Synthetic corundum, which includes both rubies and sapphires, holds significant value in the gemstone market due to its durability, brilliance, and affordability compared to natural stones. Its creation through controlled processes allows for larger, flawless specimens that can be sold at lower prices than their natural counterparts. Additionally, the increasing demand for ethically sourced and conflict-free gemstones boosts the appeal of synthetic corundum. Overall, while it may not have the same prestige as natural stones, its value lies in its accessibility and environmental considerations.

How is corundum made?
Corundum is a naturally occurring mineral composed of aluminum oxide (Al₂O₃) and can form through various geological processes. It typically crystallizes under high-pressure and high-temperature conditions within metamorphic rocks or as a result of the cooling of magma. Additionally, synthetic corundum can be produced in laboratories through methods like the Verneuil process or the Czochralski process, where aluminum oxide is melted and allowed to crystallize. These processes create both natural and synthetic forms of corundum, which includes gemstones like sapphires and rubies.
What is the plural of corundum?
Corundum.
Which crystal system does corundum have?
Corundum is in the trigonal crystal system.
What is the only mineral that can scratch corundum?
Diamond is the hardest mineral and is the only one that can scratch corundum. but in my opinion corundum will scratch corundum any mineral of the same hardness will scratch the other !
Can quartz scratch corundum?
According to the Mohs scale of mineral hardness, quartz (7) will not scratch any mineral with a higher number on the scale. Corundum is listed at 9. Therefore quartz will not scratch corundum, but corundum can scratch quartz.
What is the value of corundum?
The value of the mineral corundum will vary according to its appearance. Gem quality corundum is highly valued. Non gem quality corundum has many industrial uses and is much less highly valued.

What is corundum used for?
Corundum is primarily used as an abrasive material in industries for cutting, grinding, and polishing. It is also used in the production of refractory materials, such as fire bricks and furnace linings, due to its high heat resistance. Additionally, corundum is the main ingredient in the production of synthetic gemstones like sapphires and rubies.

How do you make synthetic corundum?
There are several different methods, your best bet would be to expose powdered aluminum and a small bit of chromium to the open flame of a blow torch. You may need to use something hotter, as the heat required to fuse the powered aluminum to the chromium is around two thousand degrees Celsius. You can buy synthetic boules of corundum online for pennies a carat. As product of the chatum method, there are now synthetic crystals on the market, in the form of hexagonal/water worn crystal pieces. The best of luck.
