Murano glass CHALCEDONY flat band ring Certificate of Origin

Beautiful blend of various sea / ocean blues

The Chalcedony glass technique was originally discovered in Egypt during Roman times. During the 15th century it was rediscovered in Murano, Italy. Then in the late 19th century this ancient artistic technique was rediscovered by Murano master glass maker Lorenzo Radi.

The Chalcedony glass is created by mixing scraps (of colored and either white opaline or iridescent and Cristallo glass) and fusing them together under a high temperature. Once fused, mineral oxides* are repeatedly added to the mixture to create its unique colors. This mixture is blown into different forms while the distinguishing streaks from the oxides become prominent throughout the curves of the blown glass.

*cobalt oxides create blue colors; nitrate of silver create a matte appearance, etc.

Murano island is a series of islands linked by bridges in the Venetian Lagoon, north of Venice, in Veneto region, northeastern Italy. Founded between the 5th and the 7th century, and it experienced its major development after 1291, when glass furnaces were moved there from Venice. For centuries the secrets of artistic glass craftsmanship are guardedly passed on from father to son. To call it simply glass may not be most appropriate - rather Tommasi prefers to call it 'jewels in glass'.

Murano glass products are appreciated around the world for their beauty, quality, workmanship and prestige.

Each piece is unique and not produced by machines. No two pieces are exactly the same. Few Murano Glass items are transparent, usually they are brightly colored. Natural imperfections of the glass are common. You can see the master glass worker's craftsmanship in each piece.

The characteristics of original Murano glass are based on the quality of the decorations: gold 24 carats, silver leaf, platinum, alexandrite, agate, etc. For example, when topaz is forged in fire along with gold; aquamarine is forged with silver; emeralds are forged with aventurine all comes to life by simple movements of the master glass worker's hands.
