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 central cushion composite made from lab-grown diamonds, this ring uses a cluster construction to build an expansive top profile. Four sturdy prongs hold the head in place over an open basket gallery, allowing light access through the open framework underneath. Architectural cathedral shoulders rise upward from the band, framing the main setting and adding vertical presence on the finger. The lower band transitions into a traditional round shank with a brilliant high-polish finish that feels smooth against adjacent fingers. Without accent stones on the band, the focus remains entirely on the cushion head and the clean lines of the setting architecture. Choose between yellow gold, rose gold, white gold, silver, or platinum to suit your personal style preferences.
