03 Technical foundation

The science behind
every stone.

HPHT SYNTHESIS AT THE CONDITIONS
WHERE NATURAL DIAMONDS FORM —
PUBLISHED, MEASURED, VERIFIED.

Pressure5.5 GPa HPHT synthesis chamber — multi-anvil cubic press.

Temperature1,450 °C Crystal growth environment, held stable across the batch.

Carbon purity99.95 %+ Purification threshold before growth begins — spectroscopy gated.

Growth time18–25 days Crystal formation per batch, independent parameter control.

Carbon R&D2003 since Two decades of carbon research; national invention patent granted 2012.

Vial of purified carbon and a lock of hair — memorial diamond source material — **FIG. 03** — SOURCE MATERIAL, PRE-PURIFICATIONHAIR · FUR · FLOWERS · PLANTS

We do not make jewelry. We make diamonds — from carbon in hair, pet fur, flowers, any organic material. Our 2012 invention patent (ZL 201010565778.9) covers the full bio-carbon-to-diamond pipeline, and every batch is purified to 99.95%+ carbon — verified by spectroscopy, not claimed on a datasheet.

The result: a gem-quality lab-grown diamond, chemically and optically identical to mined stone.

Inside our HPHT presses, that carbon crystallizes around a seed over 18–25 days. Stability across the entire growth window is what determines clarity.

04 Industry honesty

Why we say no to ash — and what we do instead.

What a body yields2–3 KG ASH

Usable carbon left in it≈0.3% · 6–9 G

→

VerdictTHE MATH FAILS

Cremation destroys the carbon. The 6–9 grams that remain are carbonate locked inside bone mineral — not extractable feedstock — and 67–91% of even that comes from the cremation furnace's fuel, not the body (Cambridge University, 2017).

Any manufacturer promising a diamond from ashes alone is selling sentiment, not chemistry. We extract carbon from hair, fur, flowers and plants — materials where the carbon is still there to be purified. We are the only manufacturer honest enough to say this out loud, and we publish the analysis.

05 Chain of custody

Verified by CCIC.
Optional ILDA upgrade.

EVERY STONE SHIPS WITH INDEPENDENT,
NATIONAL-LEVEL TRACEABILITY
AS STANDARD — NOT AS AN ADD-ON.

Standard · Included

CCIC National Traceability

Every memorial diamond ships with a traceability certificate independently issued by China Certification & Inspection Group, a national-level inspection body.

Unique CCIC verification QR code
Full chain-of-custody timeline
National-level inspection & certification

Optional · Upgrade

ILDA Provenance

International Life Diamond Association membership adds a cross-border, mutually recognized provenance layer for partners who need dual attestation.

Cross-border mutual recognition
Industry standard alignment
Additional verification layer on request

What CCIC verification actually means: China Certification & Inspection Group is a national-level inspection body, independent from any manufacturer — including us. Each certificate carries a unique QR code that resolves to the stone's chain-of-custody timeline: intake date, purification gate result, growth chamber, grading record.

Your clients can verify their diamond's provenance themselves, in seconds, without contacting you or us. For partners selling into markets where memorial diamond provenance is contested, that independence is the difference between a claim and evidence.

11 Partner questions

Asked by every
procurement team.

STRAIGHT ANSWERS, IN FULL SENTENCES —
THE SAME ONES WE GIVE
ON THE FIRST CALL.

Q.01Do you make memorial diamonds from ashes?

No — and no manufacturer honestly can. Cremation destroys the usable carbon: a body yields 2–3 kg of ash holding only ~0.3% carbon (6–9 grams), locked in bone-mineral carbonate — and 67–91% of even that trace derives from the furnace fuel, not the body. We extract carbon from hair, pet fur, flowers, and plants instead, where the carbon is intact, and we publish the full analysis behind this position.

Q.02How long does production take?

Around 60 days end to end. Crystal growth alone runs 18–25 days at 5.5 GPa and 1,450 °C inside our HPHT presses, preceded by patented carbon extraction and purification to 99.95%+, and followed by laser cutting, polishing, and 4C grading with CCIC certification.

Q.03What certification comes with each diamond?

Every stone ships with a CCIC national traceability certificate as standard — QR-verifiable provenance your clients can check themselves, in seconds. An ILDA provenance upgrade is available for partners who need cross-border dual attestation.

Q.04What sizes and grades do you manufacture?

Standard carats are 0.5, 1.0, 1.5, and 2.0 ct, graded colorless E–H only, VS clarity, Ideal cut, grown by HPHT synthesis. We deliberately do not produce colored diamonds — one grade band, one standard, no exceptions per batch. Custom sizes are available on request.

Q.05Do you ship under our brand?

Yes — full white-label. Production, certification, packaging, and documentation carry your brand name; customs documentation is included. Express delivery runs 3–7 days to North America, 3–5 days to Europe, and 2–8 days across Asia-Pacific, insured and tracked.

Q.06Is there a minimum order or capacity limit?

Current capacity is 500 ct per month across multi-chamber HPHT systems with a confirmed scaling roadmap. There is no minimum order — start with a single pilot diamond to validate quality and branding. Volume timelines are structured per partner and detailed in your custom proposal — regional distributors can also negotiate exclusive territory.
