Nova Opal Hexagonal Oxidized Copper Earrings
The stones are "Nova" lab grown opal(aka synthetic opal). The size of the stones is 12mm.
The earring hooks are Titanium, so they are great for sensitive ears.
The wire is solid copper that has been oxidized and polished for an antique look. Please note that copper naturally darkens with age and if necessary may be cleaned to lighten it back up.
The last photo shows back of the earrings next to a ruler for size comparison.
