This stringent standard ensures a level of quality and durability that standard plating cannot match. While standard gold plating may have a layer as thin as 0.03 에게 0.06 microns and a lifespan of months, authentic vermeil offers a lifespan of years due to its substantial gold coating .

Using X-Ray Fluorescence (XRF) 기술, inspectors non-destructively verify the thickness of the gold layer to ensure it meets the minimum 2.5-micron standard . Every piece is visually inspected for color consistency, plating defects, 그리고 전체적인 마무리.
