An 18" 925 sterling silver 1mm box chain necklace featuring an 8.5mm round ancient Roman glass stone set within a 32mm x 19mm 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, an 8.5mm round ancient Roman glass stone is set at the centre of a 32mm x 19mm sterling silver cutout cross. The cutout cross is a cross-shaped sterling silver form from which the interior of each arm has been removed: the cross is defined by its silver outline rather than by a solid silver face, and the arms of the cross extend outward from the central setting point where the Roman glass is held. At 32mm x 19mm, the cutout cross is a substantial pendant form — 32mm in vertical height and 19mm across the horizontal arm — whose dimensions are significantly larger than the 8.5mm glass stone it centres. This proportional relationship — a small ancient glass stone at the intersection of a much larger cross outline — gives the design a specific visual logic: the 8.5mm Roman glass occupies the crossing point of the four arms as the focal element of the composition, with the cross arms radiating outward from the glass in four directions. The ancient glass, at 8.5mm, is small enough that its iridescent surface reads as a concentrated point of spectral colour at the centre of the larger cross form rather than as a dominant surface in its own right. The 1mm box chain provides a structured, geometric base for the cross pendant, whose clean cutout outline and precise proportions are complemented by the regular square-link construction of the box chain.

A refined devotional collector’s piece for anyone looking for a Roman glass cross necklace in sterling silver — an 8.5mm ancient Roman glass stone centred within a 32mm x 19mm 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 cross pendant at the collarbone. The 18" 1mm box chain positions the 32mm x 19mm cross at the collarbone. The structured box chain pairs naturally with the geometric precision of the cutout cross design.
