HS Code for Synthetic gemstones
Synthetic gemstones, specifically worked synthetic diamonds, are classified under HS code 7104.91. This heading covers stones that have been produced in a laboratory but possess the same chemical, physical, and optical properties as natural diamonds. The 'worked' designation means the stones have been cut, polished, or faceted, but they are not yet set or mounted into jewelry. This classification is distinct from 'unworked' stones (7104.21) and 'reconstructed' stones. The process of creation—whether Chemical Vapor Deposition (CVD) or High Pressure High Temperature (HPHT)—does not affect the HS code, provided the end result is a synthetic diamond. This code is essential for the jewelry industry to distinguish between natural and lab-grown diamonds for both regulatory and valuation purposes. The stones may be temporarily strung for transport convenience without losing this classification, provided they are not permanently set.

Common Misclassification
Synthetic diamonds are often misclassified under 7102, which is strictly for natural diamonds. Another common error is using 7104.99, which is the 'other' category for synthetic stones like rubies, sapphires, or emeralds. If the synthetic diamond is already mounted in a ring or necklace, it must be classified under 7113 (Articles of jewelry). Finally, imitation diamonds (like Cubic Zirconia), which are chemically different from carbon diamonds, are classified under 7104.99 or 7018 if made of glass.
FAQ
What is the HS code for synthetic diamonds?
The HS code for worked, but unset, synthetic diamonds is 7104.91.
Is a lab-grown diamond considered 'imitation' in the HS system?
No, the HS system distinguishes between 'synthetic' (chemically identical) and 'imitation' (chemically different). Lab-grown diamonds are 'synthetic' and fall under 7104.
