Carat size on the finger
Drawn to scale on a size 6 finger (16.5 mm wide). Sizes are approximate face-up measurements.
Carat is weight, not size. A 2.00 ct stone looks about 25–30% wider than a 1.00 ct, not twice as wide. On a slimmer finger the same stone looks bigger.
Diamond colour & clarity
Colour runs from D, with no colour at all, towards a faint yellow. D–F look icy white. G–H look white once set, especially in yellow or rose gold.
Clarity is how many tiny natural marks a diamond has. From VS1 upwards they can't be seen without 10× magnification.
| Grade | What it means |
|---|---|
| FL · IF | Flawless — nothing seen at 10× |
| VVS1 · VVS2 | Very, very slight — very hard to find at 10× |
| VS1 · VS2 | Very slight — eye-clean, minor marks at 10× |
| SI1 · SI2 | Slight — usually eye-clean in smaller stones |
| I1 | Included — marks may be visible to the eye |

Built around a solitary round lab-grown diamond, this ring combines structural detail with a clean focus on the central stone. Four slim prongs grasp the lab-grown diamond, elevating it above an open gallery that admits light from every side. Cathedral shoulders arch upward from the shank, adding architectural height while framing the stone cleanly. The band itself is shaped with a softly curved, round shank that sits comfortably against adjacent fingers. Free from accent stones, the design relies on precise geometry and a mirror-like high polish across the entire metal surface. Buyers can personalize the design by selecting from yellow gold, rose gold, white gold, silver, or platinum. The combination of elevated cathedral proportions and a smooth inner contour creates a piece that feels for daily wear while emphasizing the clarity of the round lab-grown diamond.
