Refining and assaying
Which metals are refined?
Gold and silver. Gold is refined to 99.99% purity (4N), and silver products follow the fine-silver specification of SNI 319:2023.
What material can be processed?
Raw gold, jewellery scrap, industrial waste, and electronic components (e-waste). Every lot is received with origin documents, weighed, and recorded before it enters the refining line.
How is gold purity tested?
Purity is determined in GAR's laboratory by Furnace Fire Assay and verified with ICP-OES (Inductively Coupled Plasma Optical Emission Spectrometry) in line with SNI ISO 15093:2020. Testing happens before any commercial agreement and again after refining.
Which standards apply?
SNI 8880:2025 for fine gold quality and marking, SNI 319:2023 for fine silver, and SNI ISO 15093:2020 for the ICP-OES purity verification method.
What does the process look like?
Six gates: raw-material intake, sampling and first assay, refining, bar casting, purity verification and marking, then certificate, vault storage or delivery.
Is storage available?
Yes. Product can be held in a vault with 24/7 monitoring and insurance cover, or delivered securely to the customer.
Products and Nemas
What are SAVA and ALURA?
SAVA and ALURA are GAR's two precious-metal brands. SAVA is pure gold bars cast at the SIER refinery and issued with a product certificate. ALURA is still in development, and its denominations will be announced.
What is Nemas?
