By 'historical diamonds' one can assume that you mean diamonds with a documented history.
The earliest document history of most 'famous' diamonds goes back several centuries. When one considers the evolution of the craft of cutting and faceting diamonds in parallel with the histories of these diamonds, one could conclude that the original values have always been improved upon, even given the loss of carat weight when 'famous' diamonds have been re-cut.
However, since most of these historical diamonds are in the possession of royalty, and some have been re-cut based on royal direction, and since many remain spoils of war, this means that there is no monetary value placed on these diamonds.

The value will depend upon the quality of the diamonds. You will need to get a jeweller to look at the ring. Diamonds are valued on more than just size, their colour ( shade of white) and clarity ( for example ) are important too.
No, diamonds are much more expensive than rubies But it depends on the size,
For their size, diamonds are extremely valuable, so conserving them in the sense of protecting them is important.
