When the poet William Corbett wrote the lines at left he was recounting the experience of viewing a small Willem De Kooning pastel owned by a friend. The description more than adequately summarizes our reaction upon encountering other objects of aesthetic beauty. When such an object, like the Pink Star, is also known to possess truly rare physical attributes, it elicits an intellectual and sensory double-take that pushes the poetry even further. 

As much as any diamond documented throughout history, the Pink Star is unique. To the true connoisseur, this diamond demands attention. Early 20th century philosopher Henri Bergson in Matter and Memory describes attention as an extraordinary reciprocity between the object and the person encountering it, in which the interactions among perception, memory, reflection and image within that person are wildly unpredictable and dramatic. This is exactly the result of encountering this diamond. In all the attributes that are used to assess such a gem, the Pink Star is dramatic.

This diamond has also led a treasured life since it was manufactured. It was first revealed to the world in 2003 in Monaco at the time of the Grand Prix. Following that introduction it was part of a spectacular group of seven diamonds that were exhibited at the Smithsonian Institution from June to September of that same year. In December of 2004 an intimate group of gem aficionados were given the opportunity to observe this rare diamond in Bangkok, Thailand, where it was worn by Her Royal Highness, Princess Ubolrattana. In July of 2005 the Pink Star was a highlight of the Diamonds Exhibition at the Natural History Museum in London.

Given this context, it is a privilege to document the Pink Star in this GIA Monograph. The following sections detail the many remarkable aspects of this diamond, providing a better understanding of why it holds a special place in of the worlds of both gems and objects d’art.

Color Grading Characteristics of the Pink Star

GIA staff determined that the Pink Star was Fancy Vivid Pink during grading. This fancy grade corresponds to the most saturated color in a light to medium tonal range. Among diamonds described as predominately pink, the various color appearances span from warmer orangy pink to cooler purple-pink. While these colors transition smoothly between hues and grades, the colors most commonly seen at GIA are in the orangy pink, pink and purplish pink ranges.

In GIA’s experience, a Fancy Vivid pink diamond of this size is unprecedented. Within this GIA grade and color description, its next rival is less than half its size. Since the initial grading of this diamond in 2002 to the writing of this monograph, the Pink Star has held the distinction of being the largest Fancy Vivid pink diamond graded by GIA.


There are no words more applicable to the Pink Star than those of French painter Eugene Delacroix. Valiant attempts to characterize its immense size, rich color, and remarkable clarity and purity all fall short. Much has been said about the Pink Star, but it is not enough. The Pinks Star is a true masterpiece of nature, beyond characterization with human vocabulary. It is precisely this elusive beauty that will earn the Pink Star a page in the history books, where attempts to fully capture it will continue for years to come.
