When selling gold and silver jewelry in exchange for new ones, the value-added tax shall be calculated according to the actually received price excluding tax. That is, the value-added tax payable = tax-free price difference between trade-in and trade-in * value-added tax rate.

Article 1 of the Notice of the Ministry of Finance on the Collection of Value-added Tax on Gold and Silver Jewelry and Other Goods in State Taxation Administration of The People's Republic of China, People's Republic of China (PRC) (Caishuizi [1996] No.74) stipulates that considering the special situation of the trade-in business of gold and silver jewelry, the trade-in business of gold and silver jewelry can be subject to value-added tax according to the total price actually charged by the seller, and no value-added tax is levied.

Can I get a value-added tax stamp for jewelry?

You can't. The value-added tax regulations clearly stipulate that jewelry and other consumer goods shall not use special invoices for value-added tax and shall not be deducted.

Jewelry is a kind of consumer goods, it depends on who your invoice is aimed at. If it is for individuals, there is no need for special VAT tickets and no relevant information. Some units can't deduct tax, so it's unnecessary.
