Libyan Desert Glass- The Sun Stone
Eastern Saharan Desert- Libya/Egypt
Welcome to the world of Libyan Desert Glass, an ancient stone of sun and desert, revered by the Egyptians and prized by both collectors and metaphysicists alike. A stone like that may happen only once in a planet’s lifetime- the perfect combination of cosmic forces and desert wisdom.
Geology and Formation
Libyan Desert Glass is a true impactite formed roughly 29 million years ago as a result of a large meteor which struck and fused with Saharan sand in a highly energetic and explosively infernal cataclysmic event. Known as the Stone of the Sun, or Desert Glass, it has the highest silica content (95.6-99 wt% SiO2) of any stone on earth, and contains Zirconium Oxide (ZrO2)- which can only occur at temperatures above 2,250°C- owing to its unique ability to refract the sun’s light very powerfully. Libyan Desert Glass is derived from the combined composition of the meteor that struck the mature Saharan sandstone and kaolinite, and characteristically contains high concentrations of pure silicate minerals such as reidite, cristobalite and lechatelierite. Epochs of erosion from wind-blown sand and dunes shaped the smooth edges of any exposed stones- likened to the smooth edges of modern-day seaglass- while buried surfaces maintained the regmaglypts and crater-like surface texture present from the original creation event. For this reason, each piece is unique in texture, shape, color, inclusion, etc. It is found over an unforgiving 130x50km² stretch of the Saharan Desert between Libya and Egypt.
Definitive proof of a meteoritic impact creation event is evident in the presence of reidite microcrystals, which is a high-pressure form of zircon that can only form at immense pressure (Cavosie & Koeberl, 2019). Researchers suggest the impact event reached 100-megaton potential- an event that occurs only once every 10,000 years. Other notable attributes of the desert glass include a particularly high water content (0.64%), high viscosity, and high amounts of high-pressure quartz inclusions, with a low refractive index (1.4616) and specific gravity (2.21).
It is still a mystery how the desert glass may have cooled so fast as to create instant homogenous fusion and relatively bubble-free liquid that would have rapidly cooled to create glass without any inclusions. Even commercial human-made glass takes many hours to relieve the melt of its volatile components and cool fully, yet, the desert glass contains no partially melted material or target rock inclusions, suggesting it cooled very quickly and homogenously.
History, Mythology and Uses
The ancient Pharoah King Tutenkhamen was notably discovered in his tomb with a giant carved scarab beetle around his neck carved out of Libyan Desert Glass, suggesting the stone was sacred and revered by the ancient Egyptians and their Gods. The Pyramids of Gyza, The Sun Temple of Apollo, and the Libyan Desert Glass strewn field create a nearly perfect equilateral triangle that also intersects significant sun-enriched electromagnetic leylines, which many consider the world’s “Sun Triangle”.
It has been postulated (without significant evidence) that the Desert Glass was created during an immense solar flash, which might explain its remarkably high silica content, obvious solar resemblance and energy, high refractive index, and the lack of an observed impact crater in the Saharan region (which may also be due to the shifting dune sands and lack of intensive LIDAR or geophysical research in the area).
The stone is found in the shifting Saharan desert dunes between Egypt and Libya, and has been hard to source recently because of political instability in the region and difficulty making collecting trips through the vast and unforgiving desert. It is a light stone generally associated with the solar plexus, offering a more soothing energy than other tektite species.
