About this diamond

Balance defines this one-carat round. The GIA-certified 1 carat Round G SI2 diamond brings together a familiar size milestone, near-colourless appearance and a clarity grade that makes inclusion visibility an important part of the choice. Its combination is considered rather than uniformly high-graded: G colour supports a bright, white impression, while SI2 clarity places more emphasis on understanding the individual stone than on seeking a nearly inclusion-free grade. At 6.33 x 6.37 x 3.98 mm, this 1 carat round diamond has an average face-up diameter of approximately 6.35 mm. The difference between its two diameter measurements is just 0.04 mm, giving it closely matched outlines across those measured directions. For a 1 carat solitaire ring, that diameter provides a recognisable presence without an oversized footprint. Its weight and dimensions work together to describe both how much diamond is present and how much of it is seen from above. The 62.6% depth sits towards the deeper side of commonly favoured round-brilliant proportions, while the 54% table is relatively small. Together, they describe a stone with a modest central facet and appreciable depth beneath the face-up outline, rather than proportions directed primarily towards maximum spread. A smaller table can support the balance of coloured fire and white-light return, although the complete facet geometry governs the result. Here, the GIA Very Good cut grade provides the broader assessment of how those proportions perform together. G colour is in the near-colourless range, making this grade a useful counterpart to the visible size of a 1 carat diamond. Face-up, it will generally read as white, with subtle warmth more readily distinguished in controlled comparison with higher colour grades. SI2 means Slightly Included 2: inclusions are readily noticeable to a trained grader under 10× magnification and may be visible without magnification. Whether this particular stone appears eye-clean requires direct assessment; the grade alone does not establish that. Very Good polish indicates a well-finished facet surface, supporting light transmission and reflection without making surface finish the dominant concern. Good symmetry is a more modest assessment of facet alignment and arrangement, distinct from the closely matched diameter measurements. Alongside the Very Good cut grade, these details establish a balanced but not top-tier finish profile. None fluorescence means no fluorescence was recorded under the grading conditions, so this stone has no reported fluorescent response to factor into its G colour assessment. GIA certification covers this diamond’s stated carat weight, colour, clarity, cut and finishing grades, with proportions and fluorescence also documented. For a buyer seeking G colour and SI2 clarity in a GIA-certified 1 carat round diamond, this stone suits a preference for near-colourless appearance and a measured face-up presence, with clarity as a deliberate consideration.
