HI again, I have tried to do some more proper pictures in order to look for marks or engravings. I hope that these details can be helpful for checking the work of goldsmith. Make special mention to the row of diamonds, the first and fourth differ from the second and third in terms of cut and clarity. What do you think about? The total diamond weight is 1,83 carats, ol diamonds. Rubies old cut, total weight 4,25 carats. Blue sapphire central stone 29,52 carats. I have been researching about this sapphire, but the proper characteristics in tone and hue from the Stone didn´t clarify much. Tha karatage of the gold is 19, but I´m not entirely sure. Thanks and regards!!!

The components look older, but truth be told, it could have been made within the month. The cast gold work is remedial, at best. The sapphire is very low quality, and very poorly mounted.
There is nothing about the piece that in my opinion, would definitively identify when it was made.

Hi All!
After research, I have verified that doesn´t look old, is old and antique, and its components (blue sapphire cabochon, old cut diamonds, rubies). A specialist from a famous auction house gemologist has inspected and has made an auction estimate of the piece. The ring I bought in India some years ago, as much as I know belonged to a Nawab- Please can anybody help me about these kind of pieces???? Thanks a lot for your Help!

I would also like to know how you know the exact weight of the stones without having them loose before mounting or having them taken out of the mounts...

Hello, For the weight of the cabochon sapphire, they had removed the stone to weight it. On the weight of diamonds and rubies I will ask how they calculate. As much as I know, they don't usually make mistakes in accurately, just sometimes negligible errors weight. But their techniques as much as I know are not very sophisticated!
