7103 hsn code gst rate
Coloured gemstones are traded alongside diamonds in the same markets and by the same dealers. Precious stones other than diamonds, and semi-precious stones, whether or not worked or graded but not strung or set, are 7103 at 0.25%. Rubies, emeralds, sapphires and semi-precious stones used in jewellery come here. Strung pearls and stones made into jewellery move to 7113 or 7116 as articles.
Diamond gst rate and the trade chain
Diamonds move from rough importers to cutting units, then to polished diamond traders and jewellers. Rough diamonds bought at 0.25% are cut by job workers who charge 1.5%, and polished stones are sold at 1.5%. Jewellers set them into jewellery sold at 3%. Because the rates are low, even small classification errors cost little tax, but the HSN summary must still show each line correctly.
Lab grown diamonds
Lab grown and synthetic diamonds are reconstructed or synthetic stones under 7104. Their rate depends on the entries for 7104 in the fifth and sixth schedules. Check the current entry before billing them, as their treatment has been debated.
