My large resin heart shaped pendant is lovely to wear; light and pretty capturing hydrangea petals in the resin.  It comes in a variety of colours - basically whatever coloured flower petals I have at the time.  These are largely pink, green or blue.  Each one will be unique.
 
The pendant meaures just over 3cm in length.  It comes with an 18" sterling silver chain but can also be provided with cord.
