Last updated: August 2026 dataFinished articles set with diamonds, rubies, sapphires, emeralds, or other natural, synthetic, or reconstructed gemstones — as well as pearl jewelry and ornaments — are classified here, making this one of the highest-value per-unit import headings in the accessories trade. The heading explicitly encompasses synthetic and reconstructed stones alongside natural ones, so laboratory-grown diamond jewelry and hydrothermal emerald pieces are captured here rather than in a separate category. Valuation of gemstone-set articles is a frequent CBP focus, as the declared value of the stones themselves must be supportable by grading certificates, appraisals, or gemological laboratory reports.

Yes. The heading covers articles of precious stones whether natural, synthetic, or reconstructed, so finished jewelry set with laboratory-grown diamonds classifies here alongside natural-diamond pieces. However, FTC disclosure rules require that lab-grown stones be clearly identified as such in marketing and labeling, and CBP may request gemological certificates to verify stone origin and type during examination.
CBP expects commercial invoices that separately itemize the value of the metal setting and the gemstones. For significant shipments, independent gemological laboratory reports (e.g., GIA, AGL) establishing stone identity, weight, and quality grade are strong supporting evidence. Related-party transactions between a foreign manufacturer and a US importer receive heightened scrutiny, and transaction value may be challenged if the declared price is inconsistent with comparable market data.
