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 |

The clean symmetry of a square princess cut lab-grown diamond pairs with structural cathedral arches to create a refined profile. Wearers will appreciate how the raised trellis setting captures light from every direction while the soft flat shank provides day-long comfort.
Designed around a sharp princess cut lab-grown diamond, this ring gives prominence to the center stone without the addition of accent stones. Four protective prongs grip each corner, grounded by a trellis gallery whose sweeping curves cross underneath the setting. Rising gently from the band, cathedral shoulders elevate the entire center assembly, creating a light-filled profile visible from every angle. The inner and outer band are crafted with a soft flat profile, offering a smooth fit that sits low and balanced on the finger. Finished with a high polish coating, the surface shines in your preferred metal choice, whether yellow gold, rose gold, white gold, silver, or platinum. Every angle highlights structural balance, from the straight edges of the square stone to the arching lines of the cathedral shoulders.
