Thank you for spending time helping me.
In 2000 the ring was on auction as a tourmaline. In March this year as I handed it over for auction they believed it to be a peridot but they changed the text as they put it up for sale to be a “stone” and not a peridot.
She checked the hardness of the stone in the auction house. It must have been 6.5-7 but she didn’t tell me. I don,t know why she changed her mind regarding it being a peridot. It was not until after I picked up the ring I found out about the auction in 2000.
You are probably right that it is a syntetic “stone”.
Thanks again
