Platinum has a density of 18 g/cc while silver has 10.5 g/cc. Platinum unlike silver will not lose metal when scratched, nor will it lose its net weight over time from scraping. This is because the scratched metal doesn’t fall off; it’s only displaced. Platinum has a melting point of 3, 214.4° F while silver melts at 1, 763.24° F.
Platinum weighs more than silver and is much denser. Platinum also has a much whiter and shinier appearance, where as silver appears to have a duller gray appearance. Platinum is much more expensive than silver, because it is more difficult to extract it from the ground,
The table of elements learned by students in high school from their chemistry class can show the differences between silver and platinum. Silver (Ag) is a kind of “transition metal” belonging to the groups 3-12 in the Periodic Table. The element is known for its ductility, malleability and high ability to conduct electricity and heat.
• Platinum can form various oxidation states but, for silver, the oxidation state is +1. • Platinum is more ductile than silver. • Silver is known as a metal with the highest electrical conductivity and thermal conductivity. • Platinum is rarely found in nature than silver.
The innate differences between platinum and silver First, platinum and silver are innately different: this goes beyond appearances and into the properties of the metals themselves. Gold is rarer than silver, and platinum is rarer than gold, meaning platinum is much, much more rare than silver.
Fine silver, or 99.9% pure silver, is used in jewelry making but is very soft and not ideal for items such as rings. Platinum is generally combined with copper, palladium, cobalt, iridium and ruthenium. Most platinum alloys purity levels between 85 and 95 percent. Metals with less than 80% purity is not considered platinum.
Platinum, White Gold & Silver are 3 different metals. Platinum (Pt) is the rarest & the most precious of the 3. Platinum (Pt 950) is currently around 50% more expensive than Gold. It is naturally white & resistant to tarnish.
Silver, platinum, and palladium have similar colors, almost equal to the untrained eye. The primary differences are that silver stands out as the most common precious metal, but it is susceptible to corrosion and scratches. Seeing these flaws on coins is a good indication that the coin is pure silver and not a combination of different metals.
Platinum looks almost white, whereas silver has a more grayish tint to it and is also prone to oxidation which may cause it to start turning black. Bite down on the jewelry piece and see which one feels tougher, as you probably have seen done in movies numerous times.
