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 |

Arching cathedral shoulders and a hidden bridge accent give this ring a striking architectural silhouette from every perspective. Its smooth inner band and clean solitaire styling make it an effortless option for daily wear.
Architectural grace defines this solitaire ring, anchored by a cushion lab-grown diamond held firmly in a four-prong setting. Cathedral tapered shoulders gently arch upward from the band, guiding the eye directly to the center stone while creating space beneath for a bridge accent gallery. This structural elevation allows light to reach the lab-grown diamond from multiple angles, enhancing its presence on the hand. A soft round shank sits gently against neighboring fingers, providing smooth comfort during everyday wear. The band is polished to a high mirror finish that highlights the clean geometry of the mounting. Free of accent stones, the design places full emphasis on the central gem and its sculpted silhouette. Choose from yellow gold, rose gold, white gold, silver, or platinum to tailor the ring to your personal metal preference.
