Rapid growth of glass development began to expand during the Roman Era between 25-400AD, in the Mediterranean region. Shards of ancient Roman glass have been found in archeological excavations in Caesarea, Israel. These artifacts have a natural sheen of patina on the surface. Each piece has its own character and when an extraordinary piece is found, the artist creates a unique jewel around it. Often combined with original Roman coins of the period, all items come with a certificate of authenticity.
