Lab grown coloured diamonds are graded by the same 4Cs as regular diamonds: Carat, Cut, Clarity, and Colour.
The only difference is that the colour grading for fancy diamonds is not the same as colourless or white diamonds — they are measured on a scale ranging from Faint, Very Light, Light, Fancy Light and Fancy to Fancy Intense, Fancy Vivid, Fancy Dark and Fancy Deep. Lab grown coloured diamonds with colour gradings of Fancy Intense and Fancy Vivid have the most colour and are highly valued.
Just like natural fancy-coloured diamonds, the lab grown family-coloured diamonds come in twelve pure hues including blue, pink, yellow, orange, green, brown, grey, purple, violet, red, white, black.
Though they may look similar to their gem counterparts, naturally coloured diamonds are much rarer due to the number of elements that need to be present for their creation deep in the earth. Each coloured diamond is placed in a certain range of colours that determines its value.
Yellow-coloured diamonds are one of the most popular variants, forming in the presence of nitrogen. Because of their bright lustre, they are best used as centrepieces in jewellery, such as the main gem of a necklace. Yellow diamonds are often a symbol of happiness, friendship, and hope.
Blue diamonds are highly prized for their exceptional rarity and brilliant appearance. Formed in the presence of boron, diamonds with a blue hue make for an ideal choice in engagement rings or wedding rings due to their symbolic relationship with eternity, devotion, and truth.
Orange diamonds are sometimes referred to as “pumpkin diamonds” due to their rich and bright shine. They are generally considered one of the rarer types of coloured diamonds. Orange diamonds typically represent energy and zest.
Brown diamonds are among the more common types of colour diamonds, accounting for almost 15% of naturally mined diamonds. Despite their common nature, this more mellow shade of diamond has become increasingly popular in Australia becasue of its versatility in matching almost any type of skin tone, earning it the moniker of “chocolate diamond”.
