Dear Customer, Please note that our beautiful opals have been photographed in the light. Opal colours will vary according to which lights and angles you hold them in. Also, please enjoy a complimentary, temporary chain as a gift from us. They are gifted at no extra charge so that the items can be modelled straight away. We recommend the separate purchase of a secure, solid gold/silver chain- and do not recommend the prolonged wear of the gift display chain.
