When comparing silver products, begin with the stated silver content. Purity describes the proportion of silver in the material, while fineness expresses that proportion in parts per thousand.
What does a fineness number mean?
A fineness of 999 means 999 parts silver in every 1,000 parts of material, equivalent to 99.9%. A marking of 925 corresponds to 92.5%. These numbers describe composition; they do not tell you the product’s weight or total price.
Read the product information together
Ask about the maker, stated weight, fineness and any identifying markings. Check how these details relate to the invoice or other documentation supplied. Appearance alone cannot establish purity, and a stamped number is not a substitute for appropriate verification.
Understand the scope of a standard
LBMA’s London Good Delivery rules specify a minimum silver fineness of 999.0 parts per thousand. Those rules apply to qualifying wholesale bars; a small retail bar or coin should not be assumed to carry that status simply because it has a 999 marking.
Before confirming your enquiry
Ask Annapurna Bullion to explain the specific product’s stated fineness, available markings and documentation. Confirm any verification arrangements before agreeing to a transaction.
