Color Sandstone

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” x 4” x 1/3"

  • 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.

The white shows stains too easily

I have a grey set of coasters in Naples that I love so I purchased a white set. The white stone shows stains too easily and I am sanding the surface most every time a guest used them. Great look though when they are clean!

Great product

I bought the coasters because I needed ones that absorb a lot of condensation. Light weight. Five stars except (2) of (4) came with small chips on edge.

Hi Heather,
Thank you for letting us know that 2 of the coasters arrived damaged. One of our customer support representatives will reach out to help with replacements.

Perfect minimalist drying rack

We were tired of moldy drying racks that take too much space and found Dorai! It works for a family if 5! We love it

Works exactly as advertised

These coasters are so cool. It's wonderful to have neither the coaster sticking to the glass, nor a puddle of water running off the sides of the coaster. They are such a great product that I plan to buy them for family Christmas presents.
