This is a polymer clay pendant - polymer clay is what I do mostly.The flowers that you can see on this piece are hand made by me (the central one is made by MarsDesign).
The process of making this flowers (Millefiori which translated from Italian is "thousand flowers") is not as difficult as it looks, although you have to be very patient.
Quote from Wikipedia:
Millefiori is a glasswork technique which produces distinctive decorative patterns on glassware.
The term millefiori is a combination of the
Venetian glassware. More recently, the millefiori technique has been applied to
polymer clays and other materials. Because polymer clay is quite pliable and does not need to be heated and reheated in order to fuse it, it is much easier to produce millefiori patterns than with glass.
This is what glass millefiori looks like.
And this is how I make my millediori canes:
