The Darwin impact event is generally placed at approximately 816,000 years ago. Unlike tektites that travelled through the atmosphere and landed far from their source, Darwin Glass is generally classified as an impact glass \/ impactite associated with the local crater environment.\u003c\/p\u003e\n\u003cp\u003eNatural Darwin Glass can range from translucent to opaque, with dark green, charcoal, brown and olive tones.
