There's no way for you guys on the forum to look at it and say "yes it's diamonds" or "it's all cubic zirconia", especially from the quality of photos provided!
That assumption is ill-founded. You won't find diamonds mounted in silver, so it's 100% certain in this case that we're looking at zircons (or other colourless natural gems), or cubic zirconia (artificial gems).
If you want a free appraisal of your jewellery finds, take them into Cash Converters or other pawnshop. They're experts in the field - they have to be to stay in business.
To give you a breakdown that may be helpful, the original retail price of this ring in a jeweller's shop window would have been around $100. Jewellery has high markups to compensate for slow turnover - typically 100% or more (hence the big discounts at sale time) - so the retail jeweller wouldn't have paid more than $50 to the wholesaler/distributor, who bought it from a manufacturing jeweller or importer for no more than $20-30. Actual scrap value of this ring might be as little as $5 and purely for the silver content - the stones have no significant resale value.
(In an earlier life I worked at a plastics factory, one of the owners of which had had made his money running jewellery stores and he invited me to bring in my detecting finds for appraisal. Unfortunately, it was usually a bit dispiriting) :/
