Our minimal coasters do more than eliminate watermarks—they dry instantly! Created with diatomaceous earth, Dorai’s River Rock and Slate Coasters are both sustainable and designed to rapidly remove moisture.

Each cup coaster is a different shape and pattern, emulating the unique, natural qualities of stones. The River Rock Coaster Set includes four coasters that pair perfectly with a beverage of your choice.

Dimensions: 4 in x 4 in x 1/3 in

  • Made with eco-friendly, non-toxic, and long-lasting materials.
  • Dries instantly thanks to Diomat®, our sustainable combination of diatomaceous earth and recycled paper.
  • Helps prevent bacteria growth by eliminating the moist environment where mold thrives.
  • Functional design created for the modern home.
  • This product is made from compressed diatomaceous earth and recycled paper, so white spots and slight color variation occur naturally in the production process.

Cleaning Instructions: If your stone gets stained, it can be cleaned in two ways. For light stains or scuffs use the included sanding tool to gently rub off any marks. We recommend doing the sanding in a well ventilated area. For more extreme stains, use a small amount of hydrogen peroxide or bleach to treat the area.

They work!

These coasters look great, work well to absorb condensation and are lightweight! From the website you might think they are a heavier stone. We also have the bath mat which we love! Wish it all came in more colors!


Works like the promo materials. Quick driving stone, much better than a damp mat.

the stone coasters were a gift for my son along with the stone bath mat. He was very excited about receiving both of them.

Elegant coasters

These coasters were the most beautiful things I have ever seen. The sea life decorations are minimal yet stand out. And as advertised, any water or liquid condensation from glasses or cups are absorbed instantly without any worry of having to wipe away later.

Thirsty Stone Coaster Perfection

I have been looking for a coaster for years and none have done what this has accomplished. I don’t have a wet coaster mess on my table, damp napkin or a coaster that sticks to my glass just enough time to fall off and crash on the floor. So far these have worked like magic.
