Old Citrine Glass: English, from the mid-Wars period, a time of massive social and economic changes after the destruction and  loss of life brought about by WW1, when the purchasing power of the “working classes” assumed a greater importance. Much costume jewellery was produced, most of it completely disposable, but there was also a distinct genre of jewellery created that sought to closely resemble items of distinction, and Silver jewellery highlighting coloured glass imitating precious and semi-precious gemstones, such as this elegant necklace, was in that genre.
