An impressive and beautifully crafted solid platinum engagement ring featuring a substantial 3.53 carat IGI-certified laboratory-grown radiant-cut diamond, graded G colour and VS1 clarity, with Excellent polish and Excellent symmetry.
The centre diamond features a cut-cornered rectangular modified brilliant cut, more commonly known as a radiant cut, combining the elegant rectangular outline of an emerald cut with the lively faceting and brilliance associated with brilliant-cut diamonds.
The diamond is securely mounted in a classic four-claw platinum setting, complemented by distinctive knife-edge shoulders and a beautifully polished shank. The simplicity of the solitaire design places the emphasis entirely on the substantial centre stone.
Combining classic craftsmanship with an impressive diamond size and desirable grading specifications, this ring makes an elegant choice for an engagement ring or special occasion.
The centrepiece of this ring is a remarkable 3.53 carat rectangular radiant-cut laboratory-grown diamond, measuring approximately 9.97 × 7.81 × 5.18 mm.
Radiant-cut diamonds are particularly admired for their distinctive combination of geometric elegance and brilliant faceting. The rectangular outline features carefully cut corners, while the modified brilliant facet arrangement produces numerous flashes of white light and colour.
The diamond's elongated proportions create an elegant appearance on the finger, offering substantial visual presence without the need for additional accent stones.
Independently graded by the International Gemological Institute (IGI), the diamond has received a G colour grade, placing it within the highly desirable near-colourless range.
Its VS1 clarity grade (Very Slightly Included) indicates minor inclusions that are difficult for a trained grader to observe under 10× magnification.
The diamond has also received Excellent grades for both polish and symmetry, reflecting the quality of its finishing and facet alignment.

The diamond bears a laser inscription corresponding to its IGI identification report number, allowing its identity to be cross-referenced with the accompanying grading documentation.
The diamond is set within a classic solitaire mounting crafted entirely from solid platinum.
The custom-style construction features a central four-claw tapered rectangular gallery setting, designed to accommodate the elongated proportions of the substantial radiant-cut diamond.
The setting features a solid underside and is positioned between distinctive knife-edge shoulders, which introduce an attractive architectural detail to an otherwise understated solitaire design.
The knife-edge shoulders create a subtle ridge along the upper profile of the ring, providing visual definition while drawing the eye toward the centre diamond.
These shoulders transition into a smooth, rounded rectangular shank with a high-polished finish.
The platinum band measures approximately 2.08 mm wide at the upper shoulders, gradually widening to approximately 2.16 mm at the base of the shank.
The ring has been wax cast, hand assembled, and finished, with attention given to the smooth integration of the shoulders, setting, and band.
Platinum is an especially desirable metal for fine engagement rings, appreciated for its naturally white colour, density, durability, and resistance to tarnishing.
Its understated appearance provides an excellent complement to the diamond's near-colourless G grading.

First introduced in the late 1970s, the radiant cut has become a popular choice for those seeking a diamond that combines traditional brilliance with a more contemporary geometric silhouette.
Unlike the broad, linear step facets of an emerald cut, radiant-cut diamonds feature a modified brilliant facet pattern designed to create a lively display of scintillation and reflected light.
The cut corners soften the rectangular outline, while the elongated shape offers an elegant appearance when worn on the finger.
With measurements of approximately 9.97 × 7.81 mm, the diamond offers a substantial face-up presence, making it particularly well suited to a classic solitaire setting.
The simplicity of the platinum mounting allows the natural geometric beauty of the radiant cut to remain the focal point.
The combination of the radiant-cut diamond and knife-edge shoulders gives this ring a particularly attractive balance of traditional and contemporary styling.
The diamond is accompanied by an International Gemological Institute (IGI) Laboratory-Grown Diamond Identification Report, dated May 13, 2026.
IGI Report Number: LG800658297
