The details.
Black on the outside and blue on the inside, this 8mm tungsten carbide band is a men's ring for anyone who wants a dark look with a hidden flash of color. The brushed satin surface stays matte, and the blue interior shows only when the ring comes off.
Why people choose it
A colored inner band is a private detail that only the wearer sees most of the time. Tungsten carbide resists scratches from daily wear, and its weight gives the ring a solid feel that many men prefer. The wide 8mm profile gives the black finish plenty of presence, and the brushed texture helps hide light marks from daily wear.
Details
- Material: black tungsten carbide
- Width: 8mm
- Finish: brushed satin
- Inner band: blue
- Interior: comfort fit
- Sizing: offered in 23 US sizes; tungsten cannot be resized
Who it suits
A good choice as a wedding band, a birthday gift or a ring for a fan of blue. Tungsten does not flex, so swap to a silicone ring for work where a ring could catch.
Delivery
Every order is sent with tracking. In-stock orders are usually dispatched within 1–2 business days (Monday to Friday). Delivery time depends on your country. Prices are in US dollars.

My husbands survived everything he threw at it, losing it at a servo and then finding it again 2 weeks later, obviously run over many times. Dropped on slate tiles and somehow didn't break, dropped in an industrial mixer and mixed into pizza dough. Got nicked on something one day, not sure what and it still survived another 6 months without breaking before he lost it for good

I ordered a ring in a size I thought I was without thinking. Ring arrived within a 48hr period and was way to big. Ring came with a sizer which I used to find my correct sizing. I emailed customer service to see if I could rectify my mistake, they where prompt helpful and professional in response and I was able to send ring back in replacement for smaller size without any drama. Ring is solid and high quality. Highly recommended

After wearing a ring for so long, my finger felt naked without one while my existing one was off getting fixed. .. .so I had heard through a friend that Men’s Rings Online has some decent rings that look good even after manual labor. .. .so thought as I’m opposite to that, it surely would suit any occasion and by all means this ring has impressed me! And the price and service was amazing!

2017-08-20
Love the ring and the process to purchase it! Will shop at MensRingsOnline. com. au again! :)
2017-08-11
Patient, helpful and very responsive- one the best personalized experiences I ever had! I ordered a ring for my boyfriend and (because I'm bad at math) I got the size wrong twice (do note that MensRingsOnline did give me direct advice as how to measure ring size, I am just forgetful and was in a rush). But they were very patient with me, were efficient and reduced the stress. I would like to put in that it would be quite helpful if the ring sizer came with an advice about what unit of measurement it followed (for example, the units on the plastic ring sizer is to follow the US size chart on their website); The mistake I made was measuring the finger, rolling it out and then measuring it in mm, comparing the results with the chart on the website.
But all in all, would definitely recommend and buy again in the future! Just follow the US size on the site!

The ring and is great thanks. Looks exactly as the picture online. Delivery was really quick. I'm fairly confident the size is correct, although it is a gift so won't know until the end of February. And because it is wrapped, I can't send you a photo, sorry.
2017-01-29
This site is amazing. Your service is faultless and the ring is perfect. No shop had my size had to wait 4-6 weeks for them to get it re-sized and you guys sent me my ring in my size in 2 days of ordering it and it was better then any ring I came across. Definitely recommend this site To everyone big range, good quality and fast free service.

The new ring in the smaller size is perfect!
It fits my Fiancée so comfortably and it looks gorgeous!
Thank you so much for the support through the exchange process and making it so easy and stress free!
And a rating out of 5 would be a 5, there is nothing I can fault you on in any way, I was seriously surprised as to how smooth, easy and stress free the whole process was.
Thank you again.
I wish you all the best for the business in years to come.
