About this diamond

Brightness and a crisp outline are what the eye is likely to notice first in this 1.01 carat Round E SI1 GIA certified diamond, rather than the small internal details behind its clarity grade. Its Excellent cut supports the light return that gives a round brilliant its lively appearance, while E colour keeps body colour from becoming a prominent part of the impression. At approximately 6.46 mm across, the stone offers a useful balance of visible presence and fine detail. SI1 means Slightly Included 1: clarity characteristics are noticeable to a trained grader under 10× magnification. It does not mean those characteristics will necessarily be obvious without magnification. In a round diamond of this 1.01 carat size, the brilliant facet pattern and changing reflections can make small inclusions less apparent during everyday viewing. Whether this particular stone is eye-clean depends on the characteristics themselves, which the supplied specifications do not describe. The distinction matters: SI1 describes the magnified view, not a guaranteed naked-eye appearance. The E colour grade complements that clarity profile in a specific way. E sits within the colourless range, so this stone combines a very low level of body colour with inclusions that determine its SI1 designation. These are separate qualities: the clarity grade does not make its colour less white, and the colour grade does not erase internal features. For a 1.01 carat solitaire, the result is a colourless centre stone whose clarity deserves attention at the scale at which it will actually be worn. Its 6.44 x 6.48 x 3.91 mm measurements give an almost equal length and width, with a ratio of approximately 1.01. That supports a near-circular face-up outline. The 60.6% depth and 59% table describe a relatively open table paired with a depth that does not suggest excessive weight hidden vertically. Together, these proportions help explain its spread, while the GIA Excellent cut grade provides the broader assessment of how its round brilliant proportions perform. Excellent polish means the facet surfaces have a high-quality finish, supporting clear reflections rather than surface-related interference. Very Good symmetry indicates minor departures in facet alignment or arrangement, yet the overall cut remains Excellent. None fluorescence means no fluorescence was detected under the laboratory’s grading conditions. GIA’s grading covers the stated carat weight, colour, clarity, cut and finish, giving this E colour, SI1 clarity Round diamond of 1.01 carat a documented framework for comparison. For a buyer focused on clarity, the central question is how this SI1 grade presents alongside E colour and Excellent cut at a face-up diameter of about 6.46 mm.
