Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it traces a delicate arc of brilliance that seems to whisper a story of quiet devotion. This three-stone semi-set engagement ring in platinum frames a 10 x 5 mm marquise center with two gently tapering side stones, each carefully nestled in a low-profile setting that balances presence with everyday grace.

Crafted in solid platinum, the band offers a cool, substantial feel against the skin, finished to a satin sheen that softens reflections and invites touch. The prongs curve protectively around the marquise’s pointed ends, securing the stone while maintaining a sleek profile that slips easily beneath gloves or alongside stackable bands.

Each lab-grown diamond is selected for clarity and cut, embodying an ethical choice that reduces environmental impact without compromising on radiance. This ring suits a wearer who appreciates architectural elegance paired with subtle romance—its elongated shape visually lengthening the finger and harmonizing with slender or medium-width hands.

Should you need a custom fit, resizing is available to ensure comfort and longevity. The semi-set design allows you to select a center stone that resonates personally, making the ring uniquely yours.
