Claddagh ring blog - The rarest diamonds
To date we have never been asked to make a Red diamond claddagh ring. Red diamonds are so rare that only around twenty to thirty true red diamonds are known to exist. Most of these red diamonds are less than half a caret size.
Unlike other fancy colour diamonds, red diamonds are made purely from carbon. The red colour is created by a rare deformation in its atomic structure. known also as 'plastic deformation.'
Red diamonds look different in various lighting conditions and surroundings. They look their most excellent in daylight and candlelight and they appear of poor quality in fluorescent light. Natural red diamonds are graded by the great intensity of their colour. They range from dark pink to purplish red. The stronger the colour, the greater the value of the diamond.

THE KAZANIJAN RED DIAMOND:
One of only three red diamonds over five carats. It is an emerald-cut stone. It has a dark hue resembling that of a garnet or a ruby, and in its nearly century-long history, it has been mistaken for the latter. It has a colorful history. In 1944, the Nazis occupied the Netherlands and confiscated all valuables, including this diamond.
