Got boron? If a diamond crystal contains trace elements of boron, you can end up with a blue diamond. Currently there are nine grades defined for blue diamonds.
- Faint Blue (sample GIA report)
- Very Light Blue (sample GIA report)
- Light Blue (sample GIA report)
- Fancy Light Blue (sample GIA report)
- Fancy Blue
- Fancy Intense Blue (sample GIA report)
- Fancy Vivid Blue
- Fancy Dark Blue
- Fancy Deep Blue (sample GIA report)
Most ‘blue’ diamonds will have a secondary color, which could be grey, green or yellow. With the secondary color’s you end up with color descriptions of all types like fancy vivid green-blue, fancy light greenish blue or fancy intense blue-green etc. Finding a blue diamond without a color modifier is almost as rare as finding a blue diamond itself 😉
