How was Earth shaped?

So, the answer to our question is ... yeap, you guessed right ... diamonds!

How the Planet functioned more than 3.5 billion years back?

The three diamonds, which were drawn out from the 3 billion-year-old Witwatersrand Supergroup-- the rock development that is host to the well-known Johannesburg golden goose-- were investigated by Wits University, the College of Johannesburg, and also from the University of Alberta (Edmonton, Canada).
They examine when modern-style plate tectonics started to operate on Earth. The diamonds were generously provided by Museum Africa, situated in Johannesburg, with the assistance of curator Katherine James
The eco-friendly Witwatersrand diamonds were discovered in the Witwatersrand empire, where the gold was found that caused the facility of the city of Johannesburg.

A bit of history

A number of these diamonds were located between 1890 and 1930 when men were still mining manually. After the industrialisation of the mines in the 1930s, most of the diamonds in the corporation were squashed to dirt. Therefore, the Witwatersrand diamonds are exceptionally unusual.

The Witwatersrand corporation is known to be at the very least 3 billion years old. The diamonds that are discovered in the empire are referred to as "placer" diamonds. 
These diamonds did not come from the conglomerate but were delivered from their original kimberlite resources by additional means, such as rivers.

A lot of diamonds are believed to be younger than three billion years of ages, yet as the Witwatersrand conglomerate is understood to be three billion years of ages, the diamonds found in the corporation should have been developed greater than 3 billion years ago. Thus, they could be referred to as "confirmed old diamonds".

Diamonds collected from old rock formations in the Johannesburg area, in between 1890 and 1930 have disclosed tricks.

"Since rubies are several of the hardest, most durable material in the world, they are perfect little time pills and have the ability to tell us just what procedures were taking place very early in Earth's history".
