October's birthstone is Opal. Opal is a gemstone characterized by its beautiful variety of colors, and its brilliance and reflection of light are unique.

Opal is a mineral whose main component is silica (silicon dioxide), and the tiny silica spheres inside scatter and refract light, creating a variety of colors. Opals come in a wide variety of hues, sometimes displaying rainbow-like plays of light or fiery brilliance.

Opal has been worshiped as a magical stone since ancient times. Represented by many cultures as a symbol of good luck and creativity, wearing opals is believed to bring inspiration and emotional stability.

Opal is a relatively soft gemstone and must be handled with care. Although it requires proper care and protection, beautiful opal jewelry is popular as a special piece of jewelry.

Opals are available in various shapes and cuts in the jewelry market. The quality of opals is evaluated based on the vividness of the color, luster, and sharpness of the pattern.
