This is a vintage sterling silver piece from Israel. This Israeli silver work has a modern flowing design. I love the patterned matrix of this stone as it has love shades of cobalt blue to lighter blues. This is set into a sterling bezel and the sterling silver frame that surrounds the bezel is accented with sterling leaves. This large statement piece is stunning.
