Loose Memorial Diamonds

SET IT YOUR WAY
Prefer your own design? A loose memorial diamond is the same stone as our necklaces — grown from your loved one's hair, One Guest, One Chamber — delivered unset in a velvet presentation box with its ILDA / CCIC traceability certificate. Ideal if you want a ring sized and set by your local jeweller, an addition to an heirloom piece, or a design of your own. Every loose diamond is round brilliant cut, E–H colour, VS clarity. Delivery estimate is approximately 80 days from receipt of a suitable sample, as no jewellery setting stage is required.
0.5 carat (~5.0mm) Enquire for pricing
A refined, precious presence — the same specification as The Warmth necklace, unset. Order by email
1.0 carat (~6.5mm) Enquire for pricing
Our most popular loose stone — substantial in hand and in the setting of your choice. Order by email
1.5 carat (~7.5mm) Enquire for pricing
A statement stone for a centrepiece ring or pendant commission. Enquire by email
2.0 carat (~8.2mm) Enquire for pricing
Our largest commission, produced in limited numbers. Enquire by email for current pricing and timing.

Larger carat weights may require more hair than our standard guidance of ~10g (human) or ~20g (pet). Once your diamond is delivered and signed for, setting work by a third-party jeweller is arranged at your discretion and is outside Silmaril's care. We are happy to suggest questions to ask your jeweller.

What's Included in the Price

NO SURPRISES
Diamond creation Included
The complete hair-to-diamond process — carbon extraction, 99.95%+ purification, graphitization, 35–50 day HPHT growth, cutting and grading.
Jewellery setting Included
The finished 0.5ct or 1.0ct diamond is cut, polished and set into one of seven 18K gold necklace designs. The Guardian and The Warmth offer white or yellow gold; the five new designs are shown in yellow gold. No additional setting fee.
18K gold advantage Included
18K gold contains 75% pure gold. Common 14K gold contains about 58.5%, so an 18K setting contains about 28.2% more pure gold than a same-weight 14K setting before craftsmanship and finishing are considered.
Sample guidance Included
Silmaril provides sample preparation guidance before you send your hair sample.
NZ delivery Included
The finished jewellery is returned to you by insured courier to any address in New Zealand. No shipping charge regardless of your location.
Return of unused hair Included
Any hair remaining after the carbon purification stage is carefully packaged and returned to you alongside the finished diamond.
Traceability certificate Included
Every diamond is delivered with a traceability certificate from the International Life Diamond Association (ILDA) or CCIC (China Certification & Inspection Group) at no extra cost — independent documentation that your diamond was grown from your submitted sample.
GIA / IGI certification Optional extra
Gemological certification by GIA or IGI is available on request at an additional cost. Contact us for current certification pricing — it can be arranged before or after your order.

Pricing Questions

FREQUENTLY ASKED

How much does a memorial diamond cost in New Zealand?

Our seven necklace designs use two price tiers: NZ$2,850 for 0.5ct (The Warmth, The Promise, The Flame and The Halo) and NZ$3,950 for 1.0ct (The Guardian, The Beacon and The Eternity). The Warmth and The Guardian prices are current special offers against their regular prices. Custom loose memorial diamonds from 0.5ct to 2.0ct are available by email enquiry.

What is included in the price?

Everything you need: the full hair-to-diamond creation process, the HPHT lab-grown diamond (0.5ct or 1.0ct by design), an 18K gold jewellery setting and chain, an ILDA or CCIC traceability certificate, insured courier return delivery, and return of any unused hair. The only optional addition is GIA or IGI gemological certification.

Can I buy just the diamond without a setting?

Yes. Custom loose memorial diamonds from 0.5ct to 2.0ct are available by email enquiry. Each is delivered in a velvet presentation box with its ILDA or CCIC traceability certificate — ready for your own jeweller to set.

Why does a memorial diamond cost more than a regular lab-grown diamond?

Regular lab-grown diamonds are mass-produced in large batches from standard graphite, spreading the production cost across many stones. A memorial diamond is made one at a time: carbon is extracted and purified from your loved one's hair, and an entire HPHT growth chamber is dedicated to that single sample for the full growth cycle — One Guest, One Chamber — with Life-ID tracking and traceability certification. You are not paying for a generic stone; you are paying for a diamond grown from one irreplaceable source of carbon. A mass-produced diamond can be replaced. This one cannot.

Why is 18K gold more valuable than 14K gold?

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. Our settings use 18K white gold or 18K yellow gold, not 14K.

Are there any hidden fees?

No. The listed price is fully all-inclusive for NZ customers — including an ILDA or CCIC traceability certificate with every diamond. The sole optional extra is GIA or IGI grading, which is available on request. Contact us for current certification pricing.

Is the price the same for human hair and pet hair?

Yes. There is no difference in price between human and pet hair orders: the 0.5ct tier is NZ$2,850 and the 1.0ct tier is NZ$3,950.

Are prices in NZD?

All prices are in New Zealand dollars.

Does the price include delivery?

Yes. The finished jewellery is returned by insured courier at no additional charge, anywhere in New Zealand.

Is a deposit required?

Full payment is made at the time of ordering via Stripe. If you have specific questions about payment arrangements, email [email protected] before placing your order.

How much does GIA or IGI certification cost?

Certification pricing varies with laboratory fees and the specific certificate requested. Contact us for current pricing. Certification can be arranged at any point — before or after your order is placed.

Why is Silmaril often more accessible than overseas providers?

Silmaril is a New Zealand service with simple, all-inclusive NZ pricing. You should compare current like-for-like offers carefully, because overseas pricing can vary by currency, setting, shipping, certification, and import costs.

How do I pay?

Securely via Stripe using any major credit or debit card. You can also email us with questions before paying — there is no pressure or obligation to commit before you are ready.
