Gemstone production process

The process generally is grading, cutting and polishing of gemstones that will be obtained from the land to be leased for this purpose. That is, first the roughs come in small rhyolite geodes filled with opal. Then the individual raw stone is examined (graded) and cut into smaller stones along its major line of fracture and inclusions. The smaller pieces are then mounted on cutting tools, which are then faceted on faceting machines. The final operation involves polishing of the faceted stones. Polished stones are then delivered to the customers or sold to the market.
