Handmade Jewelry Category on Amazon
This category is separate from the Fine Jewelry category. Although the products are configured with a size dropdown, it is not handled on Amazon as a Matrix comprised of children products. Rather, it is treated as a simple product. As long as the single SKU has inventory, all sizes will be available. This is most likely because these products are made on demand.
