Advice from the Diamond Expert
Choosing a diamond colour is an important decision, so it is essential to be discerning. On the GIA colour scale, diamonds are graded from D (colourless) to Z (light yellow or brown). The closer the grade is to D, the more colourless—and generally more valuable—the diamond will be, assuming the other quality criteria are equal.
However, naturally coloured diamonds follow a separate grading system. Their value depends on the rarity of their colour, its intensity and its distribution throughout the stone. While some diamonds with noticeable yellow or brown tones may be more affordable than colourless diamonds, rare Fancy-colour diamonds can command considerably higher prices.
The best way to choose a diamond colour is to view the stone in person. Ask your jeweller to show you several diamonds with different grades and hues so that you can compare them under the same lighting conditions. Remember to select a wedding ring that pairs harmoniously with your solitaire engagement ring, your bridal jewellery and any chosen gemstones. If the diamond is certified, carefully check its grading report before making your decision.
Congratulations—you now understand the symbolism behind diamond colours. You can also create your bespoke wedding ring for a completely personalised piece.
