Palladium is a chemical element with the symbol Pd and atomic number 46. It is a rare and lustrous silvery-white metal discovered in 1803 by the English chemist William Hyde Wollaston.
Pd (notice the lowercase d) is a palladium mark.
Palladium is a chemical element that is similar to platinum. A rare, silver-white precious metal, palladium has been commonly used for fine jewelry since the 1930s.
Palladium has been growing in popularity since it was officially recognised as a precious metal with a voluntary hallmark in July 2009, compulsory from January 2010.
Nitric acid can be used to perform a quick test to differentiate between palladium and silver. Palladium won't react to nitric acid, whereas silver will oxidize and turn a light brown color.
Like other Hardmode ores, Palladium is generated upon destruction of an Altar with a Pwnhammer, it is immune to all types of explosions and requires at least a Molten Pickaxe to mine. It can also be obtained from Crates.
Platinum is denser — and stronger — than palladium. It's also resistant to rust and corrosive materials. Palladium is durable, too, but less so than platinum. Another interesting fact about both metals is that, when they get scratched, they don't lose any metal.
The international palladium hallmark is a five sided (pentagonal) shape with a curved base. In the UK, each number is instead surrounded by a circle.
Marks saying “Platinum”, “Pt”, or “Plat” must have at least 95% Platinum. No Platinum marks mean there is less than 50% Platinum in the piece. Meanwhile, Palladium fineness hallmarks are: 999 (99.9% Palladium)
The palladium hallmark
Standards of palladium hallmarking are either 500, 950 or 999 parts per thousand, as indicated below. The optional pictorial symbol is of Pallas Athene, the Greek Goddess of War, Wisdom and Crafts.

In fact, it's more valuable than gold and silver, in part because of demand fueled by its use in the manufacturing of electronics and industrial products. It also tops platinum when it comes to current market value. On average, prices for palladium rings today are around $2,000, according to Brides.com.

Palladium is a lustrous silver-white metal. It has a face-centered cubic crystalline structure, at ordinary temperatures it is strongly resistant to corrosion in air and to the action of acids. It is attacked by hot acids, and it dissolves in aqua regia.
Platinum jewelry should be stamped “PT” for pure platinum or “PT900” or “PT950,” indicating the number of parts per thousand that are pure platinum.

Like most other precious metals Palladium does scratch. Despite being harder than Platinum, it will nevertheless pick up scratches.
It is now cherished for its lustrous silvery-white finish and because of its similar properties to platinum. Palladium is resistant to corrosion and will not tarnish in air.

The quick answer is no, Platinum on its pure form is not magnetic (a paramagnetic metal). It is also hypoallergenic, which means that it will not react to sweat, will not tarnish, nor corrode.
It is estimated that palladium is still about 15 times rarer than platinum, making it significantly more expensive per ounce. In fact, palladium is currently the most expensive among the four major precious metals (platinum, gold, and silver).
