Comfort-fit feel

Comfort fit is standard. Not an upgrade. The product says the interior rounds out the hybrid: carbon on the outside, tungsten in the core, easy on the hand.

Our rings run roughly 30% thinner than the industry standard profile. They sit flush and clear a glove without catching. The width is 8mm. The collection calls carbon fiber the lightest ring we offer. This band is a hybrid, with a tungsten core, so the light line is the carbon outer.

You should not feel a heavy metal band the way a solid tungsten ring feels. The tungsten is the core. The carbon is what the product says you can forget is there.

Everyday wear

F1-grade carbon fiber strands, no weave, around a tungsten carbide core. The collection says this composite is the aerospace-grade material used in Formula 1 cars and fighter jets. It is highly chemical-resistant, uses no cheap resins, and will not fade or yellow.

The carbon collection is for the man who wants carbon as a main ring, or for the gym and the jobsite when a heavy band should stay home. The Centurion is also in the tungsten collection.

The product lists it as hypoallergenic and inert. That is the skin line. It does not add a nickel claim for the core.

Care

Soap and water, then a soft cloth. Carbon fiber here is highly chemical-resistant, uses no cheap resins, and will not fade or yellow. Marks are not a defect. The lifetime warranty covers manufacturing defects, not scratches.

Sizing

These metals do not resize. Measure first. We do not stretch them. The exchange is a swap, not a resize. The Centurion is stocked in Sizes 8 through 12.5, including half sizes.

Measure at the end of the day. Use a ring you already wear, or the $10 ring sizer. It is a plastic zip-tie, not a piece of string. It should pass the knuckle with a little resistance, then sit snug. Between sizes, size up. Wider bands feel tighter.

Wrong size: free exchange for 90 days from delivery. For a surprise gift, the window can start on the wedding date. Send a photo or the date.

What is included

The Centurion includes a free F1 carbon fiber backup. The backup is ultralight and non-conductive, for the gym or the jobsite. The F1 sold on its own does not include a second backup.

The lifetime warranty covers manufacturing defects for the life of the ring. Email info@alpharings.com with your order number and a photo. We review in 3 to 5 business days and repair or replace it free. Not covered: normal wear and scratches, accidents, lost rings, or modifications.

The 90-day size exchange runs from delivery. It is a swap, not a resize and not a refund. For a surprise gift, the window can start on the wedding date. Send a photo or the date.
