This darker variant of Roman glass beads was created from glass colored in antiquity with metal oxides, producing deep cobalt and navy-blue tones. The material originates from regions of the former Roman Empire, particularly the Mediterranean basin and parts of the Middle East, where glass production and recycling were widespread.

The beads take the form of flat, round discs with a distinctly raw appearance. Variations in thickness, small surface losses, and irregular edges result from centuries of burial and natural weathering. Matte surfaces and chalky patina are typical characteristics of genuine archaeological glass.

The color palette is noticeably heavier than in lighter variants, dominated by cobalt blue, dark navy, graphite tones, and deep green hues. Lighter surface deposits and color shifts are natural outcomes of long-term interaction between glass, soil, and minerals.

Beads are sold on strands and can be worn as minimalist necklaces or used as raw material for jewelry work. This option is intended for those seeking a darker, more monumental expression of ancient Roman glass with strong historical presence.
