Limestone fits a lot of projects, from décor to gardening. On this page you'll find options sized for different jobs.

• Landscaping: Accent beds, borders, pathways, and around water features.
• Planters & décor: Vase fillers, succulent pots, bonsai, and terrariums.
• Aquariums: Selected pebbles can create natural-looking scapes; rinse before use.
• Classroom & hobby: Rock specimens for teaching and collections.
• Soil amendment: Pulverized or pelletized limestone can help raise soil pH and add calcium.

Choose size by task: smaller pebbles settle between plants; larger stones stand out in beds. You can filter by "Decorative Stones" or "Landscaping" and check weights to match the project. Pickup and delivery options may be available in checkout.

A few simple clues can help you spot limestone using household items.

• Look: Many limestones are light gray, tan, or white and can appear smooth to slightly chalky.
• Fossils: Small shell or coral fragments are common in sedimentary limestone.
• Vinegar test: A drop of white vinegar may fizz or bubble on limestone because of calcium carbonate. Dolostone, which also appears here, tends to react more weakly.

Visual comparisons with educational specimens (like oolitic or raw limestone) can be helpful. Reactions vary by composition, so use these checks as indicators rather than definitive proof. If you're using stones in aquariums or gardens, rinse them and confirm they're suitable for your setup before placing.

Expect a few normal changes when limestone is exposed to water.

• Appearance: Decorative pebbles often darken temporarily and return to their lighter tone as they dry.
• Surface: Freshly wet stones can be slick; take care on walkways.
• Chemistry: In aquariums or soil, limestone may slowly release calcium carbonate, which can raise pH and hardness. Monitoring water or soil levels helps keep conditions where you want them.
• Forms of limestone: Pelletized or pulverized products are made to dissolve more readily as soil amendments.

Rinsing stones before installation can reduce dust. Effects vary by stone size and composition, so checking your environment after placement is a good practice.

Several well-known rocks form from or relate to limestone.

• Marble: Metamorphosed limestone that recrystallizes under heat and pressure, producing a denser, often brighter stone.
• Travertine: A type of limestone deposited from mineral-rich waters, commonly used decoratively.
• Dolostone: Forms when magnesium-rich fluids alter limestone, creating a similar-looking sedimentary rock with different chemistry.

You'll see decorative versions of these materials and classroom specimens on this page. Each has distinct textures and uses, from landscaping to teaching. If you’re matching a specific look or need (like a lighter color or a particular grain), check the size ranges and descriptions to pick the right stone for your project.

Both amend soil, but they behave differently.

• Pelletized limestone: Small granules designed for easy spreading with less dust. They typically break down with moisture, offering gradual contact with the soil.
• Pulverized limestone: A fine powder that makes faster contact when mixed in, but it can be dusty and is often blended directly into beds or garden soil.

Choosing one depends on where you’re applying and your equipment. A soil test can help you decide how much to use. Spread evenly and water in when appropriate. Application rates and timing vary by product and conditions, so follow label directions and monitor pH over time. Pickup and delivery options may be available at checkout.
