Raw Libyan Desert Glass Value Guide

Libyan Desert Glass is a rare natural tektite formed 29 million years ago by a high-energy meteorite impact or airburst over the eastern Sahara. This golden-yellow silica glass is highly collectible due to its extraterrestrial origins and its historical significance, famously used in King Tutankhamun's pectoral jewelry.

What Is Raw Libyan Desert Glass Worth?

The typical price range for Raw Libyan Desert Glass is $140 - $155 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Clarity and color intensity, with vibrant golden hues and high transparency commanding higher prices.
• Weight and size, as larger intact specimens are increasingly difficult to source from the Egyptian-Libyan border.
• The presence of dark streaks or cosmic dust inclusions which can increase scientific and collector interest.
• Overall aerodynamic shape and the degree of natural desert polish on the exterior surface.

How to Identify Raw Libyan Desert Glass?

• Look for a characteristic pale yellow to honey-gold translucency unique to silica-rich impact glass.
• Examine the surface for wind-sculpted 'regmaglypts' or pits caused by thousands of years of desert erosion.
• Check for the presence of lechatelierite, which are small, white, high-temperature inclusions of fused quartz.
• Verify the texture; authentic raw specimens have a smooth, waxy feel rather than a sharp, synthetic glass edge.

History of Raw Libyan Desert Glass

Libyan Desert Glass was formed approximately 29 million years ago by the intense heat and pressure of a meteorite impact or airburst over the Sahara Desert. The resulting heat melted the local silica-rich sand into a unique glass. It was used by ancient Egyptians for jewelry, most famously as the scarab centerpiece in Tutankhamun's pectoral.
