7104.91.50.00 - Other

This HTS category, 7104.91.50.00, encompasses synthetic or reconstructed precious or semi-precious stones that are not diamonds, and fall under the "Other" designation within the context of worked or graded stones not yet strung, mounted, or set. This means it includes a broad range of synthetic or reconstructed gemstones like synthetic rubies, sapphires, emeralds, and amethysts, as well as their reconstructed counterparts, provided they have undergone some form of working or grading but are not yet incorporated into jewelry or convenient for transport via temporary stringing.

It is crucial to distinguish this category from its sibling, 7104.91.10.00, which specifically covers cut and suitable for jewelry manufacture diamonds. While both fall under the broader umbrella of synthetic or reconstructed stones, 7104.91.50.00 explicitly excludes diamonds and focuses on other types of gemstones. The key differentiator is the material composition and the absence of any specific suitability for jewelry manufacture that is stipulated for the diamond sibling.

As this is a leaf node, there are no further subcategories under 7104.91.50.00. Therefore, classification within this specific code relies on a comprehensive understanding of what constitutes "other" synthetic or reconstructed precious or semi-precious stones, excluding diamonds, and which are not temporarily strung for transit, nor specifically prepared for immediate jewelry assembly. This category serves as a residual for these types of stones that do not fit into more narrowly defined classifications.
