Who the CONGO is for
The CONGO carries Hawaiian heritage in its grain. Koa was historically reserved for royalty, and the curl pattern shifts color as the ring catches the light. For grooms drawn to natural materials, surfers, or anyone who wants a ring with warmth that metal alone can't match.
This unique tungsten and wood inlay style from our wood inlay rings line is made from ultra-durable tungsten and beautiful sapele wood. This design creates an elegant combination combining together the most scratch resistant material and the oldest material to be used in jewelry. The inlay is made of authentic African sapele wood, which is an extremely hardwood. Sapele is used to make musical instruments such as guitars.

- This is the perfect wedding band to represent your love and commitment.

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 CONGO holds the same finish years into wear as it has on day one.
About the Koa Wood Inlay
Koa is a Hawaiian hardwood, historically reserved for royalty and now grown on managed forest land in Hawaii. The CONGO's koa wood inlay shows the signature curl and chatoyance the wood is famous for: the grain shifts between honey-gold and deep amber as the ring catches the light, an optical effect from the wood's natural fiber alignment.
Each piece of koa is one-of-a-kind. The grain pattern, color depth, and figure vary across every cut. Koa is dense enough to be durable in a ring inlay but warm enough to take to body temperature instantly, giving the CONGO a distinctive feel that metal-only rings can't match.
Care: koa is real wood. Keep it relatively dry, avoid soaking in pools or hot tubs, and condition the surface every 6-12 months with our included ring oil. With basic upkeep the wood deepens in color over the years rather than fading.

Sizing & Fit
The CONGO 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 CONGO.
Available sizes: 4 – 15, 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 CONGO 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 CONGO 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.

What sizes does the CONGO come in?

What width is the CONGO?
The CONGO is offered in 6 & 8 & 10mm widths. Both widths are available so couples can match their bands.
Is the CONGO comfort fit?
Yes. The CONGO 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 CONGO 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 CONGO is highly resistant to scratches from daily wear. It is brittle under sharp impact, so avoid hammer-strikes or drops onto concrete.
Is the CONGO hypoallergenic?
Yes. The CONGO is nickel-free and hypoallergenic, safe for sensitive skin and people with metal allergies.
Can the CONGO be engraved?
Yes. Free inside laser engraving is included with every CONGO. You can add a date, initials, a phrase, or coordinates. Engraving doesn't delay shipping.

What is Aydins' return policy?
See our returns and exchanges page for full details.
Can the CONGO 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.
