The Land of Oz where rubies are slightly less abundant than emeralds...

Seriously, depending upon the quality of the rubies, I would go to Paris or London or New York and find the best jewelers in those cities. Any major or capital city is probably going to have a greater demand for rubies and gemstones, in general.

Go to a local jeweler who has there own jewelry shop. In the US, you can find a local jeweler through this link: http://www.jewelers.org/.

Online venues include retail stores like Zales and major sites like eBay or Amazon have rubies for sale. See rubies listed below as example of what you will find on eBay.
