Guide to Precious Metals Palladium Jewelry. Palladium is the newest precious metal. A platinum group metal, palladium is rare, lustrous, and naturally white. Palladium has the purity and white tone of platinum but is less dense, making it more affordable.From the same metal family as platinum, palladium is a naturally bright white metal.However, palladium is lighter and less dense than platinum, which also means that it's lighter on your wallet.nd just like platinum, palladium jewelry is 95% pure, which means you get more precious metal in your jewelry: White gold is only 58.5% pure. And while white gold needs rhodium plating to keep it shiny, palladium jewelry does not. In fact, palladium is often used in white gold alloys.

What is Palladium Metal Used For The chemical properties of Palladium make it valuable in the manufacturing of commonly used materials such as nylon, polyester, and synthetic rubber. Mostly surprisingly and probably truest to its names sake, Palladium’s radioactive isotope is now being used in cancer treatments. Although not quite as rare as Platinum, Palladium is still a scarce resource and is found in a limited number of places throughout the world.

This massive stingray might be the largest freshwater fish ever caught The catch took about five hours, and the fishermen had to rotate in shifts to give respites from the back-breaking work. Using a classic rod-and-reel set-up and aboard a simple, long boat, the scientists and fishermen managed to capture the giant freshwater stingray in Thailand’s Mae Klong River last week.

Platinum vs. Palladium What is Palladium? Palladium is a platinum group metal, and though it is often confused for its more expensive counterpart, palladium is a separate elemental metal. Because of its likeness to platinum, palladium is also used as an industrial catalyst and is a common metal alloyed in the jewelry industry. Palladium and gold alloy, or white gold, is a common and crucial part of the fine jewelry market. In many industries, palladium is thought of as a lower-cost substitute for platinum because of its greater abundance. Although the actual amount of available palladium is unclear, palladium is usually a greater bargain when buying for industrial purposes, as it sells for nearly half as much as platinum.

Palladium Market Platinum group metals (PGMs) are rare precious metals with unique physical properties that are used in diverse industrial applications and in jewellery. Palladium, like gold, silver and platinum, is a precious metal, as well as one of the six PGMs, which also include platinum, rhodium, ruthenium, iridium and osmium. The unique physical characteristics of PGMs include: 1  Strong catalytic properties; 2  Excellent conductivity and ductility;

Indium Indium is a chemical element with symbol In and atomic number 49. It is a post-transition metal that makes up 0.21 parts per million of the Earth's crust. Very soft and malleable, indium has a melting point higher than sodium and gallium, but lower than lithium and tin. Chemically, indium is similar to gallium and thallium, and it is largely intermediate between the two in terms of its properties. Indium was discovered in 1863 by Ferdinand Reich and Hieronymous Theodor Richter by spectroscopic m
