Lucky D Signature — Premium Laboratory-Grown Diamonds

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.

A note on clarity

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.

Where Lucky D Signature stands

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.

Everyday lab-grown
  • 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.
Lucky D Signature
  • 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.
Natural diamond of the same specification
  • 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.

VS clarity — frequently asked

Why VS. Whether VS2. And how to choose within VS.

Straightforward answers on the clarity threshold behind every Lucky D Signature diamond.

VS (Very Slightly Included) means any inclusions are minor and typically invisible to the unaided eye. It is the calm, confident line where the diamond looks completely clean face-up, holds light beautifully, and still lets you own a meaningfully larger, more expressive stone. Going below VS starts to risk visible characteristics; going above VS (VVS / IF) mainly buys a grade on paper that you cannot see. VS is where honest beauty and honest value meet.
