Roostertail Agate was never mined on a large scale. So, there isn’t much of this beautiful agate slabs available on the market. We bought this material many years ago and recently uncovered it in our storage. Roostertail Agate is nice and solid and has bright colors and fabulous figuring.
As with all of the other species in the quartz family, agate takes a high polish with cerium oxide, but also takes a fine polish with tin oxide and diamond. Mohs hardness 7.
