Diamond Color

Diamond rings shine so bright on fingers, the secret is loose diamond work like a prism. It catch natural light and break it into many colorful sparkles. The diamond’s own color acts like a light filter inside. If a diamond is clear and no color, it can reflect more bright rainbow flashes. That make colorless diamond more expensive than light yellow ones. Diamond color grade is a rule to mark how yellow a stone is. Higher grade means less yellow tint inside the crystal. Color is one of the four most important C factors. When people pick loose diamonds, they can’t ignore color. Human eyes first notice how shiny a diamond is, and shine level is heavily effected by color.

Grade D: Total no color. It is the top color level, super rare to find.

Grade E: No visible color. Only professional gem tester can find tiny bit of tint inside. This kind of diamond is really uncommon.

Grade F: Colorless grade. Only jewelry experts can spot little color trace, but it still count as colorless range. They are top quality diamonds.

Grade G to H: Near colorless. You can see soft yellow tint only when you put them next to D-F high grade stones. Diamonds of G and H grade still keep great market value.

Grade I to J: Almost no color. Light yellow shade can be detected easily. They have pretty good value for daily wear.

Grade K to M: Strong yellow color, low fire sparkle. Our wedding diamond ring store do not sell these grades, we tell customers do not choose them.

Grade N to Z: Dark yellow tint, bad light performance. Our shop never provide these diamonds, we also advice buyers stay away from them.

Once a diamond finish cutting, outside things can not change its value anymore. Diamond color will not turn yellow as years go by. It is extremely hard to find a full colorless diamond, so D grade stones are rare and costly. Most loose diamonds have natural mixed tint when they form underground, like green, coffee and brown shades. These unwanted color will drop diamond’s worth a lot. Many shoppers ask, which color grade should I pick when buying a diamond? Everyone know the rule: colorless is best, darker yellow means worse quality. D to F are full colorless group. G to J are near colorless. K to M have clear yellow tone. N to Z carry obvious pale yellow, they almost have no collection value. But fun fact, N-Z yellow diamonds match gold metal very nicely. After Z grade, stones with full rich yellow color belong to fancy colored diamond category.

For daily shopping, better choose H or above I color diamonds. I and J grade still fall into near colorless group, but naked eyes can catch faint yellow shade directly. Fancy color diamonds use different grading rule. Their price depend on how bright and vivid their color is. There are many fancy diamond types: yellow, green, blue, brown, pink, orange, red, black, purple and more. All of them are precious fancy gems. Red fancy diamond is the most valuable one among all colored diamonds.
