18kt w/g 1/3ct + ct Vintage diamond ring heavy

Beautiful and it is heavy. 18kt white gold. It is currently a 6 3/4. It has an older diamond in the center. The jeweler (going by memory) stated it was a heavy 1/3ct. It is SI1 in clarity, G in color.
It is white white. So pretty & sparkly. I paid roughly 1800 for it.
