Darwinite or Darwin Glass was created over 800,000 years ago in the Mount Darwin area of Tasmania.

Like Moldavite, it is believed to have been created by the impact of a meteor hitting Earth.
Darwinite varies in colour with a few being almost white, through greens and browns to black.

I only came across Darwinite recently. Although it has transformative properties, I find it much less intense than Moldavite. Although it has a high frequency energy, I find that it has a strong resonance with the spirit of Earth and of the natural word. It is heart centred and helps us to know our place on Earth.
