Medieval floral jewellery

Medieval period began in 500 AD to 1500 AD. In this period there were lot of the techniques used in order to manufacture jewellery; those techniques are plating, chasing, repousse, enameling, inlay, granulation, filigree, stamping, and casting. In the pictures below how flowers evolve in floral jewellery from the floral motif to 2-dimensional flower. In this period of medieval, they didn't have a specific flower that they use to make jewellery. I couldn't find much about the floral jewellery made in the medieval period. I like these ideas below of how floral was made and I can use them to make floral jewellery by imitating a rose.

Figure 1- Pinky signet ring, bronze

In figure 1 shows that casting technique was used to make floral jewellery.  I like how the floral motif was used to make jewellery in a simple way. 

Figure 2- Gerochristo, (unkown). Medieval floral locket pendant, gold and sterling silver, 

The image in figure 2,  the flowers on the locket pendant are 2-dimensional and are plated with gold so that they can stand out. I like the way colour is used and it so detailed. The contrast of the black, silver and gold makes this locket pendant beautiful and neat.
