Palladium has the appearance of a soft silver-white metal that resembles platinum. It is the least dense and has the lowest melting point of the platinum group metals.
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.
Palladium's lustrous silver-white color makes it an attractive choice for jewelry. Whiter than platinum, palladium does not need to be plated in rhodium or other alloys.
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. It is relatively hard-wearing.
Palladium is regarded as of low toxicity, being poorly adsorbed by the body when ingested. It may cause skin, eye or respiratory tract irritation, may cause skin sensitisation. Liquid may cause burns to skin and eyes.
Palladium will not tarnish and is great for filigree work, allowing for a broad spectrum of designs. Palladium rings are also 12% harder than Platinum, which translates into less signs of wear than Platinum.
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.
Palladium Is More Valuable than Gold & Silver
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.
Some people don't like the 'light' feel of palladium compared with platinum. Because it's a newcomer to the jewellery market, it's too soon to say whether palladium will keep its value so it's probably not the best metal to choose if you're looking to make a long-term investment.

With palladium sheets, the color is more like a gray powder than shiny silver. However, palladium coins, rings, earrings, and bars have a soft silver-white color. The silvery-white hue of palladium makes it very attractive and popular with buyers. It's typically whiter than platinum.
Palladium is highly magnetic because of its high magnetic susceptibility. Palladium is diamagnetic in bulk form and has the potential to become ferromagnetic.

used in jewellery is 95%, so the fineness stamp in their hallmarks are the same number, 950 (which refers to 950 parts out of 1000 being pure).
There are some tests which can be used, for example: -Relative to platinum, palladium will form a bluish oxide film when heated in a Bunsen flame and then, unlike base metals, will if heated in a reducing flame revert back to a silver colour.
Palladium does not tarnish and will keep it's white color indefinitely. It is much lighter than platinum, similar in weight to 14 karat gold. I find that at current precious metal markets the same design cost a bit less in palladium than it cost in 14k palladium white gold.
