Flower Agate is arranged as a material-led collection. The catalogue records tumbled stones as the current shape and Tumbled Stone as the associated product-type label. Because no other leading form is documented here, the draft keeps the assortment within that single recorded category.
Use the material, shape, and product-type labels together: Flower Agate, tumbled stones, and Tumbled Stone. Any further distinction should come from confirmed entry-level data rather than inferred forms.
