Barium found in the Earth's crust is a mixture of seven primordial nuclides, barium-130, 132, and 134 through 138. Barium-130 undergoes very slow radioactive decay to xenon-130 by double beta plus decay, with a half-life of (0.5–2.7)×10 21 years (about 10 11 times the age of the universe). Its abundance is ≈0.1% that of natural barium.The first diamonds found in South Africa were alluvial and by 1870, a blue, hard, igneous rock, later named kimberlite, was discovered as the primary source of diamonds.
