About this diamond

A bright, near-colourless impression and a rounded outline are the first visual qualities to consider in this GIA-certified 1 carat Round E SI2 diamond. Its E colour sits within the colourless range, while its measurements of 6.27 x 6.36 x 4.02 mm give that appearance a concrete scale. The GIA grading provides a documented reference for its carat weight, colour, clarity and cut, allowing you to connect what attracts the eye with clearly stated characteristics. The proportions are particularly useful when assessing this 1 carat round diamond. A depth of 63.6% is relatively deep for a round brilliant, meaning some of its weight is carried vertically rather than contributing to face-up diameter. Its 56% table is comparatively restrained, leaving room for the surrounding crown facets rather than presenting an especially broad central window. Together, these figures describe a stone whose full-carat weight should be considered alongside its actual spread, not used alone to predict its size on the hand. Across the face, the 6.27 mm and 6.36 mm measurements produce a length-to-width ratio of approximately 1.01, consistent with a closely rounded outline. For a 1 carat solitaire ring, this means a face-up width of roughly 6.3 mm before the setting is added. The Very Good symmetry grade addresses the alignment and consistency of the facets, complementing that outline. It is a separate assessment from the dimensions: both are useful, but they describe different aspects of the diamond. The Very Good cut grade places the proportions within GIA’s overall assessment of round brilliant cut quality. It should not be confused with an Excellent cut designation, nor interpreted from the table and depth alone. Good polish describes the quality of the facet surfaces, while Very Good symmetry describes their arrangement. Read together, these three grades offer a more specific account of the finish and optical design than the simple description of a round diamond. E colour and SI2 clarity create a distinct pairing at 1 carat: a high colour grade alongside inclusions that are readily noticeable to a skilled grader under 10× magnification. SI2 does not establish whether those inclusions are visible without magnification; that is the one visibility question worth verifying for this stone. Medium fluorescence records a moderate response to ultraviolet light, not a constant glow in everyday surroundings, and should be considered separately from its colourless E grade. For a buyer seeking an E colour, SI2 clarity, 1 carat round diamond certified by GIA, the appeal lies in having these characteristics clearly distinguished. At Seha Diamond, we can help translate its approximately 6.3 mm face-up dimensions into a finished piece, considering the setting’s proportions so the documented stone and the jewellery design work together.
