sure i'll wait.
Estimates can run all over the map. Value of gemstones can only be determined by sight, since cut, color, and clarity are the major components of the value. Size (carat weight) for rubies, for instance, can run from $100 to $15,000 per carat.
The same is true of diamonds. Naturally, a number of smaller stones is not as valuable as one large stone, although both might add up to the same carat weight.
Since the rings are valuable, I would suggest you take them to a certified gemnologist for an appraisal. S/he can look at the stones through a loupe and determine their value based on qualities that you have to see to make an appraisal.
BTW, the image at imgur does not open. However, it really isn't necessary to see them, since value can run from $300-10,000 for each piece depending on the quality of the stones.
