Vintage Dragons Breath Glass Cabochon Locket Pendant Antique Gold Base Chain: 48cm + 6cm A locket pendant with a vintage Dragons Breath, featuring a brilliant blue sheen and ruby-colored sparkle. The stone size is a large 18x13mm, giving it a strong presence, and the impression changes depending on the viewing angle. Dragons Breath, also known as Mexican Opal, is a very beautiful and fantastical vintage glass characterized by a dragon-like red flame and a hologram-like floating blue. This is a highly recommended item!
