My wife and I got married in Balinesti, Romania (that's a village near Siret, which is in Suceava county about 3km from the Ukrainian border). We used the wedding crowns belonging to the church - they were fairly simple, silver crowns. They were also worn on the head and not held above as the Russians do. This is normal practice in the Romanian church.
The case of my godmother's wedding is interesting, though. She is Romanian and her husband is Cypriot. Apparently the Greek Cypriots have a tradition of being buried in their (flower) wedding crowns, but they married in Sibiu (Romania). In order to keep both sides of the family happy they used both flower and metal crowns, with the flower ones wrapped around the metal ones. They, of course, kept the flower ones.
Is this tradition of being buried in the crowns a normal Greek one, does anyone know, or is it specific to the Cypriots? I know that the precise wedding customs vary a lot even within a local church - my godmother, for instance, didn't have sweets thrown in front of her when walking round the tetrapod, but we did as is the custom in Bucovina.
