There are 2 parts to Quadrangle Series - Q1 & Q2. It was originally one necklace. WoonHung tore it apart, reconfigured into two, therefore renaming the necklace as Q1 and Q2. The simplified design allows the wearer to layer one or both pieces together. The colours were simplifed so that the beauty of each components take centrestage. Q2 is designed with matching earrings.
