Suffragettes worried by their depiction as frumpy masculine badly dressed women in cartoons of the time decided to dress smartly and in a feminine fashion. Emmeline Pethick-Lawrence designed the suffragette colours as green for hope, white for purity and violet/purple for loyalty. Women started to wear these colours in support of the cause and in particular in discrete pieces of jewellery. The more common stones were Peridot pearl and amethyst and the more expensive emerald diamond and violet/ purple sapphire. Mappin and Webb launched a range of suffragette jewellery and the fact that the suffragettes became sartorially fashionable helped their cause. It is not entirely a coincidence that the first letters of green white violet are the same as give women votes. This was commissioned as an 18th birthday present.
