Fancy Yellow Diamonds in Dallas, Texas
The diamond color scale used for white diamonds goes from D to Z. As the letter is closer to Z, it means that the diamond is less colorless and starts to be a bit yellowish in tone, a pale yellow shade. This degrades the diamond and their prices decrease as you get closer to Z.
However, at a certain point, if you "continue on the color scale", the color doesn't look as a faded yellow and instead becomes a beautiful yellow shade - this is the point when the price increases again and the diamond is considered a yellow diamond.
Yellow diamonds belong to the special family of natural fancy color diamonds. Regular diamonds that due to impurities found in them (a fluke of nature) change their color during their formation process - making them everything but regular.
The cause for each color is different, green diamonds get their color due to radiation, the cause for blue color is boron and yellow diamonds get their color due to the existence of nitrogen molecules which absorb blue light. This impurity is also what gives orange diamonds their color.
YELLOW DIAMOND INTENSITY LEVELS
White diamonds are graded on a color scale of D to Z, with D being a colorless diamond and Z having a distinct yellow or brown tint. If the scale were to continue past Z—all the way to a rich, yellow color—you'd have a Fancy Vivid Yellow Diamond. In other words, yellow diamonds are fully saturated with yellow and carry no traces of whiteness whatsoever.
The GIA color grading scale for yellow diamonds is:
- Very Light
- Fancy Light
- Fancy Intense
- Fancy Vivid, Fancy Deep or Fancy Dark
