This refers to a gemstone, chemically and optically identical to its mined counterpart, but produced in a controlled laboratory environment. Corundum, the mineral species, is crystallized using methods like flame fusion or hydrothermal synthesis, resulting in a blue-colored sapphire. The resulting material exhibits the same hardness, refractive index, and specific gravity as natural sapphires.
The creation of these gemstones offers a more sustainable and ethical alternative to traditional mining practices. It provides a consistent supply of high-quality material, free from the inclusions and imperfections often found in naturally occurring stones. This consistency allows for greater precision in jewelry design and manufacturing. Furthermore, the reproducible nature of the process allows for controlled coloration and fewer environmental concerns.
