Labrodorite: A greyish feldspar with iridescent flashes of greens and blues reflected from within the stone. It has the effect of butterflies' wings. It was used in art nouveau and art deco period jewellery and first came from the coast of Labrador, hence its name.
Amazonite is rarely used in jewellery
The major source, as for so many gemstones, is Sril Lanka, although moonstones also come from madagascar, Burma, India and Tanzania. The madagascan moonstones have a tendency to be golden yellow, as have Burmese stones which also show cat's eye effect, but not as strongly as the chrysoberyl cat's eye. They are always cut en cabachon to show their adularescence
