On its own, tungsten is a very hard and dense metal with the highest melting point of all metals: 6200° Fahrenheit or 3400° Celsius. By itself tungsten is vulnerable to scratches and damage, just like any other metal. It gains its extreme hardness by being combined with a carbon alloy, transforming it into tungsten carbide, with a hardness between 8.5 and 9.5 on the Mohs hardness scale, and it is almost impossible to scratch. Many manufacturers of tungsten carbide jewelry use cobalt as a binder alloy, mostly because it is cheaper to produce. The problem with cobalt is that it bonds with oils in the skin and leeches out of the ring, resulting in oxidation. The oxidation appears similar to tarnished silver, but cannot be removed by polishing or grinding. We use nickel as a binder alloy in our tungsten carbide. It is chemically inert, very hard, will not scratch, will not oxidize, and because it is hypoallergenic, there is no danger of irritation to the skin.

All our products are made of tungsten carbide 857, this means that it is made of: 85.7% tungsten carbide, 9.5% nickel, 1.8% tantalum, 1.5% titanium, 1% niobium and 0.3% chromium.

The manufacturing process.
Tungsten is mixed with carbon and other metals and ground into powder. The mixed metal powder is compressed under high pressure to form a ring blank. The ring blank then fired in an oxygen-free oven at around 6200° Fahrenheit or 3400° Celsius. The result is a solid metal ring with extreme hardness. The rough ring then goes through a 30 step process of grinding and polishing using a diamond tools.

Important facts about tungsten carbide:
• Tungsten rings are the most wear-resistant rings available on the planet.
• Tungsten carbide is about 10 times harder than 18K gold, 5 times harder than tool steel and 4 times harder than titanium.
• Tungsten carbide measures between 8.5 and 9.5 on the Mohs hardness scale, diamonds are 10 — the highest. Due to their extreme hardness, tungsten carbide rings will hold their shape and shine longer than any ring on the market.
• Tungsten carbide rings are impossible to bend or dent, extremely difficult to scratch, and they will never lose its mirror-shiny polish. If a certain pressure is applied to the ring, it will be shattered to pieces.

How to care for tungsten rings:
• Do not drop your ring on a hard surface, such as tile or granite.
• Do not clean your tungsten ring in a jeweler's ultrasonic or ionic cleaner, it could cause a microscopic cracks.
• Do not clean your tungsten ring with any chemicals, as this can cause corrosion spots.
• Try to avoid contact of your ring with household chemicals, as well as prolonged and regular contact with salty seawater.
• Clean your tungsten ring with a mild soap and water. This will remove any dirt and will keep your ring shiny clean.

NOTE: Despite the high hardness of tungsten carbide, do not try to test it yourself for durability. If the ring is damaged due to such tests, the warranty for it will be voided. Also keep in mind that the plating on tungsten rings does not have the same hardness as tungsten itself, and as any plating, will wear off over time, exposing the true color of tungsten.

Important facts about high-tech ceramics:
• High-tech ceramic is heavier than titanium, but lighter than tungsten carbide.
• High-tech ceramic has a lifetime polish and scratch resistance, just as tungsten carbide.
• High-tech ceramic is completely hypoallergenic as well as tungsten carbide, so wearing ceramic jewelry is completely safe.
