Looking for Gold JewelleryVisit DWG Jewellery
DWS Jewellery measures gold plating thickness inside our own Jaipur factory. Our Fischer GOLDSCOPE SD 550 DPP+ XRF machine checks metal purity and plating thickness in microns, without damaging the piece. For jewellery brands, this means your gold vermeil specification is measured, recorded and reported, not just promised.
Gold vermeil is 925 sterling silver with a thicker layer of gold than ordinary gold plating. Our gold vermeil is made to a 2.5 micron gold specification, in yellow and rose gold. Thickness cannot be judged by eye: two pieces can look identical while one carries far less gold. An XRF reading shows the actual thickness, so brands can sell gold vermeil with confidence and answer their own customers' questions about quality.
On request, we provide a DWS Metal Assay & Micron Report generated with our Fischer XRF equipment. It records the metal purity and the measured plating thickness for the documented item. For example, one report for a gold vermeil SKU recorded 92.50% sterling silver and a mean thickness of 2.783 microns. Readings are specific to each piece and report.
When a brand needs independent proof, we can also arrange IGI (International Gemological Institute) Metal QC third-party testing and certification for submitted samples, alongside our own in-house checks. The IGI test below was measured by IGI, not by DWS: three readings averaged 2.511 microns of gold.
XRF testing is one part of a complete quality process at our 30,000 sq ft facility in Sitapura, Jaipur. Every piece goes through in-process inspections and a final inspection before shipment. Our quality checks include XRF metal analysis, plating-thickness verification, dimensional checks, stone-setting inspection, finishing inspection and packaging verification. Our premium micron plating is finished with a protective coating to improve tarnish resistance.
DWS Jewellery Private Limited is RJC Code of Practices certified (certificate 0000 7327, valid until 8 April 2029) and SMETA 4-Pillar audited. See our factory tour for photographs of our plating department and XRF equipment.
Yes. On request, we provide XRF plating-thickness reports generated with our Fischer XRF equipment. For gold vermeil, thickness verification can be provided according to your requirements.
No. Our own Fischer XRF is used in our quality process. Independent third-party testing, such as IGI Metal QC, can be arranged for submitted samples when you need it.
Gold vermeil uses 925 sterling silver as the base metal with a thicker gold layer (2.5 microns at DWS). Ordinary gold plating can be thinner and may use other base metals such as brass.
No plated jewellery is permanently tarnish-proof. Our micron plating and protective coating are designed to improve tarnish resistance, and proper care and storage greatly extend plating life.
