Receipts from selling tangible personal property may be deducted from gross receipts if the sale is made to a person who states in writing that he will use the property so purchased in manufacturing jewelry. The buyer must incorporate the tangible personal property as an ingredient or component part of the jewelry that he is in the business of manufacturing. The deduction allowed a seller under this section shall not exceed five thousand dollars ($5,000) during any twelve-month period attributable to purchases by a single purchaser.
