About this diamond

A 1.51 carat Round F SI2 HRD certified diamond, this stone combines a colourless grade with a clarity grade that deserves particular attention at its size. For everyday wear, that pairing means a bright, neutral colour foundation without the higher clarity designation of a less included stone. Its Very Good cut, Excellent polish and Excellent symmetry complete a profile whose appeal rests on balancing colour, visible presence and the way its proportions handle light. In daylight, the F colour grade places this 1.51 carat diamond firmly within the colourless range, keeping body colour from becoming a defining feature of its appearance. None fluorescence means no fluorescence was observed under the grading conditions; there is no fluorescent response to influence its appearance in ultraviolet-rich light. Together, F colour and None fluorescence offer a straightforward colour profile for a diamond worn between indoor spaces and outdoor daylight, whether set in white metal or against the warmer contrast of yellow gold. The measurements of 7.14 x 7.22 x 4.61 mm give the round outline an approximately 7.18 mm average diameter, with only a small difference between its two face-up dimensions. Its 64.2% depth is relatively deep for a round brilliant, so some of the 1.51 carat weight sits vertically rather than contributing to visible width. For a 1.51 carat solitaire ring, that means a substantial centre stone, but not one whose proportions prioritise maximum spread. The 56% table is comparatively moderate, balancing the central table with the surrounding crown facets rather than presenting an especially broad central window. Under evening lighting, the Very Good cut grade is relevant to the balance of brightness, coloured flashes and contrast. The 56% table and deeper 64.2% profile must be understood together, rather than treating either percentage as a promise of sparkle. Excellent polish supports clean light passage at the facet surfaces, while Excellent symmetry reflects precise facet alignment. These strong finish grades complement the Very Good cut, although they do not turn it into an Excellent-cut diamond. For daily wear, the round shape avoids the exposed points found on some other outlines, making it practical to protect within a well-designed setting. At 1.51 carat, SI2 clarity indicates inclusions readily visible under 10x magnification; whether they are noticeable without magnification depends on their individual characteristics. F colour does not conceal those clarity features. HRD certification provides laboratory grading of the diamond’s weight, colour, clarity and cut quality, giving these specifications a defined reference. For someone seeking an HRD certified round diamond in F colour and SI2 clarity at 1.51 carat, this stone suits an everyday ring where a colourless appearance, a protectable rounded outline and excellent finishing matter more than maximum face-up spread or a higher clarity grade.
