Review on 🌿 DUQGUHO Decorative Rocks Aquarium Gravel: Natural Fluorite Chip Bulk Pebbles for Plants, Terrariums, and Fish Tanks - 0.44 lbs by Brenda Garvin

I used them for a garden project so I didn't need the same sizes. If you plan on using them for jewelry or anything else where they need to be roughly the same size, this probably isn't for you. The stones ranged from about 5mm x 5mm to 10mm x 20mm. Thickness also varied widely, from pieces 1 or 2mm thick to small stones 5mm thick. The assortment is very similar to that in the photo, where they are held with two hands. I received about the same number of stones of about the same quality. All in all they will look very cute in the pot I put them in and will make the plant stand out nicely.
