About this diamond

A round outline and a gently warm near-colourless grade distinguish this 1.2 carat Round H SI1 HRD certified diamond, with an Excellent cut that helps bring its face-up brightness into focus. H colour sits within the near-colourless range: viewed from above, this stone can present a predominantly white appearance, while a subtle warmth may be more apparent from the side. Its appeal lies in that balance between a bright round brilliant presentation and a colour grade that works comfortably with different metal tones. For a 1.2 carat solitaire in yellow or rose gold, the H colour offers a sympathetic pairing with the warmer metal. A white-metal head can provide a lighter frame around the diamond while retaining a warm-toned band. Platinum or white gold creates a cooler contrast, against which the stone’s slight body colour may be easier to distinguish. In a halo or three-stone setting, choosing accompanying diamonds close to H colour helps maintain a coherent appearance rather than drawing attention to differences between adjacent stones. The 57% table gives this round diamond a moderate central facet rather than an especially broad, open top. Combined with the Excellent cut grade, it supports a proportion profile intended to balance brightness with coloured flashes of fire. That light return matters to the H colour presentation: a lively face-up view can make subtle body colour less prominent than it appears in profile. The 62.9% depth is towards the deeper side of commonly favoured round brilliant proportions, so some of the 1.2 carat weight sits vertically rather than contributing to diameter. Measurements of 6.71 x 6.76 x 4.25 mm translate into an average face-up diameter of approximately 6.74 mm. The small difference between the two width measurements gives a length-to-width ratio of about 1.01, consistent with a closely rounded outline. For a 1.2 carat diamond ring, these dimensions describe the visible footprint more usefully than weight alone. An open-sided setting would reveal more of the 4.25 mm profile, while a bezel would introduce a continuous metal border around the H-colour stone. SI1 clarity means inclusions are noticeable to a trained grader under 10× magnification; it does not automatically mean they are visible without magnification. At this 1.2 carat size, their individual visibility is worth asking about. Excellent polish and Excellent symmetry complement the cut grade through well-finished facet surfaces and precise facet alignment. None fluorescence means no fluorescence was recorded under grading conditions, so there is no reported fluorescent response to consider alongside the H colour. HRD certification provides laboratory assessment of this diamond’s carat weight, colour, clarity and cut, together with its finish grades. For buyers seeking an HRD certified H colour, SI1 clarity round diamond of 1.2 carat, the combination offers a clear basis for discussing both appearance and setting.
