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 |

Centering on a round lab-grown diamond, this ring highlights structural balance and clean form. Four precise prongs hold the stone securely, while the elevated cathedral setting introduces height and prominence on the finger. Tapered shoulders narrow softly as they meet the center structure, drawing attention directly to the lab-grown diamond. Below the main setting, an open gallery allows light to pass through the sides, enhancing visibility from profile view. The rounded shank rests smoothly against neighboring fingers, finished with a mirror-like high polish. Offered without accent stones, the design focuses entirely on the central stone and its architectural frame. Choose from yellow gold, rose gold, white gold, silver, or platinum to suit personal preference.

FAQs
How does the cathedral setting affect the ring's overall height?
The cathedral setting arches upward, raising the round lab-grown diamond slightly higher than a traditional low-profile basket setting.
What is the advantage of an open gallery design?
An open gallery leaves the space beneath the center stone open, allowing light to enter and making the ring easy to clean.
Does the tapered shoulder design change how the ring feels on the finger?
The tapered shoulders reduce metal bulk near the top, giving the ring a balanced feel while emphasizing the center stone.
How do I care for the high polish band?
Wipe the polished metal regularly with a soft lint-free cloth and clean gently using warm soapy water.
Is this solitaire ring suitable for everyday wear?
Yes, the round shank and sturdy four-prong setting are designed to offer secure, comfortable wear for daily use.
