Diamonds

Diamonds are the crystallized form of carbon arranged in a tetrahedral structure. Exhaustible mineral originating in the Earth’s mantle over millions of years, diamonds collected on the surface are estimated to come from a depth of 150-225 km.
The production of diamonds is not fixed as mines are exhausted quickly and the size of production of new ones is unknown. It has been estimated that primary mines produce one carat (0.2 grams) of diamonds for every 3.5-4 tons of rock extracted, while alluvial deposits produce even every 15 tons.
Due to their chemical and physical characteristics, diamonds are used in jewellery and in the industry where both damaged diamonds and those not suitable for jewelery are exploited as well as synthetic diamonds, created with particular technological processes.
investment assets such as, for example, gold, more and more people decide to invest in diamonds.
