Kylie Jenner wore the 2026 Victoria's Secret Fantasy Bra, made by Jacob & Co, on the runway in Los Angeles on October 18, 2026. It is reported to be worth about US$50 million, with a natural 75.54 carat fancy vivid yellow diamond at the center and about 4,400 other diamonds around it (National Jeweler, Forbes Australia, Complex). It is the first Fantasy Bra on the runway since 2018.
We do not make bras, so we use the story to look at the stone: what has been reported, what fancy vivid yellow means, how big 75.54 carats is in millimeters, and how to get the yellow diamond look in lab grown diamond. Prices were checked on October 28, 2026.
Every figure below is as reported by the outlet named. We have not seen a grading report, so we have not confirmed any of these figures, the value included. Where outlets disagree, the table says so.
| Detail | What is reported | Reported by |
|---|---|---|
| The show | Kylie Jenner wore it at the Victoria's Secret Fashion Show in Los Angeles on October 18, 2026. | National Jeweler, Forbes Australia, Complex |
| Maker | Jacob & Co. | All of the outlets below |
| Value | About US$50 million. None of the reports we read say who valued it. | National Jeweler, Complex, Maxim, Who What Wear |
| Center stone | A natural 75.54 carat diamond, color fancy vivid yellow. | National Jeweler, Complex, Maxim, Man of Many |
| Clarity of the center stone | VS2. Maxim and Man of Many say the grade is from GIA. | National Jeweler, Maxim, Man of Many |
| Cut of the center stone | Radiant cut. Other outlets do not state a shape. | National Jeweler, Forbes Australia, Maxim, Man of Many |
| Beside the center stone | Two round brilliant white diamonds totaling 11.85 carats. | National Jeweler, Forbes Australia |
| Other diamonds | 4,409 more diamonds, or 4,410 counting the center stone, weighing about 1,373 carats (1,373.39 in some reports). Outlets differ on whether that weight includes the yellow diamond, so counts vary. | Forbes Australia, Complex, Maxim, Irish News (Press Association) |
| Last time | The first Fantasy Bra on the runway since 2018, when Elsa Hosk wore it. | Complex, Who What Wear, IBTimes UK |
Some Australian headlines said "$70 million", a rounded currency conversion of the same US$50 million. The text of the same story from Australian Associated Press, published by the Newcastle Herald, gives US$50 million, or A$72 million, and Man of Many gives A$71 million.
None of the reports we read give the length or width of the yellow diamond or a grading report number, and outlets disagree on the stone count (4,409 or 4,410). Treat every number above as reported, not confirmed.
The Gemological Institute of America (GIA) grades colorless to light yellow diamonds on its D to Z scale, which is based on the absence of color. When a diamond has enough color to show face up, it moves to the fancy color system, which is based on the presence of color. GIA describes fancy color by hue (the color), tone (how light or dark) and saturation (how intense).
For yellow, GIA says the fancy grades typically begin at Fancy Light, since paler yellows are graded on the D to Z scale. GIA says most yellow diamonds in jewelry fall into the four grades below, listed from lighter to stronger color (GIA yellow diamond buying guide, GIA fancy color buyers guide). GIA's full scale also includes Fancy Deep and Fancy Dark.
| GIA grade | Notes from GIA |
|---|---|
| Fancy Light | Where yellow diamonds typically begin. Paler yellows are graded on the D to Z scale. |
| Fancy | The next step up in GIA's order of color strength. |
| Fancy Intense | Fancy Intense and Fancy Vivid generally command higher prices. |
| Fancy Vivid | In general, the stronger and more saturated the color, the higher the value, with Fancy Vivid diamonds the most prized. |
GIA says natural yellow diamonds are extremely rare: only about one out of every 10,000 carats mined is a natural fancy color diamond of any color. In the same guide, GIA calls yellow the most affordable of all the fancy color varieties. GIA also says the radiant cut is highly favored for yellow diamonds, which is the cut reported for the Fantasy Bra stone.
Other yellow diamonds made the news in 2026 too. On August 10, Marie Claire Australia and Cosmopolitan both reported on the engagement ring of Formula 1 driver George Russell, a large yellow diamond with white side stones. The jewelry experts they quoted said it looks like a fancy vivid yellow and estimated it at roughly 7 to 10 carats. Those are estimates, not confirmed details.
On September 11, HELLO! reported that Princess Alexandra of Hanover's engagement ring has a yellow diamond. Royal Watcher describes it as a 4.8 carat Fancy Yellow diamond between two trillion cut diamonds. More of the year's rings are in our guide to celebrity engagement rings of 2026.
Kylie Jenner also wore large pear shaped diamond drop earrings at the 2026 BAFTAs, according to Katerina Perez and The Diamond Collective. We cover those and other famous earrings in celebrity diamond earrings of 2026.
A 1 carat round diamond is 6.5 mm across. At 75.54 carats the Fantasy Bra stone weighs about 15.1 grams, roughly the weight of three US nickels (5 g each, per the US Mint coin sizes list). Weight builds in all three directions, so 75 times the weight is not 75 times the size. The stone is about 4.2 times as long.
Four outlets report a radiant cut, so we can estimate the size as a radiant. The table uses our radiant size model at its classic length to width ratio of 1.30.
| Radiant cut diamond | Length × width | Depth |
|---|---|---|
| 1 carat | 6.24 × 4.80 mm | 3.36 mm |
| 10 carats, the largest center stone on our yellow radiant ring with baguette shoulders | 13.4 × 10.3 mm | 7.2 mm |
| 30 carats | 19.4 × 14.9 mm | 10.4 mm |
| 75.54 carats, our estimate for the Fantasy Bra stone | 26.4 × 20.3 mm | 14.2 mm |
For scale, 26.4 mm is longer than a US quarter (24.26 mm across), and 20.3 mm is a little narrower than a US nickel (21.21 mm). A round diamond of 75.54 carats would be about 27.5 mm across. See a 30 carat radiant on your hand. Our size tool stops at 30 carats, so it cannot draw the full 75.54 carats, though 30 carats is already about 19.4 mm long.
We used the method from our guide to famous engagement rings at actual size. Dimensions scale with the cube root of the carat weight, starting from the 1.00 carat size of the shape. The cube root of 75.54 is about 4.23, so every dimension of a 1 carat radiant (6.24 × 4.80 × 3.36 mm) is multiplied by 4.23.
These are estimates. No outlet we read gave the real measurements or the stone's length to width ratio. By the same model, a squarer stone of the same weight would measure about 22 mm on each side, and a longer one would be narrower, so the real stone may differ from our figures. For more on how carat weight and millimeters relate, see our radiant cut guide, carat to mm article and how big a 5 carat diamond is.
We make rings, a bracelet and other pieces with fancy yellow lab grown diamonds. A lab grown diamond is identical in every physical and optical property to a mined diamond. Every Ronora lab grown diamond has an Excellent cut and VVS-VS clarity, and each product page lists the yellow color.

The Fantasy Bra stone is reported as a radiant cut, the shape GIA says is highly favored for yellow diamonds, so our yellow radiant rings are the closest match in shape. The yellow radiant ring with baguette shoulders has center stones from 2 to 10 carats, about 7.9 × 6.1 mm at 2 carats and about 13.4 × 10.3 mm at 10 carats. See a 10 carat radiant on your hand. Asscher and oval pieces suit the same color if you prefer another outline.
| Piece | Center stone | Color listed on the product page |
|---|---|---|
| Yellow radiant solitaire ring | Radiant, 1 to 4 carats | Fancy Vivid Yellow |
| Yellow radiant halo ring | Radiant, 1 to 4 carats | Fancy Yellow |
| Yellow radiant ring with baguette shoulders | Radiant, 2 to 10 carats | Fancy Yellow |
| Asscher yellow three stone ring | Asscher, 2 to 10 carats | Fancy Vivid Yellow |
| Yellow oval eternity band | Ovals, about 3.5 total carats | Fancy Vivid Yellow |
| Yellow radiant tennis bracelet | Radiants, from 12.35 total carats | Fancy Yellow |
Every lab grown diamond of 1 carat or more has its own IGI report. Every gold piece comes with an SGL jewelry certificate and every platinum piece with an ITPL jewelry certificate. Silver pieces have no jewelry certificate. The oval eternity band is set with stones under 1 carat each, so it does not carry a single stone report.

Ronora is not connected to, or endorsed by, anyone named in this article. Carat weights and prices are reported estimates.
It is reported at about US$50 million by National Jeweler, Complex and Maxim, and outlets describe it as the most expensive Fantasy Bra to date. None of the reports we read say who valued it. Some Australian headlines say $70 million, a rounded currency conversion (about A$72 million) of the same US$50 million.
It is reported at 75.54 carats and a radiant cut. Sized as a radiant at the classic 1.30 ratio, we estimate about 26.4 × 20.3 mm and 14.2 mm deep. No outlet we read published the real measurements, so treat our figures as an estimate.
It is a GIA color grade for a diamond with a strong, saturated yellow. GIA lists the yellow grades in order of increasing color strength as Fancy Light, Fancy, Fancy Intense and Fancy Vivid, and calls Fancy Vivid the most prized of the fancy grades.
Outlets report the center stone and the other diamonds as natural. Ronora's yellow diamonds are lab grown and identical in every physical and optical property to mined diamonds. The yellow pieces in this guide list their color as Fancy Yellow or Fancy Vivid Yellow on the product page.
