About this diamond

A 1.5 carat Round I SI1 HRD certified diamond, this stone combines an Excellent cut with Excellent polish and Excellent symmetry. Its character begins with the round outline: a balanced, circular shape that distributes brilliance around the centre rather than directing the eye along an elongated axis. Here, the 56% table and 63.4% depth give that familiar shape a specific proportion profile, pairing a relatively compact central facet with a deeper overall body. These measurements deserve attention alongside the Excellent cut grade. Measuring 7.20 x 7.25 x 4.58 mm, this round diamond has a near-equal length and width, with a ratio of approximately 1.01. That small difference supports a visually circular outline, while the face-up diameter averages about 7.23 mm. For a 1.5 carat solitaire, that is the visible footprint to consider, rather than carat weight alone. The 63.4% depth sits towards the deeper end of common round brilliant proportions, meaning some of the stone’s weight is carried vertically rather than contributing to its face-up spread. The 56% table provides a relatively compact window into the diamond, leaving more of the face-up surface to the surrounding crown facets than a larger table would. In a round brilliant, that relationship contributes to the balance between white-light brightness and coloured flashes, although the precise effect also depends on the facet angles. HRD’s Excellent cut grade is therefore important context for these proportions. Excellent polish supports clean light reflection at the facet surfaces, while Excellent symmetry indicates precise facet alignment, complementing the round outline and its organised pattern of reflections. At 1.5 carat, I colour places this stone within the near-colourless range, with a subtle warmth that may be more apparent from the side or against a very white setting. Its round brilliant facet pattern and Excellent cut can make that warmth less prominent face-up. SI1 clarity means inclusions are noticeable to a trained grader under 10× magnification; whether they are visible without magnification depends on their individual characteristics. Together, I colour and SI1 clarity describe a diamond whose appeal rests on the interaction of its substantial size, round shape and light performance. With None fluorescence, this diamond has no fluorescence response recorded in its grading, so that characteristic does not add a fluorescent influence to its appearance under ultraviolet-rich lighting. The HRD report documents its carat weight, colour, clarity and cut, together with the stated finish and proportions. For someone considering an HRD certified Round diamond of 1.5 carat with I colour and SI1 clarity, its defining details are the near-circular 7.20 x 7.25 mm outline, compact table and deeper profile.
