[QUOTE="Ratsy Brown, post: 4299082, member: 5040"]Hello I have here a fine quality micro mosaic gold brooch. It is presumably Italian, but I'm not sure about the gold mount. Did Italy ever use 14-15ct gold as a standard? The mount is unmarked so I have been acid testing on a touchstone. Completely dissolved immediately with 18k acid, but 14k acid doesn't touch it for at least 5 mins. So is the mount likely Italian, or maybe it was bought back to the UK and set in 15ct mount? 5.3cm x 4cm 21.54g Thanks for looking, hope you enjoy the photos [ATTACH=full]347714[/ATTACH] [ATTACH=full]347715[/ATTACH] [ATTACH=full]347716[/ATTACH] [ATTACH=full]347717[/ATTACH] [ATTACH=full]347718[/ATTACH] [ATTACH=full]347719[/ATTACH] [ATTACH=full]347720[/ATTACH][/QUOTE]
