Philippinites, or rizalites are tektites found in the Philippines. They are considered to be about 710,000 years old on the average[1] and generally ranging in size from millimeters to centimeters.[2] Their age corresponds with the age of other tektites in the Australian strewn tektite field.[1] In 1964, a very large philippinite, weighing 226.3 grams (0.499 pounds) with dimensions 6.5 x 6.2 x 5.2 cm, was purchased by the University of California, Los Angeles Department of Astronomy.[3][4] The heaviest philippinite ever found weighs 1,281.89 grams (2.8261 pounds) in its splash-form[Note 1], which is also the heaviest tektite of this kind.[5]
