There is almost complete absence of expensive jewelry and personal items from this period. Those items and artifacts that were discovered, show that economic inequality among the inhabitants of one locality was quite low. Some personal items distinguished the difference, at least when it comes to the ruling family, like in the case of the Seal of Strojimir. Still, though a quality work, it is an unpretentious and typical artwork of the day. The jewelry was not distinguished from the other Byzantine-influenced Slavs. It was made in the Byzantine artisan shops and in the Byzantine manner, which in turn was Roman in origin. Main surviving artifacts include female jewelry: earrings, rings, necklaces, pendants, etc. Older pieces were simple and cast from bronze, but in time more sophisticated techniques, like filigree, granulation and gold plating, were used, while the main material switched to silver.
