Venezuela, Ivory Coast and continental drift The same diamond geological formations can be found in Venezuela as in the horn of Africa - yet another proof that the American and African continents were originally joined together. These two regions are the only ones in the world that produce very distinctive greenish-yellow diamonds with a very high fluorescence, which stands out in an extraordinary way under ultra-violet light. Rough, these stones usually have an octahedral or dodecahedral shape and contain few impurities. Among the color diamonds originating from these two countries, the intense yellow diamonds from Venezuela (many of which originate from areas close to the Brazilian border) deserve special mention. Types of diamonds produced in Venezuela: colorless, greenish-yellow, intense yellow, brown. Types of diamonds produced in Ivory Coast: colorless, greenish-yellow, brown.
