Using this pendant is easy. Just adjust the 16 - 18' adjustable chain to your preferred length and wear it with your favorite outfit. When you're not wearing it, store it in a jewelry box to prevent scratches. To keep it shiny, clean it gently with a soft cloth. If you want to clean it more thoroughly, use a mild jewelry cleaner, but make sure to rinse it well. Remember, the 0.70ct size with a GIA - certified diamond may take a few extra days to arrive, so plan ahead if you need it for a special occasion. Also, if you're interested in larger sizes, don't hesitate to ask.
