Useful questions

Before requesting 3/4 Black Lava Rock

Are price and availability confirmed?

The published price was verified on Rio’s public site on October 21, 2026, but that is not proof of physical stock. Rio must confirm variant, quantity, current price, availability, and timing.

How do I calculate a useful quantity?

Will the material match the photo?

Do not assume it will. Review the image-truth label, caption, and any credit. Natural materials and current lots can vary; request a current-lot check or sample when appearance is decisive.
