The short answer: lab grown fancy colour diamonds come in pink, blue, yellow and other colours, and they let you have a vivid coloured diamond at a more accessible level than natural fancy colours, which are very rare. Check the report for how the colour was created.
Natural fancy colour diamonds are exceptionally rare and valued accordingly. Lab grown versions make colour available to many more people, and they are a wonderful basis for an individual, bespoke ring.
The colours
| Colour | Typical look |
|---|---|
| Pink | From soft blush to rich pink, romantic and warm. |
| Blue | From pale sky to deep blue, cool and striking. |
| Yellow | From light lemon to deep canary, bright and cheerful. |
Other colours such as green and orange also exist, depending on the stone.
Colour intensity
Reports grade the strength of colour, from faint to vivid. A more intense colour tends to be more striking, and a paler colour is subtler. We can show you stones on video so you can see the real colour in different light, because colour can look different on a screen, in daylight and under shop lighting.
How the colour is made
Fancy colours can come from the way the diamond is grown or from treatment afterwards. The report should say which. We explain what each means, and we make sure you know what you are buying. See colour treated lab grown diamonds explained.
Primary and secondary colours
Many coloured diamonds show a main colour with a hint of another, described on a report with words such as purplish pink or greenish blue. The secondary tone changes the mood of the stone: a purplish pink feels cooler and richer, while an orangey pink feels warmer. Neither is better, so look at a few stones side by side and choose the one that speaks to you.
Settings for fancy colours
- Halo of white diamonds: makes the colour pop.
- Solitaire: a clean look that shows the colour fully.
- Rose gold or yellow gold: warms pinks and yellows.
- White gold or platinum: keeps blues cool.
Shape and colour
Cut affects how colour appears. Some shapes, such as cushion, radiant and oval cuts, tend to hold and spread colour well, which can make a stone look richer. We can compare shapes with you on video before you decide.
Coloured accents
You do not need a coloured centre stone to enjoy colour. Small pink, blue or yellow lab grown diamonds can sit on the shoulders, form a hidden stone under the centre or run along a wedding band. A white diamond with a ring of soft pink accents, or a yellow centre with white side stones, are both popular ways to mix colour and sparkle.
Wedding band planning
A colourful stone can sit beside a plain band, a diamond band or a band that echoes the colour. We plan the pair together so they sit comfortably side by side.
