SK Cobalt is a new production of men's lifestyle wedding bands by Scott Kay. It is created from BioBlu™ 27, the world's most superior contemporary metal, used for the first time in jewelry. This luxurious exotic alloy is unparalleled in strength and durability, extremely white, scratch resistant, and entirely hypoallergenic. SK Cobalt is proudly created, engineered, and designed 100% in the United States of America.

No wedding band should ever be at risk of breaking, cracking, or shattering.

As seen under 4000 power magnification, a solid material is created when it is brought to a 100% homogeneous molten state and then cooled. This eliminates any possibility of it fracturing or chipping. Tungsten Carbide is ground to a powder, compressed, and held together by a nickel binder. This forms a non-solid cemented carbide, thus explaining why a material so hard can also be unexpectedly brittle.

Q: What is BioBlu™ 27?
A: BioBlu™ 27 is an alloy developed by Carpenter Technologies. It is created by melting raw natural elements into a homogeneous liquid state, which is then cooled into a 100% solid form. It has been used in various other applications due to its superior strength and durability, but is being introduced for the very first time in the use of jewelry.

Q: Is it safe? I have seen some conflicting cobalt information on the internet.
A: Cobalt is an element that exists naturally throughout the world. BioBlu™ 27 is a patented alloy that combines cobalt with other natural elements to produce a hypoallergenic, entirely safe, and bio-compatible medical grade metal.

Q: If it is so hard and scratch resistant, can it be cut and removed?
A: Yes, there are tools that can successfully cut and safely remove an SK Cobalt band.

Q: Where can I find the SK Cobalt™ collection?
A: Ask your local Scott Kay retailer if they carry SK Cobalt. To find a retailer nearest you, search our map.

Q: How do you remove a BioBlu 27 or Cobalt band?
A: With a diamond-plated cutting disk. Please see this instructional video on the safe removal process.

SK Cobalt™/BioBlu™ 27 is formed by melting raw materials into a homogeneous liquid state, followed by cooling into a solid form. BioBlu™ 27 is manufactured by Carpenter Technology Corporation. This process, similar to that for platinum, palladium and gold jewelry, allows for durability, wearability, and extraordinary resistence to shock and pressure. While being five times harder than platinum, it is not brittle and will maintain its solid integrity throughout the life of every design. BioBlu™ 27 is a pending U.S. trademark of CRS Holdings, Inc., a subsidiary of Carpenter Technology Corporation.
