If you’re looking for a new jewelry item, why not consider an iridium necklace? This beautiful white metal is one of the rarest and most durable precious metals. It’s also a good choice for women who don’t wear gold.
Iridium is the second-densest element in the platinum group of metals. It’s hard and brittle, with a silvery-gray color that can vary from faintly yellow to darkly gray with a slight tint of blue in its salts.
It’s also the most oxidation-resistant metal. This is important if you want to keep your iridium necklace looking its best.
Another popular plating option for platinum is rhodium, which protects it from scratching and tarnishing. It comes in a range of different finishes, including “black rhodium,” which gives the jewelry a dark, gunmetal look.
Rhodium is a microscopically-thin coating that costs around $60 to $120 per treatment. Over time, the rhodium will wear away to reveal the platinum underneath.
Ruthenium is another common metal used for plating, and like rhodium, can come in a wide variety of finishes. It can be applied to the outside of jewelry, creating a glossy, lustrous finish that resists tarnishing and scratches.
It can be applied to the inside, too. This is especially useful for jewelry that contains diamonds or other white gems, where a dark ruthenium coating can make them appear more sparkly and bright.
It’s a very popular plating option, but it’s very expensive to produce solid iridium jewelry. The price of iridium is currently about five times as much as platinum, making it difficult for jewelers to afford.
