Natural Agate Coasters Set of 4, Dyed Purple 3-3.5" Geode Slices for Small Cups & Glassware, Unique Crystal Stone Decor with Rubber Bumpers

Polished and lovely. They look great on my table

Really like these. Nice quality

These are really beautiful, but if you’re drinking a cold drink with ice, the condensation will make the coaster stick to the glass. I use them for hot beverages.

Only reason I am giving 4/5 is I wish they were bigger. My mason jars hang off the sides lol

I've gotten agate coasters in the past because I like the look of them, but had the issue where they were clearly dyed and started staining things when they got wet. I'm happy to report that these don't have that issue at all. I also appreciate the little buttons they come with that you can put on the bottom so they have better traction. I would definitely buy these again but I don't think I'll need to any time soon because they seem to be good quality and are sturdy coasters.

I bought this coaster set as a Christmas gift. They are such beautiful slices of agate, I was tempted to order a second set for myself! They are perfectly flat so they probably won't catch excess condensation but hey, this is gorgeous, functional natural art!

Beautiful purple agate! They are not as see-through as you may think and are very vibrant. They do ship with small little plastic feet dots that you can stick on the coaster which is helpful. The only complaint that I have is they are cut different sizes and the smallest one does not fit a regular sized cup to protect my table, but I am still happy with my purchase
