Ancient Bog Oak is the oldest timber on the planet. Before petrification, timber goes through many stages; dying, falling, and drying. Before this ancient bog oak reached the "drying" stage, it was covered with lichen and moss to blot out the sun/elements and suspend it's return to the earth. It laid in a bog for around 6,000 years (it's patina is the darkest I've ever seen) and was discovered in the western Czech Republic after WW2.

All timber is sealed in a vacuum with marine grade epoxy to insure utmost strength and durability of a design. This ring consists of a sandblasted gunmetal dark gray Tungsten Carbide band with an ancient Bog Oak interior.

Specs:
Band Width: 8 mm
Band Thickness: Circa 1.8 mm

Customer photo review of The Prehistoric Oak

The “ancient bog oak broke and came out of the interior of the ring literally on my wedding day as I was placing the wedding band on to my husbands finger this past Saturday June 6th on our wedding day. 😫😭

Although first ring received didn’t fit, it was quickly exchanged with professionalism. Love the unique look of the textured tungsten and, coupled with the bog wood, it’s definitely a conversation waiting to happen.

Customer photo review of The Prehistoric Oak

My husband wanted a ring that was unique and didn't look like every other ring, which is exactly what this is! It still looks very "manly," but it isn't the traditional solid black ring. It is hard to describe, but it is a mix of black, brown, and grey, with a really cool charcoal-looking finish. The oak on the inside is also such a unique touch. He loves it. The company also has amazing customer service and was very quick to fix a mistake on their end. I would highly recommend!

Customer photo review of The Prehistoric Oak

Highly recommend!! My fiancé and I both love this ring! It’s manly and beautiful and exactly what we wanted. We originally ordered a size to small and exchanged for the corrected size for only a small restocking fee. Long story short we lost the original ring): Thorum customer service was so great at responding so quickly and shipping back to back was very fast. We are so grateful for the help and they were so nice!

Customer photo review of The Prehistoric Oak

Really like the look and feel of this ring. I lost my platinum band and this was a great replacement. It is unique. No one else can see the inner wood but I like wearing a piece of wood that is several thousand years old. Reminds me that in the big picture our life is brief.

The Prehistoric Oak

Ring itself seems well made a has a nice feel to it. I was a bit disappointed at how dark the wood is, because it’s significantly darker than the stock photo, its actually black in color. But in the item description it does say its quite dark, so I cant say I was misled. The rubber ring replacement that comes with it was a size or two too large and slips off my finger without any friction or resistance but I bought the ring for the ring, not the rubber replacement. Overall I am happy with the ring

The Prehistoric Oak

The ring was exactly what I was looking for. Great quality, comfortable on my finger and seamless service from picking it out to delivery. Very pleased with Thorum!

The Prehistoric Oak

My Fiance loves the prehistoric oak ring! It’s sleek, earthy, and looks great on. The costumer service was a breeze when the first size wasn’t the right fit. We would recommend to any future groom!

The Prehistoric Oak

I was sent the wrong style and wrong size ring. It's been challenging to reach customer service to get the correct ring.

The Prehistoric Oak

Store owner replied: Hi Emily, thanks so much for taking the time to leave a review. It looks like we responded to your original inquiry that same day as well as shipped out the correct ring - so it does look like this was taken care of. We are so sorry for any troubles that you experienced and are always here to help if you need anything else. :)

We had to exchange the ring for a different size twice (due to mistakes on our part) and the process was smooth and easy. My fiance loves his ring!

The Prehistoric Oak

The Prehistoric Oak

Really loving my new ring. Great quality, perfect fit, sleek design, and not clunky/heavy like my previous ring. Highest of recommendations!

My fiancé loves his ring. We ordered the ring sizer beforehand and the fit we went with was perfect. Good quality and fast delivery made this a great experience.

The Prehistoric Oak

It came in and I’m in love! I can’t wait to propose to my boyfriend on our trip in a couple of weeks!

The Prehistoric Oak

Store owner replied: YAY! We cant wait either, we hope you'll share photos with us :) Congrats!!

We aren’t married yet but he was very happy about finding something that was unique and not metallic looking. It’s gonna look great on his finger!

The Prehistoric Oak

Beautiful ring! We ordered the ring sizer first and both of them arrived quickly

The Prehistoric Oak

The ring is beautiful. Hasn’t been worn yet, so I can’t attest to durability.

The Prehistoric Oak

The ring is beautiful, he loves it! We ended up having to resize and the company made the process super quick, and easy.

The Prehistoric Oak

He loves it! Will note that the wood on the inside is darker than what is pictured on the website (this likely differs ring to ring), so there isn’t as much of a contrast between inside and outside. The exterior is a little shimmery.

The Prehistoric Oak

Awesome craftsmanship. Fits amazing. Super fast shipping. Thank you!

The Prehistoric Oak

As advertised. Very pleased with the quality feel and style.

The Prehistoric Oak

The Prehistoric Oak

My future husband loves this ring and how unique it is! Very high quality! I definitely recommend getting the ring sizer before purchasing!

The Prehistoric Oak

I bought this ring to propose to my girlfriend. I haven’t done it yet, but I’m sure she’ll love it. The unique materials and craftsmanship has already impressed me.

The Prehistoric Oak

Love the ring, we were looking for something more unique and this ring definitely didn’t disappoint. Beautiful craftsmanship. Would recommend!
