Super real diamond circle necklace 1 inch …

I am the original owner of this necklace. It' approx .33 carat diamond (relatively clear very shiny) and 10k gold but there is no stamp. Currently a 925 chain is in place, which will be included. The ends of the chain must be extra tiny to fit. Circle one inch across so impressive size. Baguette cut diamonds. Looks great on. (RCC 120617)
