Colored Diamonds 101: How Fancy Colored Diamonds Get Their Hues
Zak here - jeweler, gemstone enthusiast, and the heart behind Quantum Qarat in sunny Phoenix. Over the years, I’ve watched countless people light up the moment they spot a colored diamond sparkling in the studio. We all know white diamonds have their own classic draw, but if you’ve ever stared into a blue or pink diamond and felt that instant whoa - trust me, you’re in good company. Pull up a chair, because I’d love to share the inside story on what makes these fancy colored diamonds so unforgettable, and yes, why they can cost an arm and a leg.
What Are Fancy Colored Diamonds, Really?
Fancy colored diamonds are the true unicorns of the gemstone world. While white (or technically, colorless) diamonds follow the crowd, colored diamonds stand out in bold shades like deep blue, radiant pink, sunny yellow, lush green, and beyond. These magical colors aren’t just some nifty surface paint; they’re born in the heart of the earth through incredible, rare natural twists. According to the Natural Diamonds Council, less than 0.1% of all diamonds found actually come in these dazzling hues. For context, you might have to sift through ten thousand colorless diamonds before spotting just one colored gem - now that’s some next-level rarity! Jewelry Informer.
How Nature Creates These Mesmerizing Colors
People always ask what gives colored diamonds their signature shades. Honestly, it’s pure earth magic and a dash of atomic mischief. Each color has a unique backstory:
- Blue diamonds pick up their dreamy hue from boron slipping into the crystal structure way down in Earth’s mantle. These beauties journey upward over millions of years (and never fail to wow anyone who sees them).
- Pink diamonds are shaped through an intense process called plastic deformaion - basically, the crystal gets bent by insane pressures, forever tinting it with gentle pinks.
- Yellow diamonds owe their cheerful sparkle to nitrogen atoms, which lend that signature lemony shine.
- Green diamonds get their hint of rainforest thanks to millenia of natural radiation exposure.
And red diamonds? You might never see one in your lifetime - there are only about 30 known in the entire world Wikipedia. These are the legend-makers of the diamond world.
Why Are Colored Diamonds So Valuable?
Let’s talk turkey: scarcity shapes value more than anything. The rarest colored diamonds - red, pink, blue, and green - command jaw-dropping prices. When the Argyle mine in Australia shut down recently, pink diamonds practically became myth, with prices shooting up even higher Samuelson's Diamonds.
- Red diamonds: Globally, only a handful known
- Blue diamonds: Super rare and headline-stealing at auctions
- Pink diamonds: The Argyle mine's closure put them in a league of their own
- Yellow diamonds: Easier to come by, although intense yellow specimens are still special

How Color Impacts Grading and What Makes a Diamond Stand Out
I get a lot of folks who assume colored diamonds use the same D-to-Z scale as white ones. Nope! Here, it’s all about the intensity and richness of the color. Gemologists look closely at:
- Hue: Is it blue, pink, yellow, or something totally wild?
- Tone: How light or dark is that color?
- Saturation: How punchy and pure is the hue?
Diamonds that earn “Fancy Vivid” or “Fancy Intense” status are the true standouts for collectors and investors (International Gem Society). If your goal is investment or a once-in-a-lifetime gift, understanding this grading is key - I’m always happy to walk you through the process in person or via phone.
Colored Diamonds: Investment Gems and Heirloom Keepsakes
It may surprise you, but the world’s wealthiest families have quietly passed down colored diamonds for generations. Their insane rarity and the halt in mining (especially for pinks) have eaned them a reputation as wearable savings accounts. If you’re looking at smart ways to pass on real value, colored stones are at the top of the list.

FAQ: Fancy Colored Diamonds
- Are colored diamonds natural or enhanced?
Most colored diamonds you see are naturally formed deep in the earth, though some are color-treated for extra vibrancy. If you’re buying for investment or heirloom value, always ask for a gemstone laboratory report. I’m happy to help with this one-on-one if you ever need advice. - Which colored diamond is worth the most?
Red is in a class of its own in terms of rarity and price tag, but blue and pink diamonds are also sky-high in value - take a peek at the GIA buying guide if you’re curious. - Are colored diamonds a wise investment?
For the rarest grades, absolutely. Colored diamonds are portable, durable, and usually outpace traditional investments thanks to finite supply. For those weighing different metal options too, I’ve written a helpful comparison of white gold and platinum for diamond rings. - How should I take care of colored diamond jewelry?
Avoid chemicals, keep your gemstones in individual soft pouches, and bring them in for the occasional professional checkup. More care tips, restoration, and resizing info are over on our services page.
