Diamond is one of the natural allotropes of carbon. Diamond is the strongest known material. It has the highest thermal conductivity, 2000 W/m·K. It is very resistant to chemical corrosion. Diamonds have high electrical resistivity. Resistivity is a measure of how strongly a material opposes the flow of electric current. It can be expressed as …

ρ = RA/l

Where

ρ = resistivity

R = resistance

A = cross sectional area

l = length

The units for resistivity is ohm·meters (Ω·m).It is temperature dependent.At room temperature, diamond is a good insulator with a resistivity of 1 × 1018 Ω·m. There are four diamond types: type Ia, Ib, IIa, and IIb.Type Ia, Ib, and IIa usually have a resistivity of 1 × 1018 Ω·m.Type IIb has a resistivity of 1-105 Ω·m.They are natural diamonds, but Type IIa is the purest one.
