Catalogue records place Purple Mica across formats that include bracelets, spheres, and towers. Grouping those entries by material makes the shape range visible without mixing Purple Mica with unrelated material categories.
Read the assortment by shape first: bracelets, spheres, and towers are the leading recorded formats. Product-type labels such as Crystal Bracelet, Crystal Sphere, and Crystal Tower provide a second factual distinction within the collection.
