Questions, Answered
Before you ask.
How long does the hallmarking process take?
Thanks to advanced laser systems and an optimized workflow, most jobs settle the same day — and never beyond 24 hours.
What technology is used for gold testing?
State-of-the-art computerized XRF (X-Ray Fluorescence) — a non-destructive method that measures precious-metal purity with absolute precision.
Is there weight loss during old gold melting?
No. The entire melting sequence is transparent, well-documented and executed under strict digital weight parameters — what goes in is what’s accounted for.
Do you collect items from our shop?
Yes — our dedicated, secure pickup & drop team collects consignments from your shop and returns them hallmarked, with full weight statements.
