Any macro lens which can give a 1:1 magnification will be good for ur purpose. u didn't state ur camera s9 we wouldn't know the exact lens to recommend. but if u happen to be a Sony user, u can get a 30mm 1:1 macro lens for $200 2nd hand, which should be the cheapest macro lens of all systems.
24-105 and 70-200 (f4). these 2 should do.... without proper finishing and polishing equiptment (I am guessing) being homemade jewelleries, I would not go for macro
spend a little money at Mass Sellers section on some cheap and good lighting equiptment and maybe a tripod ...... AND a good anti-static brush/cloth from your neighborhood Daiso or similar?
for flattering product photography, using light well is often more important than having better lenses (esp in your case with the lenses you have currently) ..... i use a 28-135 3.5-5.6 and a cheap 50/1.8 most of the time on smaller things
If u r shooting for online brochure, no harm using macro lens to create nice bokeh and reveal lots of micro details, but if the image is for shopping cart, then do check DOF, it's often better to have the whole thing in focus so that shoppers can see the entire piece clearly. Personally, i would use the lens that better suit the purpose.
