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 side-by-side arrangement of three round lab-grown diamonds creates strong visual symmetry enhanced by the polished metal finish. People choose to wear this ring for its balanced silhouette, secure four-prong basket support, and comfortable round band.
Built around a trio of lab-grown diamonds, this ring highlights three round gems in a balanced three-stone arrangement. A four-prong mechanism anchors each lab-grown diamond securely within a structural basket gallery, allowing light to enter from multiple angles along the sides. The ring transitions gracefully toward the finger through tapered shoulders that narrow as they meet the focal setting. Below, the round shank provides a traditional, comfortable contour designed for everyday wear. Finished in a smooth high polish, the metal surface reflects light evenly across the entire band. With no extra accent stones along the band, the three-stone center remains the sole focal point. Select your preferred metal from yellow gold, rose gold, white gold, silver, or platinum to customize the final look.
