About this diamond

At 1.12 carat, with measurements of 6.58 x 6.60 x 4.13 mm, this round diamond presents a face-up diameter close to 6.6 mm. For someone seeking a GIA certified 1.12 carat round I SI1 diamond, those dimensions put the clarity grade into useful perspective: the stone has enough presence for its appearance to matter, while SI1 describes characteristics assessed under magnification rather than a fixed level of naked-eye visibility. SI1 means Slightly Included 1: a skilled grader can see inclusions at 10x magnification. In a round diamond of this size, that does not automatically mean they will be apparent without a loupe. Some SI1 diamonds appear clean to the unaided eye, but the grade alone cannot establish whether this particular stone does. The distinction is important for a 1.12 carat solitaire, where attention naturally settles on the diamond rather than on surrounding stones. Its Excellent cut grade adds another dimension to that clarity discussion. A well-cut round brilliant uses changing reflections and flashes of light to create a lively face-up appearance, which can make small internal features less conspicuous during everyday wear. Here, Excellent polish supports clean facet surfaces, while Excellent symmetry describes the precision of facet alignment. Together, these three Excellent grades support the optical presentation of this SI1 round diamond without changing what its clarity grade means under magnification. The 58% table and 62.7% depth place that optical presentation within a specific set of proportions. A 58% table leaves room for the crown facets that contribute to coloured flashes, while the 62.7% depth sits towards the deeper side of commonly encountered round brilliant proportions. Some of the 1.12 carat weight is therefore carried vertically rather than entirely in face-up spread. The closely matched 6.58 and 6.60 mm measurements give it a near-circular outline, with a length-to-width ratio of approximately 1.003. I colour belongs to the near-colourless range, bringing a subtle degree of warmth rather than the cooler appearance associated with higher colour grades. At this 6.6 mm diameter, the Excellent cut’s light return can help that colour look less apparent face-up than from the side. None fluorescence means no fluorescence was detected under the laboratory’s grading conditions, so there is no blue fluorescent contribution to offset the I colour in ultraviolet-rich light. GIA certification provides an independent assessment of the stated carat weight, colour, clarity, cut, polish, symmetry and fluorescence. For buyers considering an I colour, SI1 clarity round diamond of 1.12 carat certified by GIA, the central balance is clear: magnification-based clarity, near-colourless warmth and Excellent finishing in a defined face-up size.
