Yellow diamonds are an exceptional choice, showcasing a stunning beauty that truly sets them apart. Whether you’re captivated by their colour, their fascinating history, or their classic charm in vintage designs, it’s clear that a yellow diamond is an essential addition for any serious diamond jewellery enthusiast.
If you’re considering adding a yellow diamond ring or other accessory to your jewellery collection, it’s important to grasp the different elements that affect its quality. This guide will help you navigate the key factors to keep in mind when assessing a yellow diamond, ensuring you make a well-informed and confident choice.
Understanding the “4 Cs” of Yellow Diamonds
The quality of a diamond is mainly evaluated through the “4 Cs”: Colour, Cut, Clarity, and Carat weight. For yellow diamonds, these factors have unique characteristics that distinguish them from diamonds that are colourless.
Colour Intensity
Why Colour Intensity is Important
The key element that influences the value of a yellow diamond is its colour intensity. In contrast to white diamonds, which are valued for their lack of colour, yellow diamonds are celebrated for their brightness. The deeper and more vibrant the yellow shade, the rarer and more precious the diamond is.
Colour Grading Scale
Yellow diamonds are assessed on a scale from “Fancy Light” to “Fancy Vivid,” with the intensity of colour increasing along the spectrum.
- Faint: A very light yellow tint, almost imperceptible.
- Very Light: A noticeable yellow hue but still quite light.
- Light: A discernible yellow but not yet intense.
- Fancy Light: A soft, gentle yellow tone.
- Fancy: A mid-level intensity, offering a clear and vibrant yellow.
- Fancy Intense: A rich and more saturated yellow.
- Fancy Vivid: The highest and most valuable grade, showcasing an exceptionally bright and saturated yellow.
- Fancy Dark: A deep, rich yellow that is darker in tone, often has a subtle hint of brown or gray, giving it a more muted and subdued appearance.
- Fancy Deep: A strong, deep saturation of yellow that is darker than Fancy Intense but without the subdued tones of Fancy Dark. It combines both intensity and depth, giving the color a dramatic and vibrant look while maintaining its richness.
Cut
The Importance of Cut in Yellow Diamonds:
The cut of a diamond significantly influences its shine and brilliance, and this is just as important for yellow diamonds. In the case of coloured diamonds, the cut is essential for bringing out the stone’s colour intensity to its fullest.
Ideal Cuts for Yellow Diamonds:
Some of the most sought-after cuts for yellow diamonds are:
Cushion Cut: This style enhances the diamond’s depth and colour, making it a popular choice for yellow stones.
Radiant Cut: Renowned for its dazzling facets, the radiant cut provides remarkable sparkle while amplifying the diamond’s colour.
Oval and Pear Shapes: These elongated designs increase the surface area, boosting the diamond’s colour and giving it a more substantial appearance.
Clarity
Clarity refers to the presence of internal flaws (inclusions) or external flaws (blemishes) found in a diamond. While clarity plays an important role for white diamonds, it is less critical for yellow diamonds because their rich colour can conceal minor inclusions.
Clarity Grading Scale:
Flawless (FL) / Internally Flawless (IF): No visible inclusions or blemishes, even when viewed under 10x magnification.
Very Very Slightly Included (VVS1 and VVS2): Incredibly small inclusions that are hard to spot under magnification.
Very Slightly Included (VS1 and VS2): Minor inclusions that are difficult to see without magnification.
Slightly Included (SI1 and SI2): Inclusions may be visible under magnification but are generally not seen with the naked eye.
Included (I1, I2, and I3): Inclusions are noticeable without magnification and can impact the diamond’s brilliance.
Carat Weight
Carat weight indicates the size of a diamond, with one carat being equivalent to 200 milligrams. Larger yellow diamonds are naturally scarcer and thus hold greater value. Interestingly, yellow diamonds often showcase their colour more vividly than white diamonds, meaning that even smaller yellow diamonds can still create a striking impression.

Fluorescence
Fluorescence is the phenomenon where a diamond gives off a gentle glow when it comes into contact with ultraviolet (UV) light. In the case of yellow diamonds, strong fluorescence can occasionally lead to a cloudy look, which may diminish the stone’s sparkle.
To achieve the clearest and most vibrant gem, it’s best to look for yellow diamonds that have little to no fluorescence or only faint fluorescence.
Certification
When buying a yellow diamond, make sure to choose one that includes a grading certificate from a trusted gemmological lab. This certificate offers an impartial evaluation of the diamond’s 4 Cs, helping you make a well-informed purchase.
Setting and Metal Choice
The type of metal you choose can really affect how your yellow diamond looks. Yellow gold often brings out the warm hues of the stone, while white gold or platinum can provide a bold contrast that makes the diamond’s colour stand out beautifully.
When considering purchasing a yellow diamond, it’s important to grasp the subtleties of colour intensity, cut, clarity, and carat weight. This knowledge will guide you in choosing a gem that genuinely embodies your style and taste. These vibrant stones are a worthwhile investment, so taking the time to assess their quality will help you discover a piece that is both exquisite and valuable.
