How can you tell if a platinum ring is real?
Look on the inner shank of the ring for any detailed letters or numbers.
If the shank has a visible, “PT” symbol, reads “900 PLAT”or has “950 PLAT” markings, then the ring is definitely platinum.
If the ring shows a 9K, 10K, 14K, 18K, 22K, with or without a series of three numbers, then the ring is not platinum..
How can you tell the difference between white gold and platinum?
The two main differences between platinum and white gold are the composition and price. White gold consists more of a mixture of durable metals like nickel, zinc and copper while platinum is more pure with 95-98% platinum composition. More platinum is needed to make a ring though, causing the price to be 40-50% more.
How can you tell if its stainless steel?
The nickel is the key to forming austenite stainless steel. So the “magnet test” is to take a magnet to your stainless steel cookware, and if it sticks, it’s “safe”—indicating no nickel present—but if it doesn’t stick, then it’s not safe, and contains nickel (which is an austenite steel).
Does stainless steel attract magnet?
Wrought, austenitic stainless steels, such as 304 and 316, are generally regarded as non-magnetic in the annealed condition, i.e. they are not attracted significantly by a magnet. However, if they are cold worked they will be attracted to a permanent magnet.
What are the two ends of a magnet called?
The end that faces the north is called the north-seeking pole, or north pole, of the magnet. The other end is called the south pole. When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another. This is similar to electric charges.
Does platinum have magnetic properties?

The best way to clean platinum is to use a gentle jewelry cleaner made specifically for platinum, like the inexpensive Connoisseurs Precious Jewelry Cleaner.

How often does platinum need to be polished?
six monthsPlatinum jewelry that is set with gemstones should be cleaned professionally every six months.

When this happens, you can take your piece to your qualified jewelry (or us)to have it re-polished to a high gloss look.
What is the difference between gold and platinum?
While gold and platinum are similar in price per gram, platinum is more dense and so more of it is required to make a ring. Additionally, platinum rings are usually 95% pure platinum, while 14k gold is only 58.5% gold (18k gold is 75% gold). Therefore, platinum rings are more expensive.
How can I test raw platinum at home?
Measure the volume of the sample (put enough water in the cylinder then place you sample in and see how much the level rises). Divide the measured mass by the measured volume and see what the number is. If it is 21 or higher then you either have platinum or something even more valuable then platinum.
