Roman Glass is an ancient glass, discovered in archaeological excavation sites in Israel and in other Mediterranean countries.The fine Sterling Silver Roman Glass Jewelry is one of the most popular types and styles originated from Israel enabling to wear an entirely unique piece of 2,000-year-old history. The glass in this aqua-hued jewelry began life as a vase, jug, or vessel. Uncovered from ancient Roman archaeological sites in modern-day Israel, each fragment has been textured and colored by centuries of wind and weather. Each bear the marks of not only its past life as a household or temple object but also the very earth in which it rested until being transformed into a unique accent. Each piece of Roman glass is framed by a sterling silver bezel.

The designs for the jewels are based on artifacts and drawings also discovered on the archeological digs. The Roman Glass is a beautiful piece of history dating back 2,000 years to the time of the Roman Empire. The Roman Glass used for jewelry today in Israel is found in archeological digs throughout the land of Israel. The natural phenomenon which the glass has undergone over the many years it has been buried have given it the unique and beautiful aqua shades we enjoy today.Initially, in the Roman empire, glass was mainly used for vessels and available only for the wealthy. At that time, glass was manufactured by core forming, casting, cutting and grinding. However, since the invention of the glass blowing, glass was available to the public in vast numbers, mass produced in a large variety of shapes and forms. Due to the great popularity of glass during those ancient times, we today are priviliged to make use of these gorgeous historical pieces with which we enhance the beauty of our jewelry.
 
Ancient Israel, due to its large stretches of sandy dunes and beaches, was one of the largest glass producers of the Roman Empire. These same sands helped preserve the glass through the centuries, shaping and tempering it into the jewelry-quality pieces being excavated today.
Today the fragments of the 2000 years old Roman Glass that were once part of the lip of a goblet, jar, or other vessel are used in Israel to create beautiful jewelry that mixes the typical blue and green old glass excavated from archaeological digs with silver or gold creating a piece of art and history to wear with love. 

A certificate of authenticity is available for the Roman Glass jewelry.
 

It is interesting to know some facts about the glass history and the Roman Glass history, collected from several sources.
 
The History of Glass
 
Glass is formed when sand (silica), soda (alkali), and lime are fused at high temperatures. The color of the glass can be altered by adjusting the atmosphere in the furnace and by adding specific metal oxides to the glass "batch" (such as cobalt for dark blue, tin for opaque white, antimony and manganese for colorless glass).
A venerable legend perpetuated as late as the seventh century A.D. in the writings of Isidore of Seville gives a suitable miraculous explanation for the discovery of this elemental--yet truly wondrous--material - This was its origin: in a part of Syria which is called Phoenicia, there is a swamp close to Judaea, around the base of Mt. Carmel, from which the Bellus River arises . . . whose sands are purified from contamination by the torrent's flow. The story is that here a ship of natron [sodium carbonate] merchants had been shipwrecked; when they were scattered about on the shore preparing food and no stones were at hand for propping up their pots, they brought lumps of natron from the ship. The sand of the shore became mixed with the burning natron and translucent streams of a new liquid flowed forth: and this was the origin of glass.(Isidore of Seville, Etymologies XVI.16. Translation by Charles Witke.)
It is not surprising that the ancient authorities thought of Phoenicia as the birthplace of glass, for the Syro-Palestine region did indeed become a major center of glass production in antiquity, along with Egypt. However, glass seems actually to have been "discovered" not in Phoenicia, but in Mesopotamia. Archaeological research now places the first evidence of true glass there at around 2500 B.C. At first it was used for beads, seals, and architectural decoration.
Some 1,000 years elapsed before glass vessels are known to have been produced. Vessels of glass quickly became widespread in the second half of the second millennium B.C. They were popular not only in Mesopotamia but also in Egypt and the Aegean.

Uses

At the height of its popularity and usefulness in Rome, glass was present in nearly every aspect of daily life-from a lady's morning toilette to a merchant's afternoon business dealings to the evening cena, or dinner. Glass alabastra , unguentaria, and other small bottles  and boxes held the various oils, perfumes, and cosmetics used by nearly every member of Roman society. Pyxides  often contained jewelry  with glass elements such as beads, cameos, and intaglios , made to imitate semi-precious stone like carnelian, emerald, rock crystal, sapphire, garnet, sardonyx, and amethyst.

Merchants and traders routinely packed, shipped, and sold all manner of foodstuffs and other goods across the Mediterranean in glass bottles and jars of all shapes and sizes, supplying Rome with a great variety of exotic materials from far-off parts of the empire. Other applications of glass included multicolored tesserae used in elaborate floor and wall mosaics, and mirrors containing colorless glass with wax, plaster, or metal backing that provided a reflective surface. Glass windowpanes were first made in the early imperial period, and used most prominently in the public baths to prevent drafts. Because window glass in Rome was intended to provide insulation and security, rather than illumination or as a way of viewing the world outside, little, if any, attention was paid to making it perfectly transparent or of even thickness. Window glass could be either cast or blown. Cast panes were poured and rolled over flat, usually wooden molds laden with a layer of sand, and then ground or polished on one side. Blown panes were created by cutting and flattening a long cylinder of blown glass.
 
AN INDUSTRY THOUGH Roman glassworking certainly was, it was one that maintained a remarkable degree of dynamism over the centuries. The shape and decoration of two of its main products -- the unguentarium and the wine beaker -- were being modified every few decades, sometimes quite sharply, and there were many new items of glassware introduced that expanded the glassworker's repertoire in significant ways.
 
The way that the Romans committed themselves so heavily to the maintenance of good ports all around the Mediterranean coastline and of fine roads that criss-crossed the entire Empire on land was also critical for keeping the Roman glassmaking industry so dynamic. Of course, the main purpose of such maintenance was to assure the easy movement of troops from one trouble spot to another, and of administrative information from one city to another. But these ports and roads also allowed the movement of people and their ideas.
 
Signatures and inscriptions in Greek indicate clearly enough that eastern Mediterranean craftsmen settled at various places in northern Italy and central Gaul; that north African and Syrian soldiers were conscripted to serve in the army in northern England, thereafter to settle there as tradesmen; and that businessmen of every background and philosophical persuasion traded wherever it was to their advantage to do so. Thus, every Roman city became a social melting-pot where technical innovations could be passed on, blending with or displacing old ideas, sometimes in the space of just a decade or two. The industrial activities of the Roman world responded accordingly, with a freshness of purpose and an ongoing rise in skill. 
 

Jewelry in the Roman Times
 
Ancient Roman glass jewelry reached its height during the Augustan age, at the beginning of the Empire. This meant that in many ways the glass jewelry were deprived of much of the expressive freedom one might expect and hope for. The buyers of this fine artistic jewelry were the conservative political. The period of peace achieved during the rule of Augustus and Augustus made this possible, especially after the vicious fighting of the Roman civil wars.
 
Ancient Roman jewelry in earlier times was derived from both Hellenistic and Etruscan jewelry. In addition, as Roman jewelry designs freed itself of Hellenistic and Etruscan influences, greater use was made of colored stones such as: topazes, emeralds, rubies, sapphires, and pearls. Trojan and Cretan artisans of the Minoan period, although working at opposite ends of the Aegean region, crafted earrings, bracelets, and necklaces of a common type that persisted from about 2500 BC to the beginning of the Classical period of Greek art 479 BC - 323 BC.
 
Roman jewelry was highly influenced by some of the designs of the places they conquered and established connections with. The creators spared no effort in making some of the most exquisite and ornamental compositions. Rings were a major symbol in the body of ancient Roman jewelry. Ornamental Roman jewelry was worn by women of high status. They often wore jewelry on their ears, neck, arms and hands. Ancient Roman designs and fashion jewelry also included seal rings, amulets and talismans. The cameo and hoop earrings were introduced in ancient Roman times.

The gold beads of ancient Rome were artfully shaped to create images of flowers and animals. The most common fact that is assumed by most is that the ancient Roman jewelry has a similar resembles to the Greek and Etruscan jewelry.
