An elegant platinum diamond solitaire engagement ring featuring a 1.51 carat GIA-certified natural round brilliant-cut diamond, graded F colour and I1 clarity, with Excellent cut, polish, and symmetry.
Custom handmade in solid platinum, this classic engagement ring features a substantial four-claw setting, an open double-gallery design, and a beautifully polished tapered shank. The minimalist solitaire design places emphasis on the central diamond, allowing light to enter through the open setting while maintaining a timeless, refined appearance.
The centre diamond measures approximately 7.30 × 7.33 × 4.58 mm and has been graded by the Gemological Institute of America (GIA). Its F colour classification places it within the colourless range, while its Excellent cut grade, Excellent polish, and Excellent symmetry reflect the precision of its cutting and finishing.

The raised rectangular shoulders integrate smoothly into the setting, creating a balanced transition between the diamond and the platinum shank.
The band features a polished exterior with a gently curved comfort-fit interior, providing a smooth fit against the finger. The use of platinum offers a naturally white finish, excellent durability, and a substantial feel.
The simplicity of the solitaire design makes this ring suitable as an engagement ring or an elegant statement piece, while its classic proportions allow it to complement a variety of wedding band styles.
