Natural champagne diamond pearl gold plated sterling silver size 8 ring

This is a superb creamy golden pearl (it is most probably south sea, but I’m selling it as freshwater) and natural / genuine champagne diamond gold plated sterling silver ring. There are 3 rows of diamonds on each side of pearl. They test positive for diamond with the selector II diamond tester. It is a size 8.0 and it’s stamped STS and 925 on its shank. In unused vintage condition.
