How to Identify Jewelry Markings. Fine jewelry is stamped or engraved with a variety of markings to indicate the materials with which it is made and its purity. To the average person, these mysterious markings can seem like a foreign language. Knowing how to interpret them can be helpful; they tell you what type of jewelry you have in your collection and enable you to describe it to potential buyers if you wish to sell the jewelry. Note that a â950 Platinumâ mark indicates that jewelry is 95 percent pure platinum, or 950 parts pure platinum out of 1,000.
