is there any way of telling the difference between platinum and silver?
Platinum is a precious metal that costs more than gold. It usually is mixed with other similar metals, known as the platinum group metals: iridium, palladium, ruthenium, rhodium and osmium. All of the platinum jewelry sold by Jaipurhandicrafts.com is the highest grade platinum, which is 95% platinum.
Platinum is extremely dense, and is much heavier than gold or silver.
Platinum has a remarkably high level of durability so it does not wear or tarnish like other metals. White gold is rhodium plated to give it the same white look as platinum, but eventually the rhodium wears off and the white gold takes on a yellow cast. White gold jewelry should be rhodium plated every few years to maintain its whiteness. Platinum does not yellow or tarnish and maintains its white appearance with little maintenance.
Platinum is not susceptible to problems like stress cracking or corrosion as can be the case with white gold. Though platinum can scratch, it is more durable than white gold and does not wear down or abrade like gold. Scratches can easily be removed by buffing, and all that is required to maintain platinum is to soak it in a mild solution of soap and warm water followed by a gently rubbing with a soft bristled brush.
Besides taking it to a jeweller to get it tested, no.
