Sounds a little like around here. My wife got an old engagement ring from one dead grandmother and the same thing went down. Fast forward to about two years ago and my son is getting married. I showed him two rings I had to fight for that were my other grandmothers, that is a story for when I am not on the phone. It had one large diamond and two smaller ones on the edge with a couple more itty bitty ones in there two.My only diamond story:
My wife wears a 2.7 carat flat princess cut that was cut in 1907, so very few facets compared to today. It graded F flawless, and 1c loop clean clarity. Came off my great aunts dead finger in the mid 80s and sat in a safety deposit box till I told my mom I was going to propose. It was dingy and nasty. I know nothing about diamonds and asked, “Is it any good? My mom said, “It’s very good.” So I took it to have it cleaned and when it came out all the sales people in the jewelry store were crowding around and looking at it with their loops. They said it was the finest one they had ever seen. They said if it wasn’t cut so long ago with so few facets it could be worth a hundred grand. Paid $0, insured for $40k. Flawless might be rare but they must exist, because my wife has one.
The thing that shocked me is his wife had to have it sized up quite a bit, and she is about 100lbs, think college distance runner. I don't remember my grandma having that small of fingers but WOW it was tiny, only pic I have
