Dagan 6 to 12 Inch Lava Rock - 30 Pound Box

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.

Per the manufacturer, it is sold by weight. They estimate between 2 and 4 rocks, depending on the weight.
