Diamonds, like gold, silver and real estate are always in demand.
They also have an added bonus of being highly movable and durable assets. The fact that the global supply of diamonds is dwindling while the demand continues to increase makes them worthwhile. Despite the absence of a public trading platform, diamonds remain a highly liquid asset, and through globally recognised certifications, one can ensure the safety of their possession.
Over centuries, diamonds have been a favorite investment of the rich and powerful, sometimes for simply being easy to conceal and move around in times of crisis. The demand and supply of diamonds is heavily controlled and watched, thus maintaining and extending their value.
With diamonds, the 4Cs of cut, carat, clarity and color determines the quality and rarity, and thus, the value.
