"The Rock of God" Libyan Desert Glass, often referred to as LDG, is a translucent to opaque yellow-green natural glass that is found scattered across the eastern Sahara Desert in Egypt and Libya. 

This unique glass is believed to have formed about 29 million years ago, during the late Eocene epoch, when a significant meteorite impact occurred in this region. Libyan Desert Glass is a rare and intriguing natural phenomenon with a history dating back thousands of years. It is a type of tektite, which is a form of natural glass that forms when a meteorite strikes the Earth’s surface, melting and vaporizing the surrounding rock, and then solidifying as glass. 

The ancient Egyptians used LDG to create jewelry, beads, and ornaments. They believed it had mystical and protective properties, referring to it as “the rock of god.”

Libyan Desert Glass is generally translucent, allowing some light to pass through. It is an amorphous glass with a disordered atomic arrangement, similar to other types of tektites. Some LDG specimens may contain small, spherical or elongated bubble inclusions, which are remnants of gas or vapor trapped during the glass’s formation. The silica content is responsible for its glassy nature and transparency.
