An 18" four-strand black leather necklace with a 925 sterling silver mounted ancient Roman glass pendant. The pendant measures approximately 40mm x 47mm with the Roman glass stone measuring approximately 30mm. Finished with a lobster clasp closure. Comes with a Certificate of Authenticity. Ancient Roman glass colouring will vary.

Roman glass is genuine ancient glass that was 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, where Roman glass production was concentrated. The glass was produced by Roman craftsmen for practical use as vessels, flasks, and containers: the fragments used in contemporary jewelry are pieces of that original manufactured glass, recovered from archaeological sites. What distinguishes Roman glass as a jewelry material is not the glass itself — which was produced by the same basic silica-soda-lime formula as modern glass — but the transformation the glass undergoes during its two millennia of burial. Over approximately 2,000 years in the soil, a process of chemical weathering acts on the surface of the glass: the alkali components of the glass leach out of the surface layer, leaving a silica-rich skin that builds up in thin, successive layers. These layers — each a few nanometres thick — act as a thin-film interference structure: incoming light reflects from the boundary between each layer, and the reflected wavelengths interfere with each other constructively or destructively depending on the thickness of the layers and the angle of the light. The result is 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 patina that accumulated on its surface over centuries. No two pieces of Roman glass are identical: the colour, intensity, and distribution of the iridescence depends on the specific burial conditions — soil chemistry, moisture, temperature, and duration — that the individual piece experienced. The 30mm Roman glass stone is mounted in a 925 sterling silver setting that frames and protects the ancient fragment, with the total pendant measuring 40mm x 47mm including the setting. The four-strand black leather cord provides a cord body that is visually and texturally distinct from a fine metal chain: the four strands give the cord a substantial, braided presence at the neckline that complements the organic, ancient character of the Roman glass pendant.

A significant collector’s piece and a refined gift for anyone looking for an ancient Roman glass pendant necklace where a genuine 2,000-year-old glass fragment in a 925 sterling silver setting hangs from an 18" four-strand black leather cord — with a Certificate of Authenticity included.

✨ How to Wear

Wear alone as a statement ancient glass pendant at the collarbone or below. The 18" four-strand black leather cord positions the 40mm x 47mm pendant at the upper chest. The sterling silver setting and lobster clasp complement the organic, earth-toned character of the black leather cord and the ancient Roman glass.
