Australia
An unusual type of transparent, yellow labradorite feldspar occurs in the Hogarth Range, New South Wales, and the Springsure area, Queensland. Large, clear gemstones can be faceted from this material. Care is needed when cutting and handling because of its two directions of perfect cleavage. Hardness is 6 - 6.5.
