Siren Stone Diatomaceous Earth Coasters Set of 4 | Absorbent, Quick Dry, Non-Toxic | BPA-Free | USA Brand

Siren Stone Diatomaceous Earth Coasters — Set of 4

Inspired by the rugged beauty of Lake Superior, the Siren Stone coasters combine natural texture with modern slate tones. This four-piece set features uniquely shaped, organic coasters about 4 inches in diameter. Each piece captures the irregular charm of nature, making every coaster subtly one-of-a-kind. Crafted from premium diatomaceous earth in a sophisticated slate finish, they complement a range of decors—from contemporary to coastal. Note that the coasters have a natural stone bottom with no felt or cork backing; for delicate surfaces, we recommend adding self-adhesive cork pads.

Exceptional Absorbency & Quick Drying

Say goodbye to damp rings and lingering moisture. The porous stone surface is designed to absorb up to about 150% of the coaster’s weight and to evaporate moisture in moments rather than minutes. Expect a fast-drying feel that helps keep tabletops, desks, and bar tops looking clean. The dark slate hue naturally helps conceal minor spots, allowing surfaces to stay visually tidy between wipe-downs.

• Rapid absorption minimizes condensation on furniture
• Fast drying reduces water rings and stickiness

Versatile, Everyday Use

These coasters do more than protect surfaces. They double as heat-resistant trivets (up to 450°F), making them practical for hot coffee pots, teapots, and serving dishes. Their 4-inch footprint fits a wide range of drinkware—wine glasses, cocktails, mugs, tumblers, and stemware—while adding a touch of natural elegance to counters, desks, and bar tops. A four-pack that keeps pace with busy homes and entertaining alike.

• Function as stylish drink safeguards
• Dual-purpose as heat-safe trivets for cookware

Material, Care & Longevity

Made from 100% natural, food-grade diatomaceous earth, the coasters are non-toxic and BPA-free. The slate finish offers a refined look that remains appealing with daily use. Maintenance is simple—rinse and wipe clean without soaking or special cleaners. The durable material maintains its absorbency and appearance through thousands of uses, making these coasters a long-lasting addition to homes and workspaces.
