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 |

Centered on a single round lab-grown diamond, this ring celebrates traditional solitaire architecture with crisp detailing. Four slender prongs secure the stone inside a low-profile basket gallery, allowing light to reach the gem while keeping it safe during daily wear. Below the setting, straight shoulders align directly with the center mount, creating a balanced silhouette that transitions smoothly into a rounded shank. The band receives a high-polish finish that reflects light around the entire circumference. Because there are no accent stones, the design emphasizes pure symmetry and clean lines. Customization options allow you to tailor the final piece to your aesthetic preferences. Choose between yellow gold, rose gold, white gold, silver, or platinum to pair with the central round lab-grown diamond. Each metal choice highlights the high-polish finish and simple geometry in a distinct way.
