Learn about Tungsten
Tungsten is a very hard and dense metal symbolized by a W or number 74 on the periodic elements table that is extracted from Wolframite ore. Tungsten is used as the filament wire in light bulbs because it melts at temperatures around 6,000 degrees F.
Hardness, assuring long lasting beauty. The tungsten carbide ring takes a brilliant high polish, like a mirror, and resist scratching longer than any metal ever offered to the public. Roughly ten times harder than 18k gold and four times harder than Titanium.
When Tungsten is processed with carbon and other elements it is transformed into Tungsten Carbide,WC, between 8 and 9 on the Mohs hardness scale, which is what most Tungsten rings are made of.
To make rings, tungsten is processed with carbon/other elements and ground to a powder.
The mixed powder is compressed into a ring blank The blank is fired in an oxygen-free furnace at around 2,500 degrees F, resulting in a solid dull blank .
The rough blank then goes through a multiple stage grinding process typically using diamond embedded tools. These are then polished to a brilliance and luster that holds for exceptionally long periods of time with little to no signs of wear.
