Momenti Unici began as a dream in the heart of Austin, Texas. Founded by Mariana Rossi—a gifted designer specializing in diamond cutting and metalsmithing, the brand quickly became synonymous with timeless elegance and artisanal craftsmanship.

Mariana believes jewelry should mark life’s most cherished milestones: engagements, weddings, anniversaries, and moments of remembrance.

Each piece is designed to carry grace, meaning, and emotional depth.

From her intimate atelier tucked behind the original storefront, Mariana personally shaped every creation, infusing it with her signature blend of classic beauty and modern refinement.

Her reputation grew organically, fueled by word-of-mouth and a loyal online following drawn to her authenticity, artistry, and devotion to craft.
