"Where" or "were"?
Either way... they aren't or weren't made in caves.
The Lab Created Ruby was first made in the late 1800s by scientists trying to replicate the natural formation of rubies. They discovered a way to grow rubies in a laboratory setting using the same mineral composition as natural rubies, resulting in the creation of lab-created rubies.
Rubies are made of the mineral corundum, which is composed of aluminum oxide with the element chromium giving the gemstone its red color. The intensity and shade of red in rubies can vary based on the amount of chromium present in the crystal structure. Inclusions of other minerals or elements can also affect the ruby's appearance and value.
Synthetic rubies are created in a lab using similar chemical components as natural rubies, but they are made under controlled conditions and typically have fewer inclusions. This often results in a more uniform color and higher clarity compared to natural rubies. Additionally, natural rubies are formed in the earth's crust over millions of years, while synthetic rubies are created in a matter of weeks.
God I hope so
100% of rubies are corundum. "Ruby" is a name made up by the gem trade for the mineral known as corundum, when it is red.
No, they are natural sea-caves and arches.
caves are made of rock
It is a strand of rubies
its made of rubies and it covers lens DUHHHH
Yes. Rubies can be produced in controlled settings.

Rubies are a gemstone. Unless the cat is wearing a collar that is decorated with rubies, no cats do not have rubies.
