Item Description Tungsten is a grayish-white lustrous metal with a high density, strong properties and the highest melting point of any other metal. Tungsten is a great metal for jewelry use because it will retain its polish longer than other metals and can resist damage and corrosion by most minerals and toxins in the atmosphere. Tungsten jewelry is polished to a mirror-like finish using diamonds, and unlike most other metals, will retain its perfect finish for decades. Jewelry made from Tungsten will never need polishing and is virtually resistant to scratching. Its tough endurance makes it the perfect metal for men?s jewelry items. It is hypoallergenic as well as environmentally friendly.
