Rough Rock, Slabs and Lapidary Materials
BRAZILIAN AGATE (large). Whole nodules of between 0.35kg and 1kg (0.75lb to 2.2lb).
Like most agates, you don't know what's inside until you open them. The examples in the photograph below are typical of this batch.
I've cut some really nice slabs from this material but I've also cut one or two that are solid quartz.
