"Dridu" communities produced and used gray or yellow fine pottery, but hand-made vessels were still predominant. Fine, gray vessels were also unearthed in the 9th-century "Blandiana A" cemeteries in the area of Alba-Iulia, which constitutes a "cultural enclave" in Transylvania. Near these cemeteries, necropolises of graves with west–east orientation form the distinct "Ciumbrud group". Female dress accessories from "Ciumbrud graves" are strikingly similar to those from Christian cemeteries in Bulgaria and Moravia. From an earlier date are the cremation cemeteries of the "Nuşfalau-Someşeni group" in northwestern Transylvania, with their 8th- and 9th-century "tumuli", similar to the "kurgans" of East Slavic territories.
