DETAILS

DESCRIPTION

JosĂ©phine’s Diadem centers on a marquise fantasy-cut blue lab-grown sapphire, a gem whose dreamlike facets catch the light in shifting waves of ocean, twilight, and deep royal blue. The vintage setting rises around it like an imperial crown, each engraved curve and delicate prong echoing the diadems worn by empresses of old. Inspired by JosĂ©phine, the empress who turned a garden into a court and a coronation into legend, this ring carries the quiet grandeur of a woman who shaped an empire through grace. The marquise silhouette lengthens the hand like a royal scepter, while the fantasy cut ensures no two stones are faceted alike, making each ring its own private crown.

Wearing it, you carry the hush of a French court and the promise of a love that is both regal and enduring. The blue sapphire’s glow moves with every turn of the hand, revealing hidden depths of sapphire that a traditional cut would never show. Its vintage diadem design does not merely decorate but crowns—an embrace that holds what is precious without hiding its light. JosĂ©phine’s Diadem with a marquise fantasy-cut blue sapphire and vintage setting is an engagement ring for a love that stays sovereign, radiant, and forever rooted—always faithful, always home.

  • Material: 10K/14K/18K Gold, 950 Platinum
  • Main Stone: Blue Lab-Grown Sapphire, Marquise Fantasy Cut
  • Accent Stone: Moissanite
  • Band Width: 1.5mm
  • Band Fit: Comfort Fit

*You may select any center stone of your choice; we will craft the setting accordingly. Should you need assistance with selection, feel free to message us.

Amazing ring - slightly different colour

Amazing ring, my partner absolutely loves it. The detail on the leaves around the ring are perfect, only thing holding it back from a 5 star is the green colour was lighter in person compared to the picture, was expecting a bit more of a forest green
