About this diamond

For a buyer choosing a solitaire with a clear, balanced presence rather than an oversized outline, a 1.01 carat Round I SI1 GIA certified diamond offers a compelling starting point. Its 6.32 x 6.37 mm face-up measurements give this stone a diameter of approximately 6.35 mm, with an almost circular outline. That footprint suits a ring designed to let one diamond lead, while the Excellent cut grade makes its optical performance an important part of its appeal. The proportions help explain how this 1.01 carat diamond carries its weight. A 62.8% depth sits towards the deeper end of commonly favoured round-brilliant proportions, while the 58% table is moderate rather than unusually broad. Together with the 3.99 mm total depth, these figures describe a stone that balances visible spread with depth below the girdle. For a 1.01 carat solitaire ring, the actual diameter is therefore more useful than carat weight alone when judging how much space the diamond will occupy on the finger. A halo offers a different way to use that approximately 6.35 mm centre. Surrounding diamonds can extend the overall outline without changing the central stone’s measured size, making this round diamond suitable for a buyer who wants a broader ring silhouette. Its I colour belongs to the near-colourless range, where a gentle warmth can become more apparent beside higher-colour accents. Choosing halo stones with that relationship in mind creates a more coherent composition; yellow or rose gold can also make the I colour feel harmonious with the setting. For a pendant, the combination of 1.01 carat weight, Excellent cut and Excellent polish is particularly relevant: the stone has enough diameter to read clearly as a single focal point, with finely finished facet surfaces supporting its light return. Excellent symmetry describes the precision of facet alignment, complementing the cut grade. SI1, or Slightly Included 1, means inclusions are evident under 10× magnification; their visibility without magnification is individual to the stone, so the grade alone does not establish an eye-clean appearance. In a three-stone ring, the 6.32 x 6.37 mm measurements provide a practical centre-stone reference for selecting proportionate side diamonds. For earrings, the same measurements, I colour and SI1 clarity offer useful matching criteria for a companion stone. None fluorescence means no fluorescence was recorded under the grading conditions, so there is no reported fluorescent response to factor into the pairing. GIA’s report documents the colour, clarity, cut, finish and measurements that underpin these comparisons. Whether you favour a solitaire, a halo or a pendant, this GIA certified Round diamond in I colour and SI1 clarity at 1.01 carat gives you a specific scale and proportion profile to design around.
