‘What do Sierra Leone, Liberia and Guinea have in common?
Strangely enough more than just Ebola. Western Liberia is part of an Archaean age craton which spreads into Sierra Leone and Guinea. This type of rock strata is full of diamondiferous kimberlites.
What makes the diamonds of Sierra Leone, Guinea and Liberia so special is that this is one of the rare regions in the world containing large alluvial diamonds, ie. whopping huge rocks of 300 plus carats.’
