An 18" 925 sterling silver 1mm box chain necklace featuring a 20mm x 17mm oval ancient Roman glass stone set within a sterling silver cutout cross pendant. 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, a 20mm x 17mm oval ancient Roman glass stone is set within a cutout cross pendant in sterling silver. The cutout cross is a cross-shaped sterling silver form from which the interior of each arm has been removed, producing an open cross silhouette: the cross is defined by its silver outline rather than by a solid silver face, and the Roman glass oval sits at the intersection of the four arms of the cross, held within the open framework. The 20mm x 17mm oval Roman glass — a width-to-height ratio of approximately 1:1.18, producing a near-circular but distinctly oval form — is centred at the crossing point of the four arms of the cutout cross, where the oval glass is simultaneously the focal element of the cross and the stone within its setting. This is a design in which two historically significant forms — the ancient Roman glass fragment with its 2,000-year burial iridescence, and the cross as a devotional and symbolic form — are combined: the glass occupies the centre of the cross, and the cutout arms of the cross frame and direct the viewer’s attention toward the ancient glass. The 1mm box chain provides a structured, architectural base that complements the precise geometry of the cutout cross pendant.

A refined devotional collector’s piece for anyone looking for a Roman glass cross necklace — a 20mm x 17mm oval ancient Roman glass stone set within a sterling silver cutout cross on an 18" 1mm box chain, with a Certificate of Authenticity included.

✨ How to Wear

Wear alone as a refined devotional or collector’s pendant at the collarbone. The 18" 1mm box chain positions the cutout cross pendant at the collarbone. The structured box chain pairs naturally with the precise geometry of the cutout cross design.
