How are Tungsten Carbide Rings Made?

Tungsten carbide rings have grown greatly in popularity over the years. They’re one of the few materials that do not bend, tarnish, and are very scratch resistant. 

Unsurprisingly, owners and fans of tungsten carbide jewellery have wondered how these rings are created. 

In this article, we’re going to show you how manufacturers put together these rings and how many of the common problems presented by this material are overcome.

The Moh’s Scale

The Moh’s hardness scale is essential for understanding why tungsten carbide rings are made in the way they are. Tungsten carbide is an extremely hard material. It’s so hard that there’s a risk of it shattering. This is why an additional carbon alloy will be used to balance the material.

Back to the Moh’s hardness scale, this is a measure of hardness used for metals. To give you some perspective, a diamond would have a rating of 10 (the highest rating). 18k gold has a mere rating of 2 on the hardness scale. Tungsten carbide has a rating of eight.

The Ring Blank

To make the ring blank, carbon and tungsten are ground up until they’re both fine powders. This powder is placed into a high pressure environment with dies and moulds, depending on the type of jewelry.

After being pressed into the moulds, they’re fired in a furnace at 6000 degrees Fahrenheit. Oxygen is removed from the furnace to prevent oxygenation of the metals. Now you have a ring blank.

Cutting Up

After the ring blank has been created, the ring will be cut and crafted by hand. This process requires highly precise crystalline diamond tools and various abrasives. Since the material is so hard, it needs a harder material to make the cuts. And one of the only materials that can do this is diamond. This is why these rings are often so expensive.

In total, there are about 30 different steps to create the perfect ring. It’s similar to the way diamonds are cut and polished. There’s not enough space to go through each step here, but there are plenty of videos and guides on how it’s done.

After the master jeweler completes the steps, the ring has been created and now it’s time to polish it up and sell it.


The above process outlines how to make a simple tungsten carbide ring. Inlays of gold, silver, and other metals can be added. This complicates the process and adds additional steps.

Lasers are used if the wearer wants an engraving. Lasers are the only way to get through the tough metal layers and maintain the right level of precision.

Later Changes

The one drawback of tungsten carbide is the fact it can’t be changed once it’s been made. This is why you need to know the size of your ring finger before making the purchase. Once it’s been done, it can’t be resized under any circumstances. This where our lifetime manufacturer’s warranty comes in, which covers accidental damages as well. We also provide a free lifetime size exchanges on every single ring offered at
