The sighting: Actress Rose Byrne attended the 2026 Oscars in a lovely floral Dior gown and some truly noteworthy jewelry. It was a look that instantly caught the attention of every jewelry lover watching the red carpet – and we’ve got all the details.

The jewels: Rose Byrne’s jewelry was by Taffin, the one-of-a-kind high jewelry line by James Taffin de Givenchy. Taffin is known for non-traditional shapes, unusual stones, and unexpected juxtapositions, all of which are evident in Byrne’s Oscars jewels.

The showstopper here is the necklace: it’s a sculptural torque in delicate gold with an asymmetrical bypass design featuring a 22.58 carat fancy yellow brown pear-shaped diamond and hand-painted chocolate enamel elements. The design feels like an abstract floral when paired with this dress, but I can’t tell if that’s intentional or coincidence.

Byrne also wore a second Taffin piece, a rose gold and blue ceramic ring with a fancy deep brown-cognac 16.54 carat Ashoka by William Goldberg diamond sourced from Botswana.

As Taffin designer James de Givenchy told Town & Country:

“I’ve always been drawn to natural diamonds that exist outside the traditional white spectrum. […] These stones carry a depth and warmth that feels very alive. […] Antique cuts have a softness and irregularity that I find incredibly appealing—they reflect light in a more intimate way. The ceramic setting frames the stone with a rich depth of color, allowing the warmth of the diamond to really emerge.”

The trends: Torque necklaces still aren’t the most common everyday style, but we’ve seen a huge increase in their popularity in recent years.

The same goes for “Desert Diamonds” in shades from sand to brown – this category is the focus of DeBeers’ latest big PR push and the trend certainly seems to be doing quite well on red carpets.

And finally, antique diamonds, brown hues, and Earth tones in general are all big this year!

What do we think? This is so lovely and interesting.

I love everything about it. The subtle movement of the torque’s delicate form, the way that the abstract necklace echoes the asymmetrical floral embellishment on the actress’s gown, the glint of those extraordinary colored diamonds!

This Dior is a classically lovely dress that would have gone with any number of more traditional necklaces, but instead of leaning into the gown’s sweetness with a princess-ey white diamond fringe necklace or similar, Byrne and her stylist Kate Young elevated the entire ensemble by choosing this restrained yet lush Taffin beauty instead.

A master class in red carpet styling! And yes, I am delighted that she’s rocking diamond studs with this necklace instead of leaving her earlobes bare.

Judgement: 19/10 for this exquisite high jewelry moment
