The density of platinum is 21.4 g/cubic centimeter; the density of silver is 10.5 g/cubic centimeter. So...a quick way would be to determine the volume of the item (Archimedes' water displacement method still works) then weigh it on an analytical balance.
Silver is generally lighter and softer than platinum. Silver also tarnishes over time, developing a black or gray patina, whereas platinum retains its white luster. Additionally, platinum is more resistant to corrosion and is more valuable than silver.
The physical difference between silver and platinum is in terms of color. Pure silver is more whitish in color while platinum is more grayish than white. Silver has a lower density than platinum.

A cube of platinum of the same size as a cube of silver will weigh more.
Yes. Platinum is between silver and white.
One way to distinguish between silver and platinum is by their markings. Silver is typically marked with "925" or "sterling", while platinum is marked with "PLAT" or "950". Additionally, platinum is heavier and denser than silver, so you can weigh the ring to help determine the metal. If you're still unsure, a jeweler can perform a professional assessment.
Platinum is NOT silver. Platinum is much harder and many, many times more expensive.
Silver is a soft metal. Platinum is a similar color but does not change its shape easily and does not tarnish. Platinum is worth more than silver and gold.
no. Platinum is more highly valued than silver.
The chemical symbols for gold, silver, and platinum are Au, Ag, and Pt, respectively.
Platinum
980 is most likely a silver alloy rather than platinum. Platinum is generally marked as 950 or 900 to indicate its purity, while silver alloys typically range from 800 to 950 in terms of purity.
