What Exactly is Platinum?

Platinum is a chemical element classified as a transition metal on the periodic table. It is also known as a precious metal, and it is very rare.

Platinum is also a high density precious metal and is one of the heaviest metals used to make wedding bands.

Platinum is very malleable, and for this reason platinum is often used to make super strong wedding ring settings plus platinum rings crafted with amazing intricate filigree work.

Like most precious metals, platinum is so soft that it must be alloyed, (mixed), with another metal - usually ruthenium, iridium or cobalt - so that it can be hard enough to work with.

Pros of the Platinum Wedding Band

Platinum rings are extremely strong and durable. In fact, platinum is often used to make luxury watches because the small platinum watch parts will not wear down with time.

Platinum is a hypoallergenic metal and it is highly resistant to tarnish.

Rings made with platinum are also resistant to damage caused by chemical exposure include sulfuric and hydrochloric acids.

Like gold, platinum wedding rings are available in an almost limitless choice of styles, shapes, and stunning intricate designs.

Cons of the Platinum Wedding Band

Platinum can scratch, but a good polish will usually remove the scratches.

Platinum is a higher priced wedding band material and prices for platinum metals are very volatile. While this metal is 30 times rarer than gold, the price of platinum in the past has bounced from $774 an ounce to $2,252 an ounce. As a result, the cost and value of platinum wedding bands can vary.

Platinum rings can be expensive to resize or repair.

Platinum mines have a huge environmental impact, here is what you can do to lower your impact and find an Eco-Friendly Platinum Ring. (All of the EWR top picks are from eco resources).

Understanding Platinum Grades/Labels

Platinum is labeled according to the percentage of platinum weight in the product. For example, PT950 is 95% platinum by weight, PT900 is 90% platinum by weight, and PT850 is 85% platinum by weight.

In the United States, any items labeled "platinum", "PLAT", or "PL" must be at least 95% platinum weight (PT950).

Anything less than 95% platinum must be labeled with the metal it is alloyed with first. For example, "IRID/PLAT" is 90% platinum and 10% iridium (PT900) by weight.

Platinum Wedding Ring Grades and Alloys

The best platinum for wedding rings is PL950, anything less than PL950 does not last as long or wear as well with time.

The three most common platinum grades used in wedding rings are:

  • PL950/Iridium

  • PL950/Ruthenium

  • PL950/Cobalt

PL950/Iridium contains 95% platinum and 5% iridium by weight. It can be called 100% precious because iridium is one of the platinum group metals.

PL950/Ruthenium contains 95% platinum and 5% ruthenium by weight. It can also be called 100% precious because ruthenium is one of the platinum group metals too.

PL950/Cobalt contains 95% platinum and 5% cobalt by weight. This type of mixture is not 100% precious, but it is considered to be superior to other platinum grades.

What Type of Platinum Wedding Ring Grades are Best?

PL950/Iridium is sold in a lot of markets, but it is not considered to be the highest quality of grades. In fact, the mixture yields a soft metal which can bend, scratch, and pit. Overtime, a wedding band of this kind might begin to look dull or take on a lot of scratches.

PL950/Ruthenium is a durable grade of platinum, and it is almost scratch resistant. It can also achieve a beautiful mirror polish.

PL950/Cobalt is widely considered to be the highest quality of platinum alloy used in wedding bands. This type of mixture is strong and durable, it can be worked into a number of shapes and designs, and it has an extremely bright look to it; almost as if the ring has been lit up from the inside.

While Cobalt alloys can cause allergic reactions in some people, reactions to PT950/Cobalt are pretty rare.

Shopping Tips for the Platinum Wedding Band

Always ask about what type of metal the platinum has been alloyed with. For example, some stores sell PL950 but they never define what the platinum has been alloyed with.

Since platinum is expensive to resize, take at least two ring finger measurements using at least two different sizers before you purchase your rings.

Obtain a certificate or receipt with your purchase which states the grade of the platinum ring and what it has been alloyed with.
