This is part of the Spoils of the Earth series, and wow do these beauties SPARKLE!:)******** If diamonds are formed deep down in the earth, how do they get to the surface? Volcanoes - that's how. When they erupt, diamonds are thrown out of the top in the lava or are left in the pipe, the central, vertical part of the volcano. So the best place to find diamonds is in the center of an extinct volcano, in a type of rock called kimberlite. Kimberlite is named after the town of Kimberley in South Africa, where diamonds were first mined in the 1870's and some of the world's largest diamonds are still produced today. This bracelet is for WOMEN only. Thank you, and try before you buy!
