Find Out Good Colored Diamonds
Here’s a rundown of what to expect with colored diamonds :
- Reds and pinks: The rarest of colors, these diamonds get their ruby hues thanks to an irregular atomic structure. “When the spectrum of light enters it, it’s actually exciting certain electrons in the stone to different wavelengths, making it appear red,” Cuellar says. In November, British jeweler Laurence Graff paid a record $46 million for a ring featuring a 24.78-carat rare pink diamond.
- Blues: Colored by trace amounts of boron, blues include the allegedly cursed Hope Diamond and the Blue Heart Diamond, both today held by the Smithsonian Institution in Washington, D.C.
- Yellow: Nitrogen, usually an unwanted quality in mostly colorless natural diamonds, can create expensive, vivid canary-yellow diamonds.
- Green: Radiation causes the color, but gemological labs often cannot determine if the radiation was natural or man-made. “The person who has it has something of no value,” says Cuellar.
- Champagne, cognac or chocolate: Skip these newly popular colors, says Cuellar. “You might as well just burn your money,” he says.
