Can sapphires be artificially made?
Lab created sapphire means a sapphire gem that was grown in a lab, as compared with mined from the ground.

How do you grow sapphire crystals?
We use extreme temperatures and pressure to take powdered aluminum oxide, which is sapphire in its raw form, heat it to a molten state then cool it to solidify in a crystal form. The sapphire expands over three weeks in a huge 6-by-6-foot furnace, then the cooling process makes or breaks the crystal.

In comparison to natural sapphires, lab created sapphires are also less expensive. Natural sapphires demand a high price as they are rare and difficult to mine and involve labour cost as well. Lab created sapphires are easy to make and comparatively more affordable.
Why are lab-created sapphires so cheap?
Because lab-created stones rely on a steady, controlled process of applying minerals, heat and pressure, they usually have fewer inclusions. So you get high-quality lab-created stones, and their prices are significantly lower than their natural gemstone counterparts.
What gives sapphire its blue?
The intense blue of the sapphire is caused by the addition of titanium and iron to the mineral corundum. Sapphires are described by their colors (blue, green, and yellow), with the most sought-after color being cornflower blue. The color is very stable, even when exposed to light and heat.
