The mineral olivine is a magnesium iron silicate with the chemical formula (Mg,Fe)₂SiO₄. It is a type of nesosilicate or orthosilicate. The primary component of the Earth's upper mantle, it is a common mineral in Earth's subsurface, but weathers quickly on the surface. For this reason, olivine has been proposed as a good candidate for accelerated weathering to sequester carbon dioxide from the Earth's oceans and atmosphere, as part of climate change mitigation. Olivine also has many other historical uses, such as the gemstone peridot, as well as industrial applications like metalworking processes.

ओलीवाइन या चन्द्रकान्त जो कि रत्न स्तर के होने पर जबरज़द कहलाता है, एक खनिज है। यह The mineral olivine (also called chrysolite and, when gem-quality, peridot) is a मैग्नेशियम लौह सिलिकेट है जिसका रसायन सूत्र है: (Mg,Fe)₂SiO₄। यह पृथ्वी पर सर्वाधिक सामान्य खनिज है, एवं उल्का पिंड (टूटता तारा) में भी पाया जात है।
