How can you tell good quality moonstone?

A good moonstone should be almost transparent and as free of inclusions as possible. Inclusions can potentially interfere with the adularescence. Characteristic inclusions in moonstone include tiny tension cracks called centipedes. They are called this because they resemble those long, thin creatures with many legs.
