Silmaril is an Auckland-based memorial diamond service serving New Zealand. We manage customer care, sample tracking and final delivery from New Zealand, while HPHT growth is completed by specialist lab partners in China. Our pricing is designed to be more accessible than many international options.
We accept: Human hair · suitable pet fur, hair, wool or fleece (dogs, cats, horses, sheep, rabbits, and other animals)
We do NOT accept: Cremation ashes or bone ash. Ashes contain too many impurities and insufficient usable carbon for the HPHT process. Silmaril works exclusively with hair.
Output: A genuine lab-grown diamond grown by direct HPHT crystal synthesis from hair-derived graphite, not presented as a CVD diamond with HPHT post-growth treatment. The diamond grows continuously on a diamond seed. GIA or IGI grading is available as a paid optional upgrade on request.
| Product | Diamond | Metal | Price | Order |
|---|---|---|---|---|
| The Guardian | 1.0ct HPHT lab-grown | 18K gold chain, 2.7g, white or yellow gold; 75% pure gold | NZ$4,950 | Order |
| The Warmth | 0.5ct HPHT lab-grown | 18K gold chain, 2.7g, white or yellow gold; 75% pure gold | NZ$3,850 | Order |
| Loose Memorial Diamond | 0.5ct / 1.0ct / 1.5ct / 2.0ct, round brilliant, E–H, VS | Unset — velvet presentation box with traceability certificate | NZ$2,999 (0.5ct) / NZ$3,700 (1.0ct); 1.5ct / 2.0ct by enquiry | Enquire |
What's included in the price: Full HPHT creation process · diamond · jewellery setting · ILDA / CCIC traceability certificate · insured courier return delivery · return of unused hair.
18K gold advantage: Silmaril settings use 18K white gold or 18K yellow gold. 18K gold contains 75% pure gold; 14K gold contains about 58.5%. At the same finished weight, 18K contains approximately 28.2% more pure gold than 14K.
Optional extra: GIA or IGI gemological grading (additional cost — request before production or cutting so current fee and timing can be confirmed). The report documents the finished stone's reported 4Cs and laboratory-grown identification; it does not replace Life-ID process evidence.
Pet hair pricing: Identical to human hair. No surcharge for any species.

Yes. Hair contains carbon — the same element diamonds are made from. Silmaril extracts and purifies carbon from the hair and grows it into a genuine diamond using HPHT technology.
No. Silmaril accepts hair only — human or pet. Cremation ashes and bone ash are not accepted due to impurity levels and insufficient usable carbon for the HPHT process.
Loose diamonds are NZ$2,999 (0.5ct) or NZ$3,700 (1.0ct); email us for 1.5ct or 2.0ct. Necklaces are NZ$3,850 (The Warmth, 0.5ct) or NZ$4,950 (The Guardian, 1.0ct), each in 18K white or yellow gold with NZ delivery.
Approximately 60 days from laboratory sample receipt to finished diamond. Silmaril's customer delivery estimate is approximately 100 days from receipt of a suitable sample; customs or carrier delays may extend this estimate.
Yes. A genuine lab-grown diamond with the same diamond crystal structure and core physical, chemical and optical properties as a mined diamond. It is not cubic zirconia or moissanite.
It is the only customer biological material and Life-ID-tracked biological carbon source for the order, and it is never mixed with another customer's material. The HPHT cell also uses a diamond seed and metal catalyst; Silmaril does not claim every carbon atom in the finished crystal can be individually attributed to hair alone.
Silmaril provides the available Life-ID-tagged photo and milestone video records for intake, shipping handover, carbon extraction, graphitization, HPHT growth milestones, cutting, setting, and dispatch. This is not uninterrupted video inside the sealed high-pressure growth cell.
Yes. It is a paid optional upgrade; request it before production or cutting so current cost and timing can be confirmed. It documents the finished stone's reported 4Cs and laboratory-grown identification, while Life-ID records the submitted sample's journey.
Silmaril uses direct HPHT crystal synthesis from hair-derived graphite, not CVD growth followed by HPHT post-growth treatment. An optional IGI or GIA report can provide independent documentation of the finished stone's laboratory-grown identification and any growth-method or treatment information included in the report.
Yes — all of New Zealand. Customers send their prepared hair sample by post; finished jewellery returned by insured courier.
Yes. Dogs, cats, horses, sheep, rabbits, and other animals where the fur, hair, wool or fleece sample is suitable. Same process, same price as human hair.
Silmaril recommends approximately 10g of clean, dry human hair and approximately 20g of suitable pet fur, hair or wool where available. The technical requirement may be lower depending on sample condition and target carat.
