Our Selection Standard
Selected for colourlessness, cutting precision, optical symmetry and documented quality.
More Carat. No Lower Standard. Not all laboratory-grown diamonds are equal — growth method, colour, clarity, cut, proportions, polish, symmetry, fluorescence, optical precision, certification and craftsmanship can all affect the final result.

The minimum approved clarity for the Lucky D Signature collection is VS (VS2 or better). Each product page displays the specific clarity grade shown on the diamond’s IGI report.
The diamond you always wanted to wear — finally at the size you always wanted to wear it.
A D-colour, VS-clarity, top-cut round brilliant used to be a specification quietly reserved for a small circle of collectors. We did not lower that specification — we simply made it possible to wear it in the carat that actually feels like you. This is not a compromise. This is the exact top specification, worn openly, honestly, and beautifully.
- Sold mainly on carat and price.
- Colour may range across G–J; clarity often SI.
- Cut, polish, symmetry frequently uneven; fluorescence not filtered.
- Report may be from lesser-known labs or omitted altogether.
- Origin disclosure inconsistent; treatments rarely explained.
- Selected for how it looks on your hand, not just the price tag.
- D colour, minimum VS clarity, top cut, Excellent polish & symmetry.
- None fluorescence; Hearts & Arrows where documented.
- Every stone with an IGI Laboratory-Grown Diamond Report + verification link.
- Origin, growth method and any post-growth treatment openly disclosed.
- Final face-up review by Alice before it becomes yours.
- A 2ct D VS Excellent-cut natural diamond sits in a rare and expensive tier.
- Achieving 3ct+ in the same specification becomes extraordinarily scarce.
- Price often reserved for a very small group of buyers.
- Same chemical composition, crystal structure and optical properties as a lab-grown diamond.
- The difference is origin and rarity of geological history — not what the eye sees.
We do not ask you to choose between lab-grown and natural. We ask you to choose the specification, the beauty and the story that belong to you — and to know exactly what you are wearing, and why.
Why VS. Whether VS2. And how to choose within VS.
