This mug is divine, with a gem inspired handle and a beautiful iridescent green and turquoise vessel for holding hot liquid. This mug is a great addition for a crystal lover in the home. It is a tall, thin design with a mother of pearl finish on the outside of the mug. The inside is a tropical turquoise color. The mother of pearl gives the glaze an iridescent finish on the Crystal's and outside of the mug. It is microwave safe but not dishwasher safe.
