by jewelers, collectors, and consumers. Notable pink diamonds such as the
Darya-i-Nur (reported to weigh more than 175 ct), the 28.15 ct Agra, and the

environment—a viewing box that eliminates
visual distractions and shields external

effect of tone and saturation on the color

regions of tone and saturation in color space
and vary by hue, since different colors reach

The M ajestic Pink Diamond Br acelet: Milestones
1985
The Argyle diamond mine of Western Australia begins production. For a period of several years,
it will be the single largest producer of diamonds in the world. A small percentage of the mine’s
output will consist of pink diamonds.
L ate 1980s
The fi rst pink diamonds are acquired for a one-of-a-kind bracelet.
E a r ly 1990s
The set of 204 pinks is complete.
1994
Carven French creates the pink diamond bracelet.
2009
• The diamonds are carefully removed from the mounting and submitted to GIA for
Colored Diamond Identification and Origin Reports. Of the 204 diamonds, 161 are
subsequently recut to enhance their color.
• In mid-2009, the diamonds are examined for the creation of a GIA Monograph.
• Later that same year, the piece is named the Majestic Pink Diamond Bracelet.
