Transform a lock of fur, hair or wool from your dog, cat, horse, sheep, or other beloved companion animal into a lab-grown memorial diamond — set in 18K gold and carried with you always.
View Collection Ask a QuestionThe bond between a person and their pet is one of the most unconditional forms of love. Losing a companion animal — a dog who greeted you every morning, a cat who slept beside you for fifteen years, a horse who carried you, or a sheep raised by hand — is a grief that deserves to be honoured.
At Silmaril, we treat every pet's material with the same care and reverence as a human loved one. The process is identical. The protocol is identical. The result is a real lab-grown diamond that carries the literal carbon of your companion's life.
There is no greater tribute.
From Labrador fur to Maltese coat — any breed, any size. A dog's devotion, made eternal.
Short-haired or long-haired, indoor or outdoor. Your cat's quiet companionship, preserved forever.
Mane or tail hair from your horse works perfectly. A rare and powerful tribute to a rare bond.
Sheep wool or fleece, rabbits, guinea pigs, and more. Ask us if you're unsure — we'll let you know if the sample is suitable.
Contact us to begin. Silmaril provides sample preparation and posting instructions. You return approximately 20g of clean, dry material — from a brush, groomer's clippings, a saved lock, mane, tail hair, wool, fleece, or other suitable sample. Material collected before or after your pet's passing is equally suitable.
Your pet's sample is received by Silmaril and is immediately assigned a unique biological Life-ID. It is logged, labelled, and held in its own dedicated container. Photo and milestone video records are tied to this Life-ID where available, creating traceability from this moment forward.
Pet fur is rich in carbon-bearing keratin. Carbon is extracted, purified to at least 99.95%, verified, then converted into crystalline graphite for HPHT diamond growth.
Bio-carbon graphite enters a dedicated HPHT growth cell with a diamond seed and metal catalyst. At typical conditions of approximately 5.5 GPa and 1,450°C, carbon crystallises on the seed over roughly 35–50 days.
The raw diamond is cut, polished, and set into your chosen piece. GIA or IGI certification is available on request. The finished jewellery and any remaining fur are returned to you by insured courier, anywhere in New Zealand.
Your pet's material is never combined with another customer's material.
Approximate laboratory cycle to finished diamond.
Extracted directly from your pet's fur.
Carat, colour, clarity and cut assessed.
The diamond rests above the horseshoe — your pet watching over you, a guiding light from above. Worn close to the heart, carried everywhere you go.
The diamond is cradled within the horseshoe — an eternal embrace. Like the warmth of your pet curled against you, held forever in gold.
Yes. Silmaril transforms pet fur, hair or wool — dogs, cats, horses, sheep, rabbits, and other animals — into lab-grown memorial diamonds using HPHT technology. 18K necklace prices start from NZ$3,850. Silmaril manages the order from New Zealand, while HPHT growth is completed by specialist lab partners in China.
Any animal with suitable fur, hair, mane, tail hair, wool or fleece containing keratin can be used. Dogs, cats, horses, sheep, and rabbits are common examples. Contact us if you're unsure whether your specific pet's sample is suitable — we're happy to advise.
We recommend approximately 20 grams of clean, dry pet fur, hair or wool where available to provide processing margin. The technical requirement may be lower depending on sample condition and target carat. Any returnable unused material is sent back with the finished piece.
Yes. Fur saved before or after your pet's passing works equally well. Grooming clippings, fur from a brush, or locks saved by a vet are all suitable. There is no time requirement on when the fur was collected.
Loose diamonds are NZ$2,999 for 0.5ct and NZ$3,700 for 1.0ct. Necklaces are NZ$3,850 for The Warmth (0.5ct) and NZ$4,950 for The Guardian (1.0ct), each in 18K white or yellow gold. Email us for 1.5ct or 2.0ct loose diamond pricing; pet fur has no surcharge.
Absolutely. Our One Guest, One Chamber protocol applies to every order. Your pet's sample receives a unique Life-ID when received by Silmaril and is grown in a dedicated chamber. It is never mixed with another customer's material.
Yes. It is carbon arranged in a cubic diamond crystal structure, not cubic zirconia or moissanite. It tests as diamond; specialised gemological equipment can identify its laboratory-grown origin.
Diamond production is 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 to delivery of the finished jewellery. Customs or carrier delays may extend this estimate.
Yes. Every diamond includes ILDA or CCIC traceability documentation. GIA or IGI grading is a paid optional upgrade; ask us before production or cutting so we can confirm current cost and timing. The report documents the finished stone's reported 4Cs and laboratory-grown identification, while Life-ID tracks your pet's sample journey.
Your pet's submitted hair is the only customer biological material and the only Life-ID-tracked biological carbon source for your order. It is never mixed with another customer's material. The HPHT cell also uses a diamond seed and metal catalyst, so we do not claim every carbon atom in the finished crystal can be individually attributed to hair alone.
We provide the available Life-ID-tagged photo and milestone video records for intake, shipping handover, carbon extraction and purification, graphitization, HPHT growth milestones, cutting, setting, and dispatch. This is a visual chain of custody for the available stages, not uninterrupted video inside the sealed high-pressure growth cell.
Yes. Our pet memorial diamonds are grown by direct HPHT crystal synthesis from pet-hair-derived graphite, not presented as CVD diamonds that have received HPHT post-growth treatment. The crystal grows continuously on a diamond seed. Optional IGI or GIA grading can provide independent documentation of the finished stone's laboratory-grown identification and any growth-method or treatment information included in the report.
No. The price is the same regardless of species — NZ$3,850 for The Warmth or NZ$4,950 for The Guardian. There is no premium or discount based on animal type.
18K gold contains 75% pure gold, while 14K gold contains about 58.5%. That means a same-weight 18K setting contains approximately 28.2% more pure gold than 14K. For a memorial piece, this gives the jewellery a higher precious-metal content and material cost base than common 14K settings.
No. Our One Guest, One Chamber protocol means each diamond is grown from a single individual's material only. This ensures full integrity and traceability for every stone. A separate order would be required for each pet you wish to honour.
Yes. We serve all of New Zealand. You send your prepared hair sample by post, and we return the finished jewellery by insured courier. There is no need to visit us in person.
Choosing Silmaril means your pet's sample is tracked carefully from intake to delivery, China lab logistics are managed for you, and pricing is shown clearly in NZD. You also have direct contact with our team throughout.
A lock of fur. A lifetime of love. A diamond that lasts forever.
