About this diamond

For a buyer seeking a substantial round solitaire with clearly documented characteristics, the GIA-certified 1.5 carat Round E SI2 diamond offers a precise starting point. Its appeal rests on a specific combination: colourless E colour, SI2 clarity, a Very Good cut and Strong fluorescence. GIA grading provides an independent assessment of these characteristics, giving you a framework for understanding the stone rather than relying on broad descriptions of brilliance or beauty. The measurements, 7.17 x 7.22 x 4.58 mm, make that framework tangible. Across the top, this round diamond measures approximately 7.2 mm, with just 0.05 mm separating its two recorded diameters. That near-equal outline suits a centred solitaire design. Its 63.6% depth is relatively deep for a round brilliant, meaning more of its 1.5 carat weight sits vertically than in a shallower stone of the same weight. The diameter therefore gives a more useful sense of its visible size than carat weight alone. A 57% table brings a moderate central facet to those deeper proportions. For this stone, that combination should be read alongside the GIA Very Good cut grade, rather than treated as a promise based on table size alone. The cut assessment considers how the round brilliant’s proportions work together, including its light performance. Here, the documented result is Very Good rather than Excellent: a meaningful distinction for a buyer comparing GIA-certified round diamonds with similar weight, colour and clarity. Excellent polish and Very Good symmetry add further detail to that cut assessment. Excellent polish indicates a high standard of facet-surface finish, supporting clear passage and reflection of light. Very Good symmetry describes the precision of facet alignment and arrangement. Together, these grades distinguish surface finishing from geometric precision; the Excellent polish does not override either the Very Good symmetry or the overall Very Good cut grade. E colour places this 1.5 carat diamond within the colourless range, while SI2 clarity indicates inclusions readily noticeable to a skilled grader at 10× magnification. At this size, whether those inclusions are visible without magnification is worth checking for this particular stone. Strong fluorescence records a pronounced response to ultraviolet light, not a lower colour grade; it may influence appearance in UV-rich conditions, whereas its effect is less relevant under lighting with little ultraviolet content. For an E colour, SI2 clarity, 1.5 carat round diamond certified by GIA, confidence comes from connecting the documented grades with its approximately 7.2 mm face-up dimensions. Seha Diamond can help translate that scale into a finished piece, considering setting proportions and a suitable mount for the 4.58 mm depth, whether you envisage a focused solitaire ring or a design with surrounding diamonds.
