About this diamond

Clarity deserves a closer look at 1.21 carat. An HRD certified 1.21 carat Princess F SI2 diamond, this stone combines a colourless grade with inclusions that are readily noticeable to a trained grader under 10× magnification. SI2 means Slightly Included 2, but it does not automatically mean visible marks to the naked eye. At this weight, the distinction matters: there is enough face-up area for clarity characteristics to influence how clean the diamond appears. For this princess diamond, the SI2 grade is best understood alongside its 6.02 x 5.84 mm outline and 76% table. That broad central facet provides a substantial window into the stone, making the appearance of inclusions beneath it particularly relevant. The princess cut’s intersecting facets can help break up their visibility elsewhere. Whether this particular SI2 diamond looks eye-clean depends on the inclusions’ size, contrast and position, which the grade alone does not establish. Its measurements give a length-to-width ratio of approximately 1.03, so the outline is close to square, with only a slight difference between the two sides. In a 1.21 carat princess solitaire ring, that means a compact, geometric face rather than a noticeably elongated silhouette. The 4.18 mm depth and 71.6% depth percentage place a meaningful share of the weight below the face-up outline, reminding the buyer that carat weight and visible dimensions describe different aspects of size. The 76% table is broad for a princess cut, while the 71.6% depth is consistent with the deeper architecture often seen in this shape. Together, these figures describe a stone with a generous top facet rather than a small-table profile. They do not independently establish light performance, but they explain why central clarity deserves attention here. Excellent polish supports clean facet surfaces, while Very Good symmetry indicates closely aligned facet geometry, both contributing to an orderly presentation of reflected light. F colour places this 1.21 carat diamond within the colourless range, giving its near-square outline a visually neutral colour foundation. Colour and clarity remain separate considerations: the F grade does not conceal SI2 inclusions, but it keeps body colour from becoming the principal compromise. None fluorescence means no fluorescence was detected during grading, so there is no reported ultraviolet response to factor into the colour assessment. HRD certification provides laboratory grading of the diamond’s weight, colour, clarity and finish. For a buyer seeking a Princess diamond of 1.21 carat with SI2 clarity and F colour, certified by HRD, the central question is how the clarity presents across that broad table. Its colourless grade, near-square dimensions and strong finish make that a focused, practical comparison.
