platinum and gold
The oldest and most common jewelry alloy for platinum is 90% platinum, 10% iridium. You'll see various stamps, the most common maybe is 10% Ir Plat or something like that. Occasionally it's all spelled out, too. A newer alloy is 950 platinum, where the other 50 is usually cobalt. Usually that is stamped 950 Plat. or 950 Platinum. Those are the two most common, anyway.

NovaNet answer: Platinum and gold
The common mineral ore of platinum is called sperrylite, which is primarily composed of platinum arsenide (PtAs2). Other minerals containing platinum include cooperite (PtS) and laurite (RuS2), which can also be found in platinum-bearing deposits. These ores are typically extracted from alluvial and igneous rock deposits. Platinum is often obtained through complex refining processes due to its rarity and the presence of other metals in the ores.
Platinum has an atomic number of 78, which means it has 78 protons. The most common isotope of platinum, Platinum-195, has 117 neutrons. To find the number of neutrons in an isotope, you subtract the atomic number from the mass number; thus, Platinum-195 has 195 - 78 = 117 neutrons.
