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 |

Crisp geometric lines meet fluid detail through the combination of a sharp princess lab-grown diamond and a split shank band. The open basket setting elevates the center stone above a polished round surface, making it an easy choice for everyday wear across various metal options.
Built around a clean geometric shape, this ring features a princess lab-grown diamond held at four corners by dedicated prongs. The open basket gallery creates space beneath the stone, maximizing light entrance from every side. Moving downward, the shoulders split into a distinct open space before tapering into a rounded, high polish band. This solitaire structure avoids accent stones entirely, focusing all attention on the single lab-grown diamond. The round profile of the band ensures comfort during long periods of wear, fitting easily against the finger. Customization is offered across five metal choices, including yellow gold, rose gold, white gold, silver, and platinum. Each material accentuates the crisp edges of the princess cut while maintaining a balanced profile on the hand.
