Not all diamonds are equally hard, remember Mohs scale is only that - a scale. Depending on the perfection of the crystal, diamonds may be harder or softer - but are all considered 10 on Mohs scale.

Then, those that are coloured, flawless and large become the multi-million dollar objects you read about in the news.


Diamonds are more costly than glass because they are purer?

The difference between Diamond and Glass is that, Glass is softer than the diamond. A diamond can easily scratch the glass. Glass is an inorganic product of fusion which has been cooled through the glass transition to a rigid condition without crystallizing. The reason why diamonds are more expensive is : Actually, diamond has many unequaled qualities. It is the hardest known substance, it is the greatest conductor of heat, it has the highest melting point of any substance (7362° F - 4090° C), and has the highest refractive index of any natural mineral. Diamond is number 10 on the Mohs scale, and is 40 times harder than Corundum, which is number 9 on the Moh's scale (and the next hardest natural substance). It also has the most dense atomical configuration of any minerals, and is transparent over the greatest number of wavelengths. Because of heat conduction, Diamonds are cold to the feel at or below room temperature. When heated, a Diamond will remain hot long after the heat source is removed. The luster of Diamonds is excellent. Diamond exhibits great "fire", or brilliance, which gives it a shiny, freshly polished look. Rough Diamonds exhibit a greasy luster, but proper cutting give them a powerful adamantine luster. Only synthetic substances and a few minor gemstones can reach or excel the refractive index of Diamonds.


What are the uses of formula hardness specific gravity transparency etc of diamond?

Diamonds are most useful in industrial applications, usually based on the mineral's supreme hardness. Transparency is one of the characteristics of gem-quality diamonds, which represent only 20% of all diamonds mined. From Wikipedia: "Specific gravity is the ratio of the density of a substance compared to the density (mass of the same unit volume) of a reference substance." You can read more about the specific gravity of gemstones, below. It explains how specific gravity is used to identify gemstones.


Can diamonds be lustrous?

From the Minerals site, below: "The luster of Diamond is excellent. Diamond exhibits great fire and brilliance, which gives it a shiny, freshly polished look. Rough Diamonds exhibit a greasy luster, but proper cutting give them a powerful adamantine luster.
