If an invoice is needed at the time of purchase, Lukfook Jewelry will recycle the old gold ornaments according to its selling price of gold on that day. Old gold ornaments are recycled if they are not bought at Luk Fook Jewelry, but the recycling price is lower. The recycled old gold ornaments can be exchanged for other new products in Lukfook Jewelry Brand Store, as long as the weight of gold is not less than the gram weight of the original old gold.
