At Foxy Diamonds, a coloured stone is never chosen by specification alone. A number in a certificate is a starting point, not a conclusion. Beauty in fancy colour is defined by how tone, saturation, undertone, crystal structure and cut interact — and that interaction can only be understood by looking at the stone itself.
Our selection process follows a deliberate order, and understanding it helps explain why two diamonds with identical certificates can produce completely different pieces of jewellery.
Colour First
Colour is the foundation. It is the element that defines the character of the piece long before any technical specification is considered.
When we evaluate a coloured diamond, we look at the hue itself — but more importantly, at the purity of that hue. Is the saturation even throughout the crystal? Are there undertones that disrupt the harmony of the main colour? Is the tone balanced — not too pale to read, not too dark to suppress brilliance?
A stone with a calm, coherent and well-structured colour will always appear more refined than a technically cleaner stone whose colour lacks depth or inner consistency. In the lab-grown segment, colour is no longer left to geological chance — it can be shaped with intention. This allows us to look not for what happens to exist on the market, but for what truly fits the design and the emotional idea behind the jewel.
Clarity as Support, Not Dominance
Clarity plays an important but deliberately supporting role.
Lab-grown fancy diamonds typically achieve higher clarity at the same budget compared to natural alternatives. This allows us to avoid the compromises that are often inevitable in the natural fancy segment, where exceptional colour frequently comes at the cost of visible inclusions.
For us, clarity is never pursued at the expense of colour. It exists to preserve transparency and structural integrity — not to overshadow the personality of the stone. A VS stone with Fancy Vivid colour will almost always be a stronger choice than a VVS stone with Fancy Light colour.
Shape as a Tool of Expression
There is no universally correct shape for a coloured diamond. Each geometry interacts with colour in its own way:
- **Cushion and radiant cuts** tend to deepen saturation and increase colour density
- **Emerald cuts** highlight tone and internal structure, creating a more graphic effect
- **Oval and pear shapes** soften colour and introduce lightness and movement
The choice of shape is never purely technical. It is a design decision guided by how colour is distributed within the specific crystal, the proportions of the intended setting and the personality the stone expresses. A pink diamond that looks stunning in a cushion might look entirely different — and entirely different in value — in an oval.
Size as the Final Adjustment
In fancy colours, size is never the beginning of the conversation. Visual presence is determined by colour long before it is determined by carat weight.
Our process always starts with colour, then defines clarity, then selects the cut — and only after that adjusts size within the remaining balance. A smaller stone with a strong, coherent and vivid colour will almost always feel more precious than a larger diamond whose colour lacks presence or stability.
In fancy colours, visual impact outweighs carat weight. Proportion matters more than absolute size.
What This Means for You
When you choose a fancy colour diamond at Foxy Diamonds, the process begins with an honest conversation about what colour means to you — its hue, its intensity, its emotional character — and then works forward through clarity, shape and size.
We do not present a list of stones filtered by carat and clarity. We present a curated selection where colour is already the primary criterion, and every other parameter exists to support it.
Lab-grown fancy diamonds allow us to work with a level of precision that natural stones rarely offer — stronger colour, higher clarity, greater consistency and a more controlled aesthetic result, while preserving the same physical and optical nature of diamond itself.
