ABOUT ANCIENT ROMAN GLASS jewellery - Ancient Roman Glass jewellery blends the mystique and romance of the ancient world, a unique beauty shaped by the forces of nature, and skilled modern craftsmanship. The result is a wearable piece of history that, with proper care, will be treasured for generations to come. THE HISTORY - Almost 2,000 years ago, the Roman Empire was the birthplace of new glass blowing techniques used to create items like plates, vases, bowls, and jars. Today, this ancient glass can be recovered in archaeological sites in Israel, which was a major centre for glass production during ancient times. Because Roman Glass jewellery is made of fragments of these ancient hand-blown glass objects, each piece varies in shape, thickness and colour. Every piece of Roman Glass jewellery is one-of-a-kind. NATURE'S TOUCH - The striking colours found in Roman Glass jewellery come from a thin natural layer called the patina that formed over the course of centuries as the glass lay in mineral-rich soil. Through a process of oxidation, the patina developed these beautiful and complex shades of blue, green, and other colours. MODERN CRAFTSMANSHIP - Skilled artisans carefully choose ancient glass fragments, clean them to reveal their colourful natural patina, cut and shape the glass, and mount the glass to make a finished piece of top-quality jewellery. Designers craft jewellery that calls to mind the ancient past, in a wide variety of modern styles.
