Laboratory-grown diamonds have fundamentally changed the economics of the diamond industry. As prices fall and availability rises, the central question for jewellers and brands is no longer about sourcing — it is about meaning. How do you maintain perceived value when the physical product has become a commodity?

Article Summary

  • Lab-grown diamonds commoditised the stone. Price pressure alone cannot differentiate a jeweller or brand — the raw material is now identical regardless of who sells it.
  • Personalisation moves value inside the stone. A permanent sub-surface mark creates a product that is inherently unique, regardless of who else sources the same raw diamond.
  • Diamond ID makes this a B2B process — not a capital investment. No equipment to buy. Test on a lab-grown sample first. Add to your offer when ready.

This article is for you if:

  • You sell or design jewellery and feel pricing pressure from online or chain retailers.
  • You represent a brand looking for a defensible point of difference in the lab-grown segment.
  • You want to understand how personalisation technology works at the material level — no engineering background needed.

Why lab-grown diamonds changed everything

Until recently, a diamond’s story was simple: mined from the earth, certified, sold. The certificate was the proof; the rarity was the value. That model worked because diamonds were genuinely scarce — and that scarcity was credible.

Laboratory-grown diamonds broke that logic. Chemically and physically identical to mined stones, they introduced something the traditional market never had to account for: abundance. By 2024, lab-grown diamonds had captured nearly 20% of the global diamond jewellery market by volume¹, and prices continued to fall as production scaled.

For the consumer, this is welcome news. For businesses selling diamonds, it raises a harder question: if the stone itself is no longer rare, what justifies a premium price? And if the answer is “the brand” or “the craftsmanship” — how does any of that become visible inside the stone itself?

What personalisation adds to a stone

A laser mark inside a diamond is not decoration. It is information — permanent, unalterable, and unique. Unlike a surface engraving on a ring band, a sub-surface inscription cannot be removed without destroying the stone itself.

This changes what a stone can carry. A diamond can now hold a name, a date, a handwritten signature, a family crest — made visible with a loupe or under particular light. The stone stops being a commodity and becomes a vessel for meaning.

“The stone stops being a commodity. It becomes a vessel for meaning — specific to one person, one moment, one relationship.”

— Dr. M. Kołda, Diamond ID technology brief

² The inscription uses a femtosecond laser at 10⁻¹⁵ s pulse duration, creating structural changes inside the diamond lattice without surface contact. Nanores internal research documentation, 2023.

How the technology works — without a microscope

The process uses a focused ion beam (FIB) to create a controlled structural change within the diamond’s carbon lattice. Unlike surface-level laser engraving, the modification occurs below the surface — inside the stone, at the nanometre scale. The result is a mark that is permanently part of the diamond’s structure.

For the end consumer, this is visible with a standard 10× loupe — the kind any jeweller carries. No special equipment, no smartphone, no additional reading device. The inscription is there, readable, durable, and identical to the diamond itself in permanence.

What this means for jewellers and brands

The commodity pressure on diamonds is not going away. The question for jewellers and brands is not whether to adapt, but what form that adaptation takes. Price competition is a race with no sustainable finish line — and increasingly, it is a race being run against entities with far greater scale and distribution than any boutique workshop.

Personalisation offers a different answer. Not “we sell better diamonds” — but “we create something that cannot be replicated, compared, or found anywhere else.” That shift changes what the customer is buying: not a commodity, but a unique physical object with a specific meaning. And that difference lives inside the stone — not on a certificate, not in a shopping bag.

Traditional market approach vs. Diamond ID

CriterionTraditional approachDiamond ID approach
Stone identityAnonymous — any retailer can source the same stoneUnique — inscription is inside the stone, non-transferable
Comparison basisPrice, certificate, visual gradeStory, meaning, origin — physically embedded
Perceived rarityDependent on mining certificationInherent — the inscription creates uniqueness
Brand protectionExternal — packaging and brandingInternal — the stone carries the brand signature
After-sale connectionWeak — stone untraceable after saleStrong — identification persists for the stone’s lifetime
Price negotiationHigh — direct comparison with competitorsLow — no equivalent product to compare against
Setup (B2B)None — sell existing inventorySample test + onboarding (weeks, not months)

Frequently asked questions

Is the inscription visible without special equipment?

Yes — a standard 10× loupe (the kind any jeweller carries) is sufficient. The mark is visible under the loupe and subtle enough not to distract from the stone in normal light.

What happens if the stone is re-cut or re-polished?

A sub-surface inscription survives most surface-level re-polishing. Significant re-cutting could affect it — comparable to any other structural feature of the stone.

Do I need to invest in equipment?

No. The inscription is processed centrally. You send the stone; it returns with the inscription complete. No capital expenditure required to begin testing.

Is this compatible with lab-grown and natural diamonds?

Yes. For initial testing, we recommend a lab-grown stone equivalent in size to your typical commission pieces — minimal risk, identical result to natural.

What does the onboarding process look like?

We start with a sample test on a stone you provide. From test to first client-ready piece: typically two to four weeks. We support the first client conversation if needed.
