Weights weren’t released; estimates range from 2 to 3 carats per stone.

How big is it, really?

1ct round · 6.4mm3ct diamond (with an emerald) · 12.3 × 7.9mm

From above, it covers roughly 2.4× 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

Why this ring gets talked about

Machine Gun Kelly proposed in January 2022 with a ring designed with London jeweller Stephen Webster. The emerald is Fox’s birthstone (May) and the diamond is his (April). According to National Jeweler, the emerald is untreated and from Colombia.

The two halves sit on separate bands that are drawn together by magnets hidden in the gold. Webster described them as “two rings which, by the use of magnets buried within the gold, are attracted to each other.”

What it means for you: toi et moi rings are an easy way to make a ring personal, often with two birthstones. If one stone is softer than diamond, like emerald, choose a setting that protects it, and see our emerald guide before you decide.
