Long Amethyst Geode--"The Tunnel"
Minas Gerais, Brazil
Geodes such as this large display specimen are formed in volcanic vugs (lava hardened around gas bubbles), which arose early in Earth's history. Over time, mineral-laden water seeping into the voids promoted the growth of the crystals which line the interior. A small, natural perforation at the far end of the specimen recalls the saying "to see the light at the end of the tunnel". Measuring 23 1/4 x 18 1/2 x 15in
