What Selena Gomez Wore to Her Birthday Party

Selena Gomez turned 33 in July 2025. She celebrated with a 1970s themed birthday party at the Hollywood Roosevelt Hotel, with Taylor Swift and Benny Blanco among the guests.

Photos from the night show Gomez in a sequin jumpsuit and a faux fur coat, with a diamond necklace layered near her collarbone. Brilliant Earth confirmed on its own website that the necklace is a custom lab diamond piece from its Jane Goodall Collection. Multiple outlets reported the necklace carries more than 20 carats of diamonds total.

The Jane Goodall Collection Behind the Necklace

Brilliant Earth launched the Jane Goodall Collection in 2024 with primatologist and conservationist Dr. Jane Goodall. The design is built around a banana leaf motif, inspired by Tanzania, where Goodall did much of her early research on chimpanzees.

Every item in the Jane Goodall Collection uses repurposed gold and lab grown diamonds. Brilliant Earth also donates 10% of net proceeds from the collection to the Jane Goodall Legacy Foundation Fund, which supports conservation, research, and education work tied to the Jane Goodall Institute.

The jewelry Brilliant Earth sells from this collection runs from around $850 for stud earrings up to several thousand dollars for larger necklaces and rings. Gomez’s necklace was a custom version built specifically for her, so it isn’t something you can order off the website. But the same design and materials show up across the necklaces, earrings, and rings Brilliant Earth does sell.

Why Lab Grown Diamonds Made This Necklace Possible

A necklace with more than 20 carats of diamonds usually comes with a price that puts it out of reach for almost anyone. Lab grown diamonds change that math.

Lab grown diamonds have the same chemical makeup, hardness, and sparkle as natural diamonds. The only real difference is where they come from. A lab grown diamond is grown in a lab instead of pulled from the ground, and that difference in origin is also why lab grown diamonds cost significantly less than natural diamonds of the same size and quality.

That price gap is exactly why a necklace like this is possible outside of a museum case. You get more carat weight in a bigger design, without needing a celebrity budget to pull it off.

Where to Shop the Look

You can’t buy the exact necklace Gomez wore since it was made specifically for her. But Brilliant Earth sells other jewelry from the Jane Goodall Collection with the same look and story.

The Jane Goodall Collection includes necklaces, huggie earrings, stud earrings, and rings, all made with repurposed gold and lab grown diamonds. If you want a diamond necklace with a similar feel, this collection is a good place to start.

If you want more diamond necklace options outside this specific collection, Brilliant Earth carries a wide range of styles, from simple solitaire necklaces to layered diamond designs.

Bottom Line

Selena Gomez’s birthday necklace is a good example of what lab grown diamonds make possible. Over 20 carats of diamonds, in a custom design, tied to a collection that gives back to conservation work.

Brilliant Earth’s Jane Goodall Collection lets you buy into that same story on a smaller scale, whether that means an $850 pair of stud earrings or a necklace of your own. Every item uses repurposed gold and lab grown diamonds, and 10% of net proceeds go to the Jane Goodall Legacy Foundation Fund.
