An oxidized 925 sterling silver adjustable bolo bracelet featuring a spiral design with a sideways cross and a 10.8mm x 8mm ancient Roman glass stone at centre. Adjustable up to 9". Finished with 4mm x 2.5mm labradorite bead ends. Comes with a Certificate of Authenticity. Colour of Roman glass will vary.

A bolo bracelet is a style of adjustable bracelet constructed from a cord or chain whose two ends pass through a sliding closure mechanism: the wearer adjusts the fit by sliding the closure along the cord to shorten or lengthen the bracelet at the wrist, and the two ends of the cord hang below the closure as decorative terminals. In this bracelet, the cord passes through an oxidized sterling silver focal element — a spiral design incorporating a sideways cross — at whose centre a 10.8mm x 8mm ancient Roman glass stone is set, and the two cord ends are finished with 4mm x 2.5mm labradorite beads. The focal element combines two design elements: a spiral form in oxidized sterling silver, and a sideways cross — a cross oriented horizontally rather than in its conventional upright position, a contemporary jewelry design convention that has become associated with modern devotional and cross-motif jewelry. The ancient Roman glass stone at the centre of the focal element measures 10.8mm x 8mm — a flattened oval whose width is approximately 1.35 times its height — set at the intersection of the sideways cross and spiral design. Roman glass is genuine ancient glass manufactured approximately 2,000 years ago in the territories of the Roman Empire, recovered from archaeological sites. Over approximately 2,000 years in the soil, chemical weathering builds successive nanometre-thin silica-rich layers on the glass surface that form a thin-film interference structure producing the characteristic iridescent surface of Roman glass. The oxidized silver of the spiral and cross setting provides a dark, low-reflectance frame that contrasts with the iridescent, spectrally shifting surface of the ancient glass at its centre. The 4mm x 2.5mm labradorite bead ends are oval labradorite stones used as the terminal elements of the two bolo cord ends. Labradorite is a feldspar mineral known for labradorescence — an optical phenomenon produced by light interference within the lamellar internal structure of the stone, generating a shifting display of blue, green, and gold spectral colour on the stone surface that moves as the viewing angle changes. The combination of Roman glass iridescence at the focal centre and labradorite labradorescence at the cord ends means this bracelet carries two distinct natural iridescent phenomena — both produced by thin-film interference, but in materials approximately 2,000 years apart in age.

A significant collector’s piece for anyone looking for a Roman glass bolo bracelet in oxidized sterling silver — a spiral sideways cross focal element with a 10.8mm x 8mm ancient Roman glass centre, adjustable bolo cord to 9", labradorite bead ends, and a Certificate of Authenticity included.

✨ How to Wear

Slide the oxidized silver focal element along the bolo cord to adjust the fit. The bracelet adjusts up to 9" at the wrist. The labradorite bead ends hang below the focal element as decorative terminals. The oxidized silver and natural stone combination pairs naturally with mixed-metal and earth-tone jewelry.

💎 Quality & Certification

• Certificate of Authenticity: Each bracelet comes with a Certificate of Authenticity confirming that the glass is genuine ancient Roman glass.

• Genuine Ancient Roman Glass: The oval glass stone is authentic Roman-period glass, approximately 2,000 years old, recovered from archaeological sites. The iridescence is a natural result of approximately 2,000 years of burial patina and is not applied or simulated.

• Natural Labradorite: The 4mm x 2.5mm bead ends are genuine labradorite. Labradorescence colour and intensity will vary between stones.

• Colour Variation: Colour of Roman glass will vary. The exact iridescence, colour distribution, and surface character of each stone is unique and cannot be replicated.

• Verified Authentication: We are committed to transparency and high-quality standards. Every piece is sourced exclusively from trusted professional suppliers who meet our strict quality and material standards.

⚠️ Important: Size & Scale Disclaimer

• Natural & Historical Variation: As a genuine ancient glass fragment, each Roman glass stone is unique in colour, iridescence pattern, surface texture, and exact dimensions. Colour will vary from the images shown. Labradorite labradorescence colour and intensity also vary between stones.
