Are you an aquarium or terrarium enthusiast, or know someone who is? This set
was put together to outfit a medium size tank. It includes 12 black / dark gray
rocks, ranging from 2½"-over 4" on their longest axis. You'll see a variety of
pockmarking types and unique crevices - in the right setting, one or two would
make excellent lava walls or towers. Also known as “scoria” or “cinder”, they
were hand-picked directly from the Springerville Volcanic Field, near the White
Mountains of east-central Arizona.
Those pockmarks are scoria's most recognizable feature. When they were
expelled from volcanoes that were active here over a half million years ago,
hot gases were captured within the molten lava and trapped as it cooled,
leaving thousands of tiny "pores" within the rock itself.
Lava rocks are ideal for use in aquariums and terrariums. They make
exceptional bases for planting succulents and air plants, too! For more
information about why ... and for more information about lava rocks in general
... please visit our blog, with answers to some "Frequently Asked Questions".
We don't take you for granite at Arizona Lava Rocks! Our listings don't start
out in a pile in some yard! Each rock is individually gathered. It was picked
off the ground because something about it caught our eye. Again, this listing
is for the specific rocks you see in the accompanying photos. Our inventory is
constantly changing - please check out our other listings.
