One day we will manage to find a set of three matching blue diamonds to make an all-diamond 3-stone ring...
It is much more difficult to find sets of three matching blue diamonds, than to find three matching white ones. We will manage it one day, but until then, we believe that a centre blue diamond with a pair of white diamonds at the sides makes a refreshing and vibrant change from an "ordinary" diamond 3-stone ring.
Three Stones
Fancy coloured diamonds are very effective when used in conjunction with white diamonds. A blue centre diamond with two near-colourless ones retains a traditional look. The owner could retain the secret that the centre stone was a diamond while an onlooker might assume wrongly that it was "only" a sapphire.
