White or light opal: Translucent to semi-translucent, with play of color against a white or light gray background color, called bodycolor.Photo by Robert Weldon/GIA The Many Colors and Types of Opal The opal that beguiles the main characters in “Uncut Gems” was still in its matrix, similar to this piece of rough opal in matrix. As light travels through this microstructure, it creates a dazzling kaleidoscope of flashing rainbow colors, called play-of-color. As the deposited materials dry, the microscopic silica spheres become compressed into a closely-packed lattice. Opals are formed from centuries upon centuries of seasonal rains that leach microscopic silica particles from sandstone, carrying them deep into underground fissures and cavities. “Any realistic valuation of rough gem material is based on the potential for yielding polished gems and the risk involved in fashioning finished gemstones.”Īdding to that risk is the fact that, unlike most gems, opals are not stones or minerals. “In real life, the opal nodules must be shaped and polished into gems after removing the valueless matrix, which often results in much more weight loss,” explained Nathan Renfro, GIA Graduate Gemologist ® and manager of colored stone identification services at GIA. This means that it would be very difficult – in real life – to evaluate the opal and appraise its value until the matrix was removed. The specimen shown in the movie appears to have several opal nodules (though probably not black opal) inside the matrix of host rock, but that host rock appears to account for the majority of its volume. With opals, as with most gemstones, the final polished stones weigh only a fraction of their rough form. Why?Įthiopian opal ‒ the featured gemstone in the movie “Uncut Gems” ‒ was first discovered in Ethtiopia in 1994. But the auction house he consigns it to values the piece at much less - $150,000 to $225,000. He estimates that the piece weighs between 4,000 to 5,000 carats and, at up to his estimated value of $3,000 per carat, he sees millions coming his way. Sandler’s character is enamored with the opal’s potentially huge sale price. Garnett is captivated to such an extent that he cannot play well without owning it. “They say you can see the whole universe in opal, that’s how … old they are,” Sandler’s character, Howard Ratner, a jeweler and gem dealer on 47th Street in New York City, tells basketball star Keven Garnett when he shows the opal to him. A giant piece of Ethiopian opal, still in its matrix, is smuggled to New York. The magical quality of opals is the central metaphor of the 2019 movie “Uncut Gems,” starring Adam Sandler. They are looking at an Ethiopian opal in matrix that Sandler's character, Howard Ratner, is putting up for auction in the movie.
