Pink Diamond That Could Fetch $6M) If colored diamonds are your interest rather than auctions, our [lab-grown and natural colored diamonds](/colored-diamonds) are the place to see the same color families at everyday sizes. More on that at the end. ## What Fancy Intense, Fancy Deep and Fancy Vivid Mean Most diamonds in jewelry are graded on the familiar D-to-Z scale, which runs from colorless to light yellow. [GIA explains](https://www.gia.edu/fancy-color-diamond/buyers-guide) that when a diamond falls outside that scale, it is considered a colored diamond, sometimes called a fancy-color diamond. Colored diamonds get a different kind of grade. Instead of a letter, the report gives a description of the color and its strength. On GIA Colored Diamond Grading Reports, [colored diamonds are graded](https://www.gia.edu/fancy-color-diamond/buyers-guide) "in order of increasing color strength" through these terms: 1. Faint 2. Very Light 3. Light 4. Fancy Light 5. Fancy 6. Fancy Intense 7. Fancy Vivid 8. Fancy Dark 9. Fancy Deep So when you read the lots above in plain English: - **Fancy Intense Pink** (the 8.63-carat lead lot) sits one step above plain Fancy on that list. GIA notes that [Fancy Intense and Fancy Vivid generally command higher prices](https://www.gia.edu/fancy-color-diamond/buyers-guide). - **Fancy Pink** (the 8.11-carat stone) is the grade just below Fancy Intense. The two pinks have different estimates, but those figures alone cannot tell you why. - **Fancy Vivid Yellow** (the 18.03-carat stone) has a Fancy Vivid color-strength grade. GIA points out that a yellow diamond with [more color than Z is graded differently](https://www.gia.edu/fancy-color-diamond/buyers-guide), and for these stones a more vibrant color typically means a higher price. - **Fancy Deep Blue** (the 2.88-carat pear-shaped stone in a ring) is the last grade on GIA's list of increasing color strength. Blue is a special case. A [Sotheby's New York catalog essay](https://www.sothebys.com/en/digital-catalogues/high-jewelry-1) explains that blue diamonds owe their color to trace amounts of boron and cites GIA's estimate that only 0.3% of colored diamonds submitted to its laboratory are predominantly blue. The same essay notes that most blue diamonds show a gray modifying color, which is why a pure, unmodified blue is singled out when a catalog describes one. **Read the Grade in Full:** A colored diamond's grade is a phrase, not a letter. Read every word: the strength term, the main color and any modifying color named before it all describe what you will actually see. ## Why an Unmounted Pink of This Size Draws Attention JCK identifies the 8.63-carat stone as the sale's lead lot and describes its color grade, weight and unmounted presentation. **Color strength.** It is graded Fancy Intense, one of the two grades GIA singles out as generally commanding higher prices. **Size.** At more than eight carats, it is one of two pinks above that weight in the sale's top lots, alongside the 8.11-carat Fancy Pink. **It is unmounted.** JCK describes the diamond as loose rather than set in jewelry. The supplied sources do not identify a laboratory report for this lot; check Sotheby's listing for any further documentation. Sotheby's jewelry department page, accessed November 2, 2026, says it sold the [CTF Pink Star](https://www.sothebys.com/en/departments/jewelry), a 59.60-carat oval Fancy Vivid Pink Internally Flawless diamond, in Hong Kong for $71.2 million; the house calls that the world record price for any diamond or jewel. At Sotheby's spring High Jewelry auction in Geneva, a [4.12-carat fancy pink diamond ring](https://nationaljeweler.com/articles/14971-white-diamonds-lead-sotheby-s-auction-blue-diamond-does-not-sell) was among the top five lots and sold to a private buyer from Asia for $1.5 million, according to National Jeweler on May 14, 2026. For another Geneva pink, see our [article on a pink diamond at auction](/blog/bulgari-pink-diamond-christies-geneva). ## Reading an Auction Estimate If you have never followed an auction, an estimate can look like a price tag. It isn't. It is the auction house's own estimate for that lot in that sale, not a guaranteed sale price; a lot may also go unsold. The same National Jeweler report says that a 6.03-carat Fancy Vivid Blue diamond, expected to be the spring sale's top lot, [went unsold](https://nationaljeweler.com/articles/14971-white-diamonds-lead-sotheby-s-auction-blue-diamond-does-not-sell). A few plain points for a first-time reader: - **Currency.** JCK reports this sale's estimates in Swiss francs alongside approximate US dollar figures. - **What the estimate covers.** Check Sotheby's published terms for this sale to find out how the buyer's premium is treated and what additional charges may apply. - **Not a value.** An estimate says nothing about what a stone will be worth later. Diamonds are not investments, and a colored diamond bought at auction is a jewel, not a savings plan. **Check the Lot Page:** For details not given in JCK's report, consult Sotheby's own listing and the sale's published terms. ## How the Stones We Sell Compare Nothing we sell is in this sale. If pink is what appeals to you, browse smaller stones in the same color family and compare their listed prices and reports; they are not the auction lot. Our [colored diamonds, lab-grown and natural](/colored-diamonds) are where to look for pink. Every diamond we sell comes with a GIA or IGI grading report, so the color grade you read is the laboratory's, not ours. Here is how we'd think about spending on a pink: - **Put the money into color you can see.** In a colored diamond, the color is the point. A clarity grade you can't see with the eye matters far less than a color that looks right to you in daylight. - **Consider a softer grade.** A Fancy Light or Fancy pink might be the shade you prefer. If the stronger grade doesn't look different enough to you to justify the step up, take the softer one. - **Look at lab-grown.** Lab-grown diamonds usually cost less than comparable natural ones. If a lab-grown pink looks the way you want, we'd recommend it. Our [honest comparison of lab-grown and natural diamonds](/blog/lab-grown-vs-natural-diamonds) sets out the difference, and our guide to [reading a GIA or IGI report for a lab-grown diamond](/blog/certified-lab-grown-diamonds-read-gia-igi-report) shows where the report says how the stone was made. - **Or choose a different gem in the same color.** A pink sapphire is a different gem from a diamond, but if you love pink, compare our [certified pink sapphires](/gemstones/sapphires/pink), each with a gemological laboratory report, with the diamonds that appeal to you. Every order ships insured, with a signature on delivery, and we pay the import duty on orders to the US. **You don't need an auction paddle to wear pink: choose the color you love, at a size that fits your budget, with the laboratory report in hand.** ## Frequently asked questions **Does Sotheby's sell jewelry?** Yes. According to its jewelry department page, Sotheby's holds live and online jewelry auctions through the year in New York, Geneva, Hong Kong, London, Paris and Milan, and also lists some jewelry for private sale. **How much of a percentage does Sotheby's take?** For the buyer's premium applicable to this sale, check Sotheby's own sale terms rather than relying on a figure quoted elsewhere. **Which auction house is best for jewelry?** We don't rank auction houses. If you are buying or selling, compare each house's published terms, fees and specialist contacts for the kind of piece you have in mind. **Is a pink diamond at auction a good investment?** Diamonds are not investments, and we never suggest buying one for resale. An auction estimate is the house's guide for that sale, not a value or a promise of what a stone will bring later.
