Step 1

Wet the stone surface and spray it with a mild, liquid-based soap to help loosen any buildup from water or pet use. Using an abrasive sponge or cleaning brush, scrub the surface in small circular motions to lift residue and refresh the stone’s natural texture. Rinse thoroughly with clean water, and repeat as needed until the surface looks clean and even.

Step 2

For stains or discoloration, dampen the area and lightly sand it with a medium-grit sandpaper in a well-ventilated space. This will smooth the surface and restore the stone’s quick-drying, odor-resistant qualities. Allow the stone to dry completely before using it again.

My Stone Coaster Set Review

Love love the stone coaster set...keeps my chest of draws top and dining room table dry. Aesthetically pleasing as it has a premium look and love the color (you get 4 in the box); 10/10. Would highly recommend if you're looking to incorporate diatomaceous earth in to your home.

Coasters

Beautiful love the asymmetrical soft edges and color however they stain. We’ve only used them for water glasses so it’s odd they have stain marks.

Coasters that are the perfect resolution for sweating glasses!

I’m hooked on this whole concept of the diatomaceous mats, etc.
The idea works so well! You just don’t realize how much water you end up soaking up with a towel even on a coaster.

Functional and elegant

We love our new coasters! My husband drinks ice water that creates a lot of condensation. I found these while looking for a coaster that would better protect our tables. It is insane how quickly moisture evaporates from the coaster! They are also beautiful. Sturdy without being heavy. Their aesthetic would compliment many decor styles. 10/10 recommend!

Nice shape, great function!

These coaster have proved themselves immediately. I always have a glass of ice water at my disposal and it would sweat my former coasters into a puddly mess. These coasters are fabulous!

Phenomenal absorbent coaster, just needs ONE improvement for perfection

I already had Thirstystone coasters, which are going for about $22 now for a set of four coasters. They are made of natural sandstone. I love BOTH of these coasters. Both work well. The Thirstystone coasters do not work as well as the Dorai coasters, though they DO work well. If you have a tall glass of ice cold liquid and let it sit until it all melts, the Thirstystone coaster WILL have a puddle of water on the coaster, but it doesn't actually get onto the surface below (which is pretty much the most important part of using a coaster). The Dorai coasters work VERY well, but compared to the Thirstystone coasters it is harder to pick them up and move them. This is because the Dorai coasters are much flatter, and the Thirstystone coasters have a cork layer below that makes it easier to grip the coaster.

If the Dorai coasters had something below to provide this seamless grip, then they would be PERFECT. Honestly, if I hadn't had these Thirstystone coasters, then I might've thought the Dorai coasters were already the best they could be.

I like the product but it came in damged

The mat that I got came with a dent. Sounds like you guys went through rough time with distributors, and I sympathize. However I think it is part of your responsibility to deliver full, non-damaged product. I do support your idea and design though, so that’s why it’s three stars.

Hey Mari - we reached out via email to get a replacement mat sent your way! Apologies it arrived with a dent and appreciate your patience as we work with different carriers to best deliver the products in perfect condition. Thanks for the support and keep an eye out for our email :)

Great Product

My coffee table and desk are now ring free. I really like this product as well as the bath mat. I could've gone with a 3rd party brand when it came to "diatomaceous earth" products, but I didn't want to take that risk. I'm glad I spent the extra money for quality.

Smart looking and absorbent

I ordered a set of 4 coasters and they are good looking and keep the moisture contained in the stone. If you’ve ever had a coaster cling to the glass and then fall as you lift the glass, you will appreciate these.

Best absorbing coaster's

I just bought a brand new table from West Elm and wanted to make sure I had a protective coaster that would prevent any liquid’s from ruining it. After trying multiple coasters I stumbled across these ones and gave them a shot. They are absolutely worth it! They soak up any dripping water/liquids unlike other brands I have tried where the liquids just pool on the coaster and then spills over the edge and onto your surface. Wish I had found them years ago. Fantastic purchase!

fabulously looking and functional!

Long a fan of softer coasters but with a new dog, learned a non-chewable option ideal. These are game changers. While long accustomed to leakage, these soak up like a dry sponge.

The Perfect Coaster

My old coasters (over 10 years+) had stopped absorbing the moisture. Hate the water rolling off coasters. Was just not finding what I wanted in stores or online. You know when you find something you like you will wait it out till the perfect solution comes around. I saw these on Facebook and thought they were the closest thing to what I had, take a chance. So far, they have not disappointed. Very attractive and absorbing the moisture. I mentioned this company to friends and I recommend it.
