GIA Diamond Color Scale
The Gemological Institute of America (GIA) is the most widely recognised authority on diamond grading. The GIA diamond color scale is used to grade diamonds from D (colorless) to Z (light yellow or light brown). Here is a breakdown of the GIA diamond color scale:
-
D: Absolutely colorless (Highest quality)
-
E–F: Colorless (Very high quality)
-
G–H: Near-colorless (Slight traces of warmth)
-
I–J: Faint yellow or brown tint
-
K–M: Very light yellow or brown tint
-
N–R: Light yellow or brown
-
S–Z: Noticeable yellow or brown (Lowest on standard scale)
It’s worth noting that the color of a diamond is not the same even though different platforms showcase a similar jewellery piece. These colors are hard to distinguish from a naked eye. And thus, we recommend asking your jeweler to give you all the details related to the diamond color and clarity before making a purchase.
Onya uses 100% VVS clarity D-E-F color lab-grown diamonds for all its jewellery. When comparing prices online for different pieces, always ensure you are comparing the same clarity, color, and carat of diamond. For those seeking exquisite quality, Onya offers some of the best lab grown diamond jewelry, combining unmatched brilliance with ethical craftsmanship.
