Measurements: 4.5x4.25", .5" tall. We made this Coaster from a fieldstone that we hand-gathered at the farm listed above. Artisans sawed and polished the rock with diamond tools in our Lowell, MA studio. Now you can use this artwork as bucolic household accents or to absorb condensation around your favorite cold beverage. The stone is also a trivet for hot dishes, or use as a resting place for a candle, plant, or other treasure. Each stone�s farm-provenance and artisan is permanently labeled on the underside.
