Dagan 6 to 12 Inch Lava Rock - 30 Pound Box

We are sorry, but we do not offer lava rock in individually selected or guaranteed sizes. Our lava rock is sold in bags or boxes containing pieces within a stated size range, rather than pieces chosen to specific dimensions. The closest match to what you are describing is our Dagan 6 to 12 Inch Lava Rock - 30 Pound Box, which contains natural volcanic rock pieces generally ranging from 6 to 12 inches. However, we cannot guarantee that any particular piece will measure 10 or more inches in length with a 6 to 8 inch diameter, as the pieces vary naturally in size and shape. For lava rock cut or selected to those exact dimensions, we recommend checking with a local specialty stone or landscaping supplier.

We understand you are looking for three very large black lava stones, each over 12 inches in size, and that the Dagan 6 to 12 Inch Lava Rock you previously purchased was not large enough. Unfortunately, we do not currently offer individual lava stones of that specific size. Our lava rock products are sold in boxes or bags containing pieces within a specified size range, and we do not have pieces that consistently measure 12 inches or larger. The largest pieces we typically carry range from 4 to 6 inches. For lava stones of the specific dimensions and individual nature you are seeking, we recommend checking with local specialty stores or landscaping suppliers, as they may be able to assist you with finding individual pieces cut to your exact specifications.

The Dagan 6 to 12 Inch Lava Rock is natural volcanic rock sourced from natural volcanic deposits in the Western United States. However, the exact quarry or specific mountain origin is not detailed in the product information.

These lava rocks are made of natural volcanic rock and are intended to enhance the flame appearance in fireplaces and fire pits. While they are effective at conducting and distributing heat, the product information does not explicitly state whether they will glow red when heated. However, lava rocks, in general, tend to exhibit a red glow when heated to sufficient temperatures due to the oxidation of iron content. This glow is a result of their high temperature.
