Sunlight catches the delicate curve of a 3.5 mm round diamond, its facets whispering quiet brilliance against the soft glow of 18K white gold. This semi-set solitaire invites you to choose a center stone that will become a daily companion, framed by a slender band that balances strength with subtle elegance.

Crafted in Williamsburg, Brooklyn, the band’s smooth finish and low-profile setting ensure comfort for everyday wear, slipping easily beneath a glove or alongside a wedding band. The refined silhouette highlights the diamond’s classic round cut—known for its lively sparkle and timeless appeal—while the white gold’s cool tone enhances its clarity.

Each piece reflects a commitment to ethical jewelry: the center stone is lab-grown, offering a sustainable choice without compromise on brilliance or integrity.

Designed for those who appreciate understated romance and thoughtful craftsmanship, this solitaire suits a range of hand sizes and styles, perfect for stacking or wearing solo. The semi-set format allows you to personalize your ring with a diamond that speaks to your story.
