These green crystals are olivine. If you were to choose a representative mineral for Earth, this would be a good choice since olivine is the most abundant mineral in Earth's mantle. Over 50% of the planet's subsurface mineral makeup is olivine. In fact, based on its ability to contain water, it is estimated that more water may be dissolved in olivine of the mantle than is contained in Earth's oceans.
- Each specimen jar contains approximately 30 grams of Olivine
My 10 year old son loved the olivine. He loves The Stemcell Science Shop and is ready to visit.
