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 |

This three-stone ring puts a heart lab-grown diamond at the center of its design. The stones are anchored by five prongs, creating a sturdy architecture that rests within a traditional basket gallery. By elevating the gems, the gallery permits light to pass through while keeping the overall setting low-profile and secure. Moving down to the band, tapered shoulders narrow gently as they meet the setting, creating a visual flow that highlights the central heart shape. The half-round shank delivers a classic curve along the finger, balanced by a smooth high-polish finish that reflects light cleanly. Built without extra accent stones, the design relies strictly on its core trio of lab-grown diamonds for visual impact. You can tailor the final look to your personal preference with choices across yellow gold, rose gold, white gold, silver, or platinum.
