Do platinum rings tarnish?
Just like gold, platinum doesn't tarnish, corrode, rust, or change color over the years. And like gold, it's a great metal for making jewelry. Platinum is 40% to 60% heavier than gold (depending on the karat weight of the gold). It's dense, malleable, (moves easily) and at the same time, very strong.
Whilst it may be true that platinum is harder than gold in its purest form, 18kt white gold is mixed with other metals, most commonly palladium, silver and copper to make it harder. This results in 18kt white gold being harder than platinum alloys, which are most commonly 95% platinum.
- Platinum is always more expensive than gold jewellery due to its unique and rare qualities. But not more expensive than diamond. It is a tough metal making it more durable and stronger than gold. It is denser and more material weight is required to produce a same ring than from white gold.

- Platinum is strong. Platinum, one of the strongest and most enduring metals in the world, is also one of the heaviest: it weighs 60% more than karat gold. It is ideal for jewelry worn every day because it exhibits little material loss, even after prolonged wear. Platinum is pure.
Though platinum is often thought of as being a very strong metal, this is only in comparison to gold. Titanium is the hardest natural metal in the world and is three times the strength of steel. This also makes titanium wedding bands much more dent, bend and scratch resistant than platinum.
- Ceramic is ranked slightly higher in hardness over tungsten on mohs hardness scale and therefore will chip and crack more easily then tungsten. Tungsten and Ceramic are both considered to be fragile if dropped on a hard surface floor. Don't be surprised if you break your ring or even worse, chip the tiled floor.
- Platinum and titanium credit cards typically have higher requirements to receive the card than gold, silver or standard credit cards. You may have to meet strict credit eligibility requirements, spend a certain amount of money, or make a minimum income. Titanium cards are harder to get than platinum cards.
- Can Titanium or Tungsten Carbide ring be cut off? In an emergency situation where there might be a medical necessity to remove the band (such as hand or finger injury) titanium rings can be cut off with manual or power ring cutters.
Color (and Rhodium Plating) Both white gold and platinum are "white" in color. However, the color of white gold is actually more light-gray in color than pure white. The rhodium-plating process coats the jewelry with a fine white, shiny surface.
- Even though platinum lasts longer than gold or silver and wears down slowly, it still does wear. If you want, you can always take your platinum piece to a jeweler and ask to have it polished. The process will remove the scratches, and your jewelry will look like new.
- Platinum is way way more stronger than diamond. & diamond is way more harder than platinum. If you hit a diamond with a hammer, it will shatter because it is brittle. Whereas, a sharp edge of diamond will scratch platinum because it is harder.
- Yes, rings can be resized to be a couple of sizes to be bigger. But, it is not as straightforward as you'd think. For example, a ring can be successfully resized 4 sizes up if it has a thick shank of 3mm or more. Rings smaller than 3 mm could be weaker if they are resized up.
