I Have a large 58ct mozambique ruby i have had for many years, i wonder if anyone has a rough idea of its value?
I got it from a friend for 3k many years ago.
Any help would be greatly appreciated

Are you absolutely sure that this is a natural ruby and not lab made? If I recall correctly, the largest gem-quality ruby is 55 carats, and sold for about 34 million US dollars. I would get this checked by a gemologist or jeweler, it is very likely to be lab-made in my opinion.

As I can see from the picture, it is natural. However, if it is glass-filled, it would be worthless. The best way is to take it to a jeweler.
