DIAMONDS
The Diamond. An everlasting stone.
UNIQUE. PRECIOUS. EXCLUSIVE.
The use of a diamond
Not all diamonds can be considered stones for investment, as not all stones have the right requirements to be in this category. There are three sectors for diamonds:
- Diamonds for industrial use (80% of the market) = = rough and very poor diamonds used for specific productive process.
- Diamonds for commercial use (20% of the market) = diamonds of quite good quality used exclusively for the jewelry market.
- Investment Diamonds (1.5% of the commercial market) = Diamonds of excellent quality, in this category there are only the best stones that will increase their value over time.
Rarity
What does the value of a diamond depend on? On rarity and on a series of characteristics or evaluation parameters that give to it a precise value. The classification of 4 Cs (or the International System of Classification) was introduced by G.I.A. (Gemological Institute of America) and solved a problem that had afflicted the world of diamonds.
Quality
A brilliant cut diamond of 1 carat presents more than 4000 different qualities with different values depending on its purity, colour and cut. The diamonds considered to be unique and exclusive are only one in a hundred.
The Strongest One
The diamond is a natural mineral of crystalline formation of pure carbon. It is the toughest mineral and it is classified at n. 10 on MOHS’s scale.
MOHS’S SCALE
In 1812, Friedrich Mohs elaborated his famous Mohs’s Scale, which represents a method to evaluate mineral strenght. Primarily it is an empirical criterion that uses the strenght of ten minerals from the softest to the hardest one: talc, gypsum, calcite, fluorite, apatite, orthoclase, quartz, topaz, corundum and diamond.
These minerals are disposed in order that the harder material is able to scratch the softer one. The softer mineral is the talc that can be scratched by a simple nail and the hardest is the diamond that has no rivals.
