About this diamond

At 1.51 carat, with measurements of 8.72 x 6.30 x 4.13 mm, this HRD-certified 1.51 carat oval J SI1 diamond presents an elongated outline with a length-to-width ratio of approximately 1.38. That ratio gives it a balanced oval silhouette rather than a markedly slender one, while its 8.72 mm length creates a substantial presence along the finger. For a 1.51 carat solitaire, these dimensions matter as much as weight: they describe the visible footprint around which its flashes of brilliance and fire will play. Its light performance begins with the relationship between a 60% table and 65.6% depth. The table forms a moderately sized central window, leaving room around it for crown facets that contribute to coloured flashes as the diamond moves. The depth is on the deeper side for an oval, placing a greater share of the weight below the face-up outline than a shallower stone of comparable weight. These proportions therefore balance a generous central viewing area with appreciable depth; they should not be mistaken for a guarantee of brightness, because an oval’s individual facet angles also govern how light returns. Excellent polish and Excellent symmetry bring an important level of finish to those proportions. Excellent polish indicates very minor surface irregularities, helping the facets transmit and reflect light without conspicuous disruption from polishing marks. Excellent symmetry describes the precision of facet alignment and shape, supporting an orderly pattern of reflections across the elongated outline. Together, these grades complement the 60% table by giving its central and surrounding facets a carefully finished structure. They are finish grades, rather than an overall cut grade, but remain meaningful strengths in assessing this oval diamond. J colour places this stone within the near-colourless range, with a gentle warmth that may be more noticeable in a 1.51 carat oval than in a smaller diamond. Its brilliant-style faceting introduces changing reflections that can make that warmth less prominent face-up, while a yellow-gold setting can make it feel harmonious. None fluorescence means there is no reported fluorescent response to ultraviolet light, so fluorescence is not a factor in its colour presentation. SI1, or Slightly Included 1, indicates inclusions readily visible under 10× magnification; whether they are noticeable unaided, and how the oval’s central contrast appears, requires assessment of the actual stone. HRD certification provides laboratory assessment of the diamond’s stated weight, colour and clarity, alongside its proportions and finish. Here, the combination is distinctive: a moderately elongated footprint, deeper proportions, near-colourless warmth and Excellent finish on both counts. Seha Diamond’s J colour, SI1 clarity, 1.51 carat oval diamond certified by HRD is suited to a buyer seeking a substantial oval solitaire who prioritises precise finish and lively faceting while welcoming a warmer colour character.
