An 18" 925 sterling silver .9mm snake chain necklace featuring a 20mm diameter ancient Roman glass pendant with a textured edge setting. Finished with a lobster clasp. Comes with a Certificate of Authenticity. Colour of Roman glass 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. Over approximately 2,000 years in the soil, chemical weathering acts on the surface of the glass: alkali components leach from the surface and a silica-rich skin builds up 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 a product of the burial transformation the glass underwent over centuries rather than a property of the original glass. In this necklace, the ancient Roman glass is cut and set as a round disc measuring 20mm in diameter, mounted within a textured edge setting. A textured edge setting is a circular sterling silver setting whose perimeter — the band of metal that surrounds and retains the stone — carries a surface texture worked into the metal rather than a smooth or plain finish. The texture of the edge gives the setting a visual and tactile quality that distinguishes it from a plain polished bezel: the textured surface distributes light across the perimeter of the pendant rather than reflecting it in a single smooth highlight, framing the 20mm Roman glass disc with a band of visually active metal. At 20mm, the Roman glass disc is a substantial circular form: significantly larger than the 11mm round Roman glass in the rope and bead edge variant, and large enough to present the full iridescent surface of the ancient glass as the primary visual element of the pendant. The .9mm snake chain is a fine, smooth chain whose sub-millimetre width gives it a near-invisible quality at the neckline, allowing the 20mm pendant to register without visual competition from the chain itself.

A significant collector’s piece and a refined gift for anyone looking for a round ancient Roman glass necklace in 925 sterling silver — a 20mm Roman glass disc in a textured edge setting on an 18" .9mm snake chain, with a Certificate of Authenticity included.

✨ How to Wear

Wear alone as a refined ancient glass pendant at the collarbone or below. The 18" .9mm snake chain positions the 20mm round pendant at the collarbone. The fine .9mm chain allows the 20mm Roman glass disc to be the dominant element at the neckline.
