Whilst the best white diamonds are completely colourless, there is a grade in Fancy Colour Diamonds known as a Natural Fancy White. When I look at certain paintings I am reminded of this paradox..... Artists all have different ways of using white paint to convey both form and light.
I find the impact of seeing colour in unexpected places such as these houses is especially thrilling. It's the same thrill I get when I discover a new brilliantly coloured diamond. And the same reaction I see when showing coloured diamonds to clients who are expecting them to be white.
