When you find a timeless classic like this necklace, you know it has been created by an experienced jeweler.  This  Blue Topaz Hydrangea Necklace by Patrick Irla is one that will be treasured for generations. 

The hydrangea is a 3-petal style made of sterling silver with 18k gold details.  The raised veins and edges of the flower have been burnished to bring out the detail and contrast with the satin finish of the flower petals.  In the center is a 2.5mm sparkling sky blue topaz set in 18k yellow gold prongs.  The flower hangs on a sterling silver cable style chain, 16" long and 1.1mm thick.
