Review on 🌟 AMOYSTONE Irregular Quartz Coasters for Drinks: Elegant & Functional by David Stewart

3 of 4 Mug sized coasters. There's one that's a bit awkwardly shaped and too small for a cup to sit on. The polished sides are very smooth and have a beautiful sheen. I like corners and edges, but I wouldn't recommend them for real wood tables. I'm afraid to put them on my solid wood dining table because the edges are pretty rough and I'm afraid they will scratch the wood. I use them on a table when it has a few scratches. Make a cute statement stand. Would have given 5 stars if the coasters were a little more consistent in size.
