Emma Stone's Engagement Ring: Breaking Tradition

When Dave McCary proposed to Emma Stone in 2019, he didn't use a diamond. He used a Pearl. The ring, designed by Japanese jeweler Kataoka, sparked a massive interest in alternative engagement rings.

  • Center Stone: An 8mm untreated Akoya pearl.

Should You Get a Pearl Engagement Ring?

Emma Stone can afford to replace her ring if it breaks. Can you?

Warning: Pearls are Soft

Pearls are a 2.5-4.5 on the Mohs hardness scale. Diamonds are a 10. Pearls can be scratched by dust. They are sensitive to acids (perfume, vinegar, lemon juice).

Our Verdict: While beautiful, pearls are not suitable for daily, forever wear unless you are extremely careful. If you love the look, wear it as a dress ring, not an everyday engagement ring.
