I have several smaller diamonds, ranging from .25 to .50ct. I have 2 pairs of earrings that I don't wear anymore. One is a GIA certified G SI1 1ctw pair and the other is an uncertified F/G SI1 .50ctw pair. I also have 4 uncertified G SI1 diamonds that are between .25-.30ct each. I don't know what I should do with them. Does anyone have any suggestions or ideas on how I can reuse these diamonds? Thanks for your help.
