What is the specific gravity of sapphire?

Answer 1

"If you have ever watched one of the older Superman films, you may have seem the famous clip where Superman turns a chunk of coal into a diamond. This is impossible.

The density of coal is 1,330kg/m^3 whereas for diamond it is 3,520,000,000 kg/m^3. When diamond is divided by coal, we learn that diamond is 2,646,616.5414 times more dense than coal. If Superman really was to turn coal into that perfect diamond he would need 9316kg of coal, that is about four or five SUVs. That would be cool."

.... Ah.. no.

The density of diamond is typically around 3,500 kg/m3, and thus has a relative density of 3.5 i.e. a density 3.5 times that of water.

If the density was 3,520,000,000 (!) as stated above, a ladies wedding ring, with a volume of 1cm^3 (big rock!) would weigh (i.e. have a mass of) 3,520 kg!! That's over 3 tonnes.

Not even a Bavarian Barmaid could handle such a ring!

Superman could achieve his feet, though his diamond would be one third the volume of the coal he started with.

Answer 2

== == The specific gravity of gold is 19.3 (times the weight of water).

Answer 3

The specific gravity of a diamond is 3.52.

Answer 4

The specific gravity of pure diamond is 3.52 g/cm3.

Answer 5

Diamonds do not always have the same weight; they come in many different sizes.
