About Tungsten Carbide
Tungsten carbide is one of the hardest metals used in jewelry. It's much harder than titanium, gold, or platinum, holds a mirror polish that doesn't dull from daily wear, doesn't bend out of round, and resists scratching from almost anything you'll encounter day-to-day.
The trade-off is that tungsten is harder than it is tough. A direct hammer-strike or a fall onto concrete from height can chip it. In an emergency it can be cracked off the finger with standard ER tools, which is actually a safety advantage compared to gold or platinum.
Tungsten rings don't trigger nickel allergies, don't tarnish, and don't oxidize. The ROKA holds the same finish years into wear as it has on day one.

- 30-day returns from receipt on unworn rings
Sizing & Fit
The ROKA is comfort fit, meaning the inside of the band is rounded rather than flat, which makes it easier to slide over the knuckle and more comfortable for all-day wear. Comfort-fit rings typically size a half-size smaller than standard-fit rings, so if you normally wear a size 10 standard-fit, you'll likely wear a 9.5 in the ROKA.
Available sizes: 4 – 14, including half sizes.
Not sure what size you wear? Use our free ring sizing guide, or order any size and use our lifetime sizing to swap if it doesn't fit perfectly the first time.
Care Instructions
Wipe the ROKA with a soft cloth. That's the core care routine. Tungsten doesn't tarnish, doesn't oxidize, and doesn't lose its polish from daily wear. For a deeper clean, warm water and mild dish soap; rinse, dry, done. Avoid dropping on tile or concrete (tungsten is hard but brittle), and remove for heavy hammer/chisel work.
Engraving
Every ROKA includes free inside laser engraving. Add a wedding date, initials, coordinates, or any phrase up to 30 characters. Engraving is permanent, professionally applied, and does not delay shipping.
Frequently Asked Questions
What color is the ROKA?
The ROKA features black.
What sizes does the ROKA come in?
The ROKA is available in sizes 4 – 14, including half sizes. If you're between sizes, lifetime sizing is included, so you can order, try it, and swap if needed.
Is the ROKA comfort fit?
Yes. The ROKA is comfort fit, meaning the inside of the band is gently rounded so it slides over the knuckle easily and sits flat against the finger. Most wearers find it comfortable enough to forget they're wearing it.
Is the ROKA durable for daily wear?
Tungsten carbide is one of the most scratch-resistant materials used in jewelry, and much harder than gold, titanium, or platinum. The ROKA is highly resistant to scratches from daily wear. It is brittle under sharp impact, so avoid hammer-strikes or drops onto concrete.
Is the ROKA hypoallergenic?
Yes. The ROKA is nickel-free and hypoallergenic, safe for sensitive skin and people with metal allergies.
Can the ROKA be engraved?
Yes. Free inside laser engraving is included with every ROKA. You can add a date, initials, a phrase, or coordinates. Engraving doesn't delay shipping.
What if the ring doesn't fit?
Lifetime sizing is included with every ROKA. If it doesn't fit, ship it back and we'll send a different size, even years after the original purchase.
How long does shipping take?
Free standard shipping ships within 1-2 business days from our Irving, Texas shop and arrives in 3-5 business days within the US. Most ROKA orders arrive within a week of ordering.
What is Aydins' return policy?
See our returns and exchanges page for full details.
Can the ROKA be cut off in an emergency?
Yes. Both tungsten and ceramic rings can be safely removed in an emergency. Hospitals use a tool that cracks the band cleanly off the finger without needing to cut through it. This is actually a safety advantage over gold or platinum, which require more time-consuming cutting.
