Celebrity engagement rings / Hailey Bieber
In short: Hailey Bieber’s 2018 engagement ring is an elongated oval diamond solitaire by New York jeweller Solow & Co. The weight was never confirmed; estimates range from 6 to 10 carats, and its value was reported at about US$500,000. In 2024 she began wearing a new oval ring by Lorraine Schwartz.
The ring
To scale
From above, it covers roughly 4.3× the area of a typical 1 carat round diamond. Drawn from the reported weight and typical proportions for the cut, so treat it as a close estimate.
The story
When the engagement was announced in July 2018, jeweller Jack Solow told People that Justin Bieber wanted a stone that would “gracefully accentuate” Hailey’s hands, and chose an oval “exceptional in its length and grace”.
The ring helped make the elongated oval the defining engagement ring shape of the next few years. In May 2024 she began wearing a new, larger-looking oval solitaire by Lorraine Schwartz. Reports called it 18 carats; she said it was “only one carat bigger. It’s just elongated.”
What it means for you: her own words make the point well. A longer oval looks much bigger on the hand without weighing much more. Ask about the length-to-width ratio, not just the carat weight.
