Stones, precious (other than diamonds) and semi-precious stones, unworked or simply sawn or roughly shaped, not strung, mounted or set.
Classification of uncut gemstones under HS 7103.10
HS code 710310 is the primary classification for natural precious and semi-precious stones, excluding diamonds, that are in an unworked or minimally processed state. This includes stones that have been extracted from the earth and may have been sawn to remove impurities or roughly shaped into blocks or pre-forms for later cutting. To remain under this code, the stones must not be polished, faceted, or drilled for stringing. They also cannot be mounted or set in any form of jewelry. This classification covers a wide variety of mineral species, provided they are of a quality used for decorative or gemstone purposes. It is a foundational code for the raw gemstone trade, allowing for the movement of mineral wealth before value-added lapidary work is performed. The distinction between precious and semi-precious is not strictly defined by the HS system, so this code encompasses everything from rough emeralds to raw quartz, provided they are natural and unworked. The roughly shaped provision allows for the removal of the skin or matrix of the stone, but any attempt to create facets or a polished surface will result in a reclassification to 710391 or 710399. This code is essential for tracking the international trade of raw mineral resources.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries marked * did not, so their figures add up what other countries recorded trading with them, and their exports are valued at buyers' CIF prices. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
