Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a 5 x 5 mm cushion diamond, its gentle glow framed by two smaller stones that whisper of shared moments. This three-stone semi-set invites you to choose a center stone that balances vintage warmth with modern clarity.

Crafted in cool platinum, the mounting features delicate prongs that cradle each gem securely while maintaining a low profile for everyday wear. The band’s subtle weight and smooth finish reflect careful hand polishing, ensuring comfort and resilience through daily life.

Each diamond is lab-grown, offering a transparent origin story and a smaller environmental footprint without compromising brilliance or purity.

Designed for those who appreciate a ring that layers meaning and style, this setting suits slender to medium finger sizes and pairs effortlessly with stacking bands or a wedding band. Its modest height slips easily beneath gloves or sleeves, making it a practical choice for active hands.

Resizing is available to ensure a precise fit, and the semi-set format allows you to select a center stone that resonates personally, with typical lead times tailored to your custom design journey.
