With an international approach to design and gem sourcing, Simson Bespoke brings the best of the world to each creation, along with a commitment to supreme craftsmanship and personal service. Simson Bespoke specialises in fancy coloured diamonds – in particular investment diamonds. These revered stones form an asset class that is tradable, collectable, and easily transferred; and they traditionally maintain value in times of adversity. The performance of coloured diamonds as a whole has seen annual price increases of 10% to 35% (depending on colour) since 2002.
