Diamond and sapphires set in...silver? platinum? If I ever had my grandmother's or mom's diamond reset I'd want something like this--art nouveau-ish but not too fancy. And of course in white metal to go with my skin tone (and my wedding band).
Did you that most emeralds, sapphires and rubies are treated with chemicals and/or heat to enhance their colour & improve clarity by removing the natural inclusions. Aways check to see if the stone has been treated because although it enhances their beauty treated stones are not as valuable as their natural counterparts - ask for a lab report. http://fashionaccessoryshop.com/colored-precious-stones-emeralds-sapphires-rub.html
