Tools and materials aren’t included in the price. If you already make jewellery in metal, you can use the same tools for wax. If you're just starting out, get the essential tools to start with. You can always upgrade to the less essential tools (drills especially are expensive). You can buy tools and materials from all jewellery suppliers online or in shops. The one I use in Europe is Cooksongold and a big one in the US is Rio Grande. Have a google though, every country has their own suppliers. Cooksongold sells wax starter kits, so have a look for those at other suppliers as well.

Flat top ring wax tube with centre hole
Wax block or wax slices (slices are easier, less prep work)

Please just use whatever gemstone you have lying around for the projects. If you don’t have any gemstones, get CZs as long as you are practicing. Gemstones covered are cabochons, rosecuts, faceted and beads. Oval and round stones are going to be easiest and bigger stones easier than smaller. If you want a challenge, get a stone with a point as well.
