This is a question with no possible correct or accurate answer.
Since diamonds have been 'known' since about 6,000 BC (in India), and with diamond mines all over the world, a even an estimate by soil tonnage might be difficult, considering that tonnage produces a limited gross weight in diamonds (i.e.,12,000 carats from more than 240,000 tonnes in the Argyle Mine, the largest being ~46 carats).

Statistically, given that some diamonds have been mined from the earth, and some have not, it is not possible to determine a number, since we cannot know how many diamonds remain un-mined.
There are numerous 'kinds' of diamonds -- too many to list. The number of diamonds cannot be determined, since not all diamonds have been mined to date.
Mined diamonds are as old as Mother Earth herself.
This is a question with no correct or accurate answer. Humans have been picking up diamonds since 6,000 BC (in India), and raw diamonds can be cut into many pieces, depending on the original size of the raw stone. In addition to all the mined and found stones accounted for, there are stones without record. Diamonds are also mined by criminal enterprises, where records may not be kept. Finally, cut and polished stones can be re-cut and in some records become new and additional stones. You can read more about diamonds by following the link, below.
It is not possible to answer this question with a precise number, because diamonds are being mined daily, lost daily, and formed daily.

Yes, diamonds are mined.
The earth is mined to get diamonds.
Gold and diamonds are both mined in the earth.
Diamonds mined in Australia follow the same type of distribution channel as diamonds mined in any country. Mined diamonds are graded, brokered, then bought and sold based on the diamond's quality.
Because the diamond mines have not been exhausted, it is not possible to predict how many more remain to be mined.
mined (like mined for diamonds)
Yes, diamonds are mined in South Africa.
On average, around 100 million carats of gem-quality diamonds are mined each year, which is roughly 20 tons. This accounts for roughly 1% of the total diamonds mined annually.
Brown diamonds are the most common colour of diamonds mined, of gem-quality. Only about 20% of all diamonds mined are of gem quality.
This question is impossible to answer, since diamonds are mined from the earth. The diamonds in South Africa -- or anywhere -- can't be counted until they are brought to the surface and counted.
