Inclusions (internal cracks, black spots, etc.) can be seen depending on the grain. [Bonus column: Sapphire is the navel of the world] Sapphire is a mineral species called corundum and is composed of aluminum and oxygen. It exists in igneous rocks and metamorphic rocks that do not contain silicon. Have you ever played in the schoolyard looking for transparent sand or pebbles when you were a child? That is silicon. Since silicon is evenly distributed in the earth's crust, there are very few crustal environments without silicon, and they are limited to metamorphic zones of ultra-high temperature and high pressure. That is the center of Gondwana, a supercontinent that existed about 700 to 500 million years ago. The Gondwana continent was a supercontinent at that time, and in its center, an ultra-high-pressure metamorphic zone where most of the continents that exist today collided was formed, creating the conditions for the formation of corundum (sapphire) with a hardness of 9 on the Mohs scale. Africa's Mozambique, Sri Lanka, Madagascar, and the continents of India all converged in one place, and metamorphic sapphires (and other volcanic sapphires) formed in the middle of these unusual environments. Rather than saying that sapphires are produced in various places, sapphires were produced in one place and then spread throughout the world. Sapphire is a proof that it is the former "navel of the earth". Collecting sapphires is as romantic as collecting pieces of the earth. Since the earth's crustal energy has declined since 700 million years ago, an event like the formation of the Gondwana supercontinent may be a once-in-a-lifetime event. The heartbeat of the earth is hidden in one beautiful small sapphire.
