A Solution in
turbulent times

Grosvenor Diamonds is an independent investment diamond brokerage specialising in rare coloured diamonds.

Unlike most investments, diamonds have proven to be resilient during times of political and economic instability.  Pre-approved clients have the very highest levels of protection as Grosvenor Diamonds only source natural diamonds which have been certified by globally recognised gemmological laboratories.
