Fancy Lemon Yellow Diamonds
There are many descriptive terms for a Fancy Yellow diamond. The most prominent that come to mind include Saffron, Canary, Buttercup and Lemon – each one conveying the intensity of citrus yellow exhibited by this exquisite colour. Yellow is probably the perfect diamond colour for Summer and we thought this would make a wonderful addition to the blog. The connection with warmth, sunlight, citrus, and warmth are all captured within this highly distinctive diamond colour.
GIA Grades of Fancy Yellow Diamonds
The Gemological Institute of America, classifies yellow diamonds with varying levels of intensity in the following grades :
- Fancy Vivid Yellow
- Fancy Intense Yellow
- Fancy Yellow
- Fancy Light Yellow
Other diamond grading laboratories use similar terms, but with subtle differences, HRD laboratory for example omits any reference to the term “vivid” within their own classification. Diamonds exhibiting a greater depth of colour than Z on the colour scale, tend to be classified as fancy coloured yellow. The most prized are those yellow diamonds described as “Canary” which describes the colour perfectly.
Why are Some Diamonds Yellow?
The presence of Nitrogen in the diamond usually results in the Yellow colouration. Carbon atoms within the crystal structure, during the formation process are replaced by Nitrogen atoms, changing the way the diamond interacts with light. Nitrogen absorbs blue and violet light resulting in Yellow light being reflected back to the eye. Even a low concentration can result in a significant colouration.
Since many Yellow diamonds were discovered in the Cape Province of South Africa, the term “Cape” became connected with Yellow diamonds and is still used today, despite the occurence in other parts of the world. Within the diamond Industry we use other terms denoting lesser shades such as Light Cape (LC), Top Light Cape (TLC), Silver Cape (SC) and Top Silver Cape (TTSC) to name a few, although these are not fancy colour descriptions. Top Top Silver Cape (TTSC) describes a very light shade of natural non-fancy yellow colour.

Prices and Availability
The above diamond ring is a customised version of one of our fancy diamond engagement rings, R1D037S. Instead of being set with a white round brilliant cut diamond, the four claw setting holds a fancy intense yellow diamond, 1.00cts in size above the very white melee of micro-pavé set diamonds. This is further complimented by the micro-pavé wedding ring which sits below, flush against the engagement ring. Being the second most available colour of diamond, it is possible to source most sizes of natural fancy yellow diamond, and the cost of such a ring as that shown would typically run from approx. £8000 upwards in 950 Platinum, with a Fancy Intense Yellow GIA certified 1ct round brilliant cut diamond at the centre.
