When I moved from Italy more than two decades ago, I knew no one in the jewellery industry.
Coming from the diamond mining industry, I just fell in love with the creative process of making jewellery.
I came to realize over years that if I could bridge the gap between being creative and competitive at the same time, that I will be successful.
