Answer :
1) I find commercials of designer & luxury jewelery brands the best (like commercials of Tiffany & co) The products are :- necklaces, bracelets, rings, silverware etc. (check the 1st poster attached featuring Rosé).
2) Look at the 2nd poster. It's a commercial of 'KAY Jewelers'. It shows the price of diamond ornaments & how they'll make the loved ones special during Valentines Day. It also gives the retail value, the discount rate & the type of material used (diamond & silver).
3) No, the claims aren't supported well. No good company would try to support their claims in the poster unless it's a video ad because they have to make the poster more eye-appealing & less cramped. But they've caught on the sentiments of the buyer & have given the retail value too which is important.
4) It fails to give the warranty of the jewellery bought & whether the ornaments can be given back to the store or not once its been bought. Since the product is diamond you can't be really sure of its market price & since there's a discount given you've no idea whether they are selling you cheap glass as diamond.
