Mid Century Gold Spinel Ring

Beautiful mid century (1950's) gold and spinel ring. I bought this from an antique store that sold it to me as 9K gold (standard in the UK) but stamps could also indicate 10K. I'm not knowledgeable on stamps. This ring has the perfect vintage gold colour, almost rose gold with shiny little spinels all the way around. The intricate details really catch the light and twinkle. This would make a beautiful wedding band or a great stacker ring. Approximately a 6.5 ish (but will update). This ring would not be able to be resized since the pattern and little stones run all the way around.
