An 18" 925 sterling silver 1mm box chain necklace featuring an ancient Roman glass cross pendant measuring approximately 14mm x 16mm. 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 not a property of the original glass but of the burial transformation it underwent over centuries. In this necklace, the ancient Roman glass has been cut and shaped into a cross form measuring 14mm x 16mm. Cutting Roman glass into a precise geometric form such as a cross requires working with a material that is both brittle and ancient: the glass must be cut without fracturing its burial patina or compromising the integrity of the iridescent surface layer. The result is a pendant whose form — the cross — is cut entirely from a single piece of 2,000-year-old glass, rather than a glass stone mounted within a metal cross setting. At 14mm x 16mm, the Roman glass cross is a refined, wearable scale: the 16mm vertical dimension gives the cross a clear presence at the neckline without overpowering the fine 1mm box chain. A box chain is constructed from square links — each link is a small hollow cube — connected in sequence to produce a chain with a flat, smooth surface and a rigid, structured appearance that is distinct from the rounded, fluid surface of a snake chain or the flat, interlocking surface of a cable chain.

A significant collector’s piece and a devotional gift for anyone looking for a Roman glass cross necklace where a genuine 2,000-year-old ancient glass pendant cut into a cross form hangs from an 18" sterling silver box chain — with a Certificate of Authenticity included.

✨ How to Wear

Wear alone as a refined devotional or collector’s pendant. The 18" box chain positions the 14mm x 16mm Roman glass cross at the collarbone. The fine 1mm box chain pairs naturally with silver and white gold jewelry.
