Carat is a measure of weight, while the millimetre dimensions tell you more about how large the diamond faces up and how the setting must be engineered. This stone measures 9.91 × 5.35 × 3.14 mm, so those actual dimensions can guide claw position, halo spacing, bezel size and setting clearances. At one carat or above, it can be treated as a prominent centre stone for a solitaire, halo, cathedral, three-stone or statement pendant design.

D sits in the colourless D–F range, associated with a crisp, neutral-to-colourless diamond appearance. White metals can maintain that cool presentation, while yellow or rose gold can create deliberate contrast.

SI2 sits in the Slightly Included clarity range. Whether inclusions are visible without magnification depends on their size, relief, type and location as well as the diamond’s shape, so image/video or gemologist review is particularly useful. Ask our Graduate Gemologist (GIA) if you would like an opinion on whether this exact diamond appears eye-clean in normal viewing.

For a Marquise diamond, appearance should not be reduced to a Round Brilliant cut scale. Outline, facet pattern, contrast, length-to-width ratio, polish, symmetry and image/video assessment are important parts of the selection. Recorded finish: Polish EX · Symmetry EX.
