Hi John,
Think the colors are slightly different to Mdina Earthtones, more of a golden metallic hue to it. The spiral pattern has a slightly raised feel to it around the edge as if its been applied separately, almost like trailing. Definitely no its not Gozo glass (if that helps!), i did email Mdina glass, although as yet I havent heard back. Hopefully time will tell!
Thanks, Greg :thup:
