Libyan Desert Glass - SOLD 2.450" dendrite with sizes ranging from pebble-sizedComet impact glass! 28,500,000 years old! In the southeastern spur of North Africas Great Sand Sea, there are several fields of luminous, yellow green glass known as Libyan Desert Glass (LDG). Due to the lack of any visible impact crater, the most likely source is a low density asteroid or comet airburst explosion leading to the fusion of silica rich sands roughly 28,500,000 years ago.
