Competitor prices are indicative, converted from foreign currency at May 2026 rates, and do not include international shipping or NZ import costs. Actual costs may vary. Silmaril's prices are all-inclusive of NZD, GST, and domestic delivery.
When you order from an overseas provider, your hair travels internationally in one direction and the finished jewellery travels back in the other. Both legs add cost, time, and risk. Silmaril is based in Auckland — everything moves within New Zealand.
International providers price in USD, EUR, or CHF. By the time you pay in NZD, you absorb the exchange rate and any markup the provider applies. Silmaril prices in NZD with GST included — the price you see is the price you pay.
International providers often work through local agents or distributors in New Zealand to handle enquiries. Each layer adds margin. Silmaril sells directly — no agents, no resellers, no middlemen between you and the studio.
Providers like Heart In Diamond, Algordanza, and EverDear accept both hair and cremation ashes. Silmaril accepts hair only.
This is a deliberate technical choice. Hair contains carbon-rich keratin that can be purified to 99.99% and grown into a genuine diamond via HPHT. Cremation ashes are predominantly calcium phosphate with high impurity levels — incompatible with the HPHT process and unable to produce a quality stone.
If you only have ashes, we explain your options on our ashes page. If you have both hair and ashes, get in touch — hair from your loved one, however small the amount, may be sufficient.
Yes. Silmaril starts at NZ$1,980 all-inclusive. Heart In Diamond typically costs NZ$3,500+ for New Zealand customers once shipping and currency conversion are factored in — a saving of approximately NZ$1,500 or more with Silmaril.
Yes. Algordanza is a Swiss company. For NZ customers, prices typically start at NZ$3,800+ after currency conversion. Silmaril starts at NZ$1,980 with NZ delivery included — typically a saving of NZ$1,800 or more.
Yes. All four providers listed use HPHT technology — the same diamond-creation process. Silmaril's diamonds are rated VS–VVS clarity and D–H colour, the same range as international providers. Diamonds can be optionally certified by GIA or IGI. A lower price does not mean lower quality — it means lower overhead.
Comparable or faster in total. The HPHT growth period is similar (~50 days) across providers. However, NZ customers ordering from overseas providers must also account for international postage in both directions — adding weeks to the total process. With Silmaril, everything is within New Zealand.
The main reason would be if you have only cremation ashes — Silmaril does not accept ashes. International providers like Heart In Diamond and Algordanza do. If you have hair, Silmaril offers the same quality at significantly lower cost with faster NZ-domestic logistics.
