Coloured Diamonds Guide

Many Pragnell gemstones are considered best in class and are, therefore, incredibly rare. The scarcest of all gems on the earth are coloured diamonds.

“A coloured diamond is a touchstone of the universe, a little something God created that man can’t always find…they are the last frontier of collectable.”

Yellow Diamonds

Yellow Diamonds

Yellow diamonds are admired for their vibrant hues resulting from nitrogen atoms in their crystal structure that absorb blue light, reflecting yellow instead. They range in colour from pale yellow to rich canary yellow and are the most common coloured diamonds after white, making up 60 per cent of all fancy-coloured diamonds. Despite this, they remain rare, with only one in 16,500 carats classified as Fancy Vivid yellow.
