called the Star of Sierra Leone.
Quality of Diamonds
Localization of Diamondiferous Areas
Diamantiferous deposits are located towards the guinean and liberian borders and along the Sewa river. These deposits are alluvial, and it is very often artisanal exploitation. There are also pipes kimberlites in the areas of Yengema and Tongo. Evaluation of these pipes is carried out by a Canadian company. Revolutionary United Front (RUF) disturbed the diamantiferous exploitation since 1992. The explorationof diamantiferous sites offshore is in progress.

Diamond Characteristics
Diamonds are often small. Nearly 70% of diamonds are gem quality. The diamond mine of Mwadui produces fancy color diamonds, in particular pink and green color of a very good quality.
Quality of Diamonds
Localization of Diamondiferous Areas
More than 300 kimberlites were identified in this country and 44 of them are diamantiferous. The zones of diamond exploitation are located near the Lake Victoria at Mwadui in the North of the country. The kimberlitic intrusions are relatively young in this country and, by consequence, they have not undergone an intense erosion, which explains why there is mainly this type of deposit.
