Who we are

A gold and silver refinery that works on proof, not promises.

PT Golden Alura Refineri refines, assays, and casts precious metals in its own refinery in the SIER Industrial Estate, Surabaya — every batch assayed with methods held to SNI standards.

From raw material to certified bar, one line you can trace step by step — ending as SAVA & ALURA precious metal in your hands.
