India Bridal Set | Is Gold Jewelry Marked?

I have aquired a bridal set from India and there are no gold standard marks, or any marks for that matter. Is it 24K?

I believe the rubies and emeralds are real, but can't tell. Any input would be appreciated, about the age as well. It came in a faux red leather box with old 30-50's hinge clasps on the box, which is lined in blue velvet.

Thank you and best regards,
Deborah
