Beautiful unique set of THREE AGATE SLICES. Natural, grade A Brazilian Agate, dyed blue. Simply cut from the stone and polished. I personally hand-picked these 3 among hundreds of others to find a complimentary & aesthetically pleasing set. They are each ~4.75" in diameter, which means you can use them for the wine glasses AND the bottle! 🍷(..the tea cup AND the teapot, and so on..) Unlike most puny 3" coasters you find online, these larger ones can be used with more options: beer, coffee, tea.. or as a part of home decor. ** RUBBER BUMPERS NOT INCLUDED *** PLEASE do not lo-ball. These are already at an amazing price for personalization, AND I ALWAYS INCLUDE a FREE HIGH VALUE GIFT!!
