Fancy color grades: Fancy, Fancy Intense, Fancy Vivid
Fancy color diamonds are graded by hue (the color itself) and by how strong that color is. On an IGI report the strength reads, from lighter to stronger: Fancy, Fancy Intense and Fancy Vivid.
Each diamond on this page shows its exact grade from its IGI report, for example "Fancy Vivid Pink". Black and brown diamonds are graded by hue only.
| Grade on the report | What it means |
|---|---|
| Fancy | Clear, even color |
| Fancy Intense | Stronger, more saturated color |
| Fancy Vivid | The strongest, most saturated grade |
