Who the BOSULU is for
The BOSULU 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 gorgeous black ceramic and wood inlay style from our wood inlay rings line is made using the hardest ceramic and the finest authentic African Padauk wood inlay. This design creates an elegant balance between new world metal and traditional wood, which has been used in jewelry making for centuries. Padauk wood is also used to manufacture of musical instruments and even used as medicine.
- This comfort-fit band has beveled edges and comes in 6 mm, 8 mm and 10 mm for couples who prefer a matching set.
- This is the perfect wedding band to represent your love and commitment.
- Truly Free Lifetime Sizing and Lifetime Warranty on all tungsten rings, no exchange|sizing fees, which are charged by our competitors.

About Black Ceramic
Black ceramic is a high-tech engineered material. It's harder than steel, lighter than tungsten, and the color is permanent. Unlike black-coated metal rings (PVD or IP plating) that wear off at the edges over time, the BOSULU's black goes all the way through. It won't fade, chip color, or develop bare patches.
Ceramic is highly scratch-resistant but brittle under sharp impact. Drop it on a hard surface and it can chip. The flip side: in an emergency, ceramic rings can be cracked off the finger quickly with standard ER tools.
Black ceramic is hypoallergenic (no nickel), holds its mirror finish without polishing, and is noticeably lighter on the finger than tungsten. The BOSULU stays glossy with a soft cloth, no jeweler's polish required.
About the Koa Wood Inlay
Koa is a Hawaiian hardwood, historically reserved for royalty and now grown on managed forest land in Hawaii. The BOSULU'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 BOSULU 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 BOSULU 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 BOSULU.
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
The BOSULU's black ceramic is color-stable for life, with no plating to wear off and no need for refinishing. Wipe with a soft cloth for daily clean, warm soapy water for deeper buildup. Avoid drops on tile or concrete (ceramic is hard but brittle) and skip abrasive cleaners.
Engraving
Every BOSULU 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 BOSULU?
The BOSULU features black with a real koa wood inlay.
What sizes does the BOSULU come in?
The BOSULU is available in sizes 4 – 15, including half sizes. If you're between sizes, lifetime sizing is included, so you can order, try it, and swap if needed.
What width is the BOSULU?
The BOSULU is offered in 6 & 8 & 10mm widths. Both widths are available so couples can match their bands.
Is the BOSULU comfort fit?
Yes. The BOSULU 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 BOSULU durable for daily wear?
Black ceramic is highly scratch-resistant and the color goes all the way through, so it doesn't wear off the way coated black rings do. The BOSULU stays glossy for life with minimal care, though ceramic can chip if dropped on hard surfaces.
Is the BOSULU hypoallergenic?
Yes. The BOSULU is nickel-free and hypoallergenic, safe for sensitive skin and people with metal allergies.
Can the BOSULU be engraved?
Yes. Free inside laser engraving is included with every BOSULU. You can add a date, initials, a phrase, or coordinates. Engraving doesn't delay shipping.
Is the koa wood inlay real?

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 BOSULU orders arrive within a week of ordering.
What is Aydins' return policy?
See our returns and exchanges page for full details.
Can the BOSULU 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.
