An 18" 925 sterling silver 1mm snake chain necklace featuring a round 23mm ancient Roman glass pendant with a rope and bead edge setting. The ancient Roman glass centre measures approximately 11mm in diameter. Finished with a lobster clasp. Comes with a Certificate of Authenticity. Roman glass colour will vary.

Roman glass is genuine ancient glass manufactured during the Roman period, approximately 2,000 years ago, in the territories of the Roman Empire — primarily in the regions of present-day Israel, Jordan, and Syria. The glass was produced for practical use as vessels and containers; the fragments used in contemporary jewelry are pieces of that original manufactured glass, recovered from archaeological sites. The defining characteristic of Roman glass as a jewelry material is its burial patina: over approximately 2,000 years in the soil, chemical weathering leaches alkali components from the surface of the glass and builds up a silica-rich skin in successive nanometre-thin layers. These layers form a thin-film interference structure that produces the characteristic iridescent surface of Roman glass — a shifting spectral colour play that is not a property of the original glass but of the burial transformation it underwent over centuries. No two pieces of Roman glass are identical in colour or iridescence pattern. In this necklace, the ancient Roman glass is cut and set as a round disc measuring approximately 11mm in diameter, mounted at the centre of a round 23mm pendant. The pendant setting is framed with a rope and bead edge — a decorative border in which the perimeter of the round setting is formed by a continuous rope-textured wire and a sequence of small spherical bead elements, producing a framed, finished edge that gives the pendant a more detailed and decorative profile than a plain bezel setting. The 11mm glass centre sits within this framed border, so that the ancient glass is both protected and presented within a setting that draws the eye to its circular form and iridescent surface. The 1mm snake chain is a fine, smooth chain in which small, tightly linked elements produce a continuous, flexible strand with a fluid drape and a bright polished surface.

A significant collector’s piece and a refined gift for anyone looking for a round ancient Roman glass pendant necklace in 925 sterling silver — an 11mm Roman glass disc set in a 23mm rope and bead edge pendant on an 18" snake chain, with a Certificate of Authenticity included.

✨ How to Wear

Wear alone as a refined ancient glass pendant at the collarbone. The 18" snake chain positions the 23mm round pendant at the collarbone. The fine 1mm snake chain pairs naturally with silver and white gold jewelry.
