About this diamond

Light performance starts with proportion and precision. The HRD-certified 1.6 carat Round I SI2 diamond combines an Excellent cut with Excellent polish and Excellent symmetry, placing its cutting quality at the centre of its appeal. For a round brilliant of this weight, those grades matter: they describe the proportions and finish that help light return through the crown rather than escape through the pavilion. Its 62.3% depth and 59% table give that cutting quality a specific profile. The depth sits towards the deeper side of commonly favoured round brilliant proportions, while the table is moderately broad. Together, they offer context for the Excellent cut grade rather than a separate promise of performance. The 59% table provides a broad central window for brightness; coloured fire also depends on how the crown and pavilion facets work together. At 7.43 x 7.45 x 4.64 mm, this round diamond has an average face-up diameter of approximately 7.44 mm. Its length-to-width ratio is almost exactly 1.00, giving it a closely balanced circular outline. The 4.64 mm height accounts for the stated depth, so the 1.6 carat weight is distributed through both diameter and depth. In a 1.6 carat solitaire ring, that diameter provides a substantial centre without relying on an elongated shape for visual reach. Excellent polish and Excellent symmetry support the proportions in different ways. Polish describes the quality of the facet surfaces, helping light enter and leave without unnecessary surface interference. Symmetry concerns facet alignment and consistency, contributing to an orderly pattern of reflections across the round outline. Alongside the Excellent cut grade, these finish grades make precision a defining feature of this stone. HRD certification documents its carat weight, I colour, SI2 clarity, cut, polish and symmetry grades, as well as fluorescence. I colour places this diamond within the near-colourless range, with subtle warmth that can be more noticeable from the side or against very white surroundings. Strong light return can make that warmth less apparent face-up. SI2, or Slightly Included 2, indicates inclusions readily visible under 10x magnification; at 1.6 carat, whether they are visible without magnification deserves individual assessment. Its None fluorescence grade means ultraviolet-induced fluorescence is not a factor in its appearance. For someone seeking an I colour, SI2 clarity Round diamond of 1.6 carat certified by HRD, the distinction here lies in the combination of Excellent cutting and finish with a near-circular 7.44 mm spread. Seha Diamond can help translate those dimensions into a finished piece, selecting a setting that accommodates the 4.64 mm depth and presents the round brilliant’s face-up light pattern clearly.
