Color
Diamond’s color consideration is a very important factor that affect its beauty. Diamonds are commonly thought to be colorless. While they are available in a broad range of colors and hues as yellow, pink, grey, brown and blue. As well, red, purple, and green are some of the most unique colors.
Naturally colorless diamonds are extremely rare, whereas subtle yellow hue is the most common. Hence, the majority of diamonds used in jewelry are nearly colorless with yellow or brown tint.
Color variations can have a significant impact on a diamond's value. It can make a difference in the value of two diamonds with the same clarity, weight, and cut. Colorless diamonds are the most valuable within the normal color range since they are the rarest.
For color-grading
the GIA D-to-Z scale is the industry commonly used standard. Each letter represents a color range based on the tone and saturation of a diamond.
Diamond whose color is beyond Z are denoted as "fancy" color diamonds and are graded using their own scale and terminology. The more intense the color implies higher value, therefore, the brightest, purest hues are the most sought.
Helpful Tips:
• The bigger the diamond, the more noticeable the color.
• The delicate difference in color can make a huge impact on the value.
• When a diamond is mounted, the white or yellow metal can affect the diamond apparent color, hence its challenging to determine its grade accurately.
◦ Yellow gold settings can mask the yellow or brown tint, while white metal makes it more obvious.
◦ On the other hand, white metal gives the colorless diamonds icier appearance.
• It’s important to note that diamond color can be lightened, removed, or created using a combination of high pressure and high temperature treatments to change or add color to diamonds.
