Diamonds grow like trees and often possess ’growth rings’ similar to those on tree trunks, new research has found.
Scientists also found that diamonds take millions of years to grow. They are often half as old as the Earth.
Diamonds consist of highly compressed carbon atoms and develop deep underground at relatively high pressures and temperatures of over 1000 degrees Celsius.
Earth scientists from VU University Amsterdam show that diamonds often have ’growth rings’ similar to trees: due to changes in temperature and composition, the chemical composition in the growth zones changes, which leads to the development of ’rings’ in the diamond.
