World-wide convertibility, meaning that diamonds are – together with gold – the only international accepted alternative currency which keeps the same value all over the world

Not to forget: diamonds carry unequalled emotional values lasting multiple generations Theoretically a (world) war could devalue any currency, real estate can lose its value, new technologies can replace resources, competition can ruin companies, but nothing can systematically undermine the long term value of diamonds. While most diamond mines are nowadays known, with time diamonds will become even more rare, just as any natural resource will. This fact carries the key boosting effect on the long term value of diamonds

Diamonds are – together with quality artworks – one of the very few goods that combine its practical use with its investment aspect. Meaning: while you can wear your diamonds set into/as jewellery, simultaneously they symbolise your most secure investments.

Finally, while most of the other luxurious goods, such as cars, furniture, furs, etc lose their value over time, this is not the case with diamonds, precisely because of its durable/unbreakable nature.
