3-6" Mexican Beach Cobble
Description
3–6″ Mexican Beach Cobble is a great choice for water features, gabion baskets, and bold accent beds because of its smooth, naturally tumbled shape and striking color shift between dry and wet conditions. It's also an excellent choice for residential and commercial xeriscaping projects. With its sage-green and slate-gray base, dusted with white mineral speckling and occasional warm gold-olive stones, this stone brings a cool, sophisticated character that deepens into a rich, glossy slate-green when wet. Whether used as a decorative ground cover, a water feature accent, or gabion fill, 3″–6″ Mexican Beach Cobble delivers striking contrast and lasting performance in virtually any application.
True Sizing Note: Like all Mexican Beach Pebbles, our 3″–6″ designation follows a traditional industry grading scale. In practice, the current inventory in this grade ranges approximately 4″–8″ — so you can expect generously oversized, show-stopping statement stones perfect for bold focal points and dramatic landscaping. We recommend seeing current inventory in person for darkness and sizing, as this line tends to run larger than listed. We keep the sizing labeled to what the supplier and other resellers call it, to stay consistent with how this product is known industry-wide.

Installation Depth Guide — Cubic Yard Coverage for 3″–6″ Mexican Beach Cobble
| Depth | Coverage per Cubic Yard | Recommendation |
|---|---|---|
| 4″ | ~90 sq ft | Too shallow |
| 5″ | ~70 sq ft | Not recommended |
| 6″ | ~60 sq ft | Minimum depth |
| 7″ | ~55 sq ft | Recommended |
| 8″ | ~50 sq ft | Ideal depth |
| 9″ | ~45 sq ft | Usually unnecessary |
| 10″ | ~40 sq ft | Excessive |
Note: Because individual stones in current inventory can measure up to 8″, a typical installation depth is 7-8 inches for this rock — enough to fully bed the largest pieces. Installing shallower than 6 inches will leave larger stones sitting loosely on top of the base rather than nested in, which can cause shifting. Some pieces may fall outside the stated range as part of the natural mix. When in doubt, test a small section first.
Product details, what you should know
- Sizing: Labeled as 3″–6″ per standard industry grading, though current inventory typically runs 4″–8″. Some pieces may fall outside this range as part of the natural mix.
- Cleanliness: Washed, smooth river-tumbled material with minimal fines.
- Appearance: Smooth, rounded stone featuring a cool blend of sage-green and slate-gray, dusted with white mineral speckling and occasional warm gold-olive stones mixed throughout. Colors deepen dramatically and take on a glossy, polished look when wet — dry stones read pale and chalky, while wet stones darken to a rich slate-green. Color may vary slightly between loads.
- History: Material has remained generally consistent in size range and color over time. The sage-green and slate-gray blend with white speckling is typical of this stone, with minor variation between loads as expected with any natural river-tumbled material.
- Also known as: Commonly referred to as Mexican Beach Pebble, MBP, or polished beach cobble.
Mexican Beach Cobble is prized for its dramatic wet/dry color shift — pale, chalky sage-gray when dry, deep glossy slate-green when wet — making it a favorite for water features, dry creek beds, and gabion baskets where that contrast really shows. Its rounded, tumbled shape means it's not recommended for driveways or high-traffic surfaces; it's best suited as a decorative or accent material. Worth noting — because current inventory runs larger than the nominal 3″–6″ label suggests, this material makes an especially bold, sculptural statement piece rather than a fine-textured ground cover.
