Put the diamond under the loupe or microscope and look for rounded edges that have tiny indented triangles. Cubic diamonds, on the other hand, will have parallelograms or rotated squares. A real raw diamond should also appear like it has a coat of vaseline over it. Cut diamonds will have sharp edges.

Human exposure to aluminium is inevitable and, perhaps, inestimable. Aluminium’s free metal cation, Alaq(3+), is highly biologically reactive and biologically available aluminium is non-essential and essentially toxic.
Is aluminium man made?
Aluminum was born out of science. Aluminum isn’t naturally found in the Earth’s crust. It comes from bauxite, which has to be processed to get aluminum. Essentially, innovation made this metal possible.As an interesting fact, Danish chemist Hans Christian Oersted first extracted aluminum from alum in 1825.
Is aluminium expensive?
Aluminium is the most abundant metal on Earth, but it is expensive, largely because of the amount of electricity used in the extraction process. Aluminium ore is called bauxite (Al 2O 3). The bauxite is purified to yield a white powder – aluminium oxide (also known as alumina) – from which aluminium can be extracted.
