Only those yellow diamonds with a deep, beautiful color are given special recognition
and called "fancy" yellow.
There are said to be more than 20 polished fancy yellow diamonds in existence that weigh over 100 carats. Most of these were mined in South Africa. India and Brazil were the main sources of diamonds for many years before the discovery of diamonds in South Africa in 1866, but they produced few yellow diamonds.

There were many yellow diamonds among those mined in Cape Province of South Africa, and diamond dealers therefore refer to yellowish diamonds as "cape." South African production saturated the market with yellowish diamonds, resulting in much lower prices. Among these, only those with a deep and beautiful color are given special recognition and called "fancy" yellow diamonds.

The marquise-cut fancy yellow diamond as shown in the photograph on the next page has a lemon color and a beauty that seems to overflow from the stone.
This is a so-called "canary" fancy yellow diamond. Both the brilliance and the balance of the mosaic pattern in this gemstone are exceptional, and its perfectly balanced outline gives an impression of refinement. Compared to colorless diamonds of similar size and shape, this particular gemstone is by far more beautiful. A fancy yellow diamond as beautiful as this one is rarely encountered. Since each gemstone is unique, it is important to compare them individually and determine which is more beautiful. As with any colored gemstone, the beauty of a fancy-colored diamond is determined primarily by its color, then by the balance of its transparency, brilliance, scintillation, and overall appearance.

Notably, fancy-colored diamonds are not often fashioned as round brilliant cuts. In order to take full advantage of the rough material and produce a deep, beautiful color when viewed face-up, the cutter considers each fancy-colored diamond carefully and polishes them into various shapes.
