Opal Facts

Opal Origins

Opals are primarily found in Australia, where they were first discovered in the 19th century. Australia is renowned for producing the finest quality opals, including the highly prized black opal, crystal opal, and white opal. However, opals can also be found in other countries such as Ethiopia, Brazil, Mexico, and the United States.

A Symphony of Colors

One of the most captivating features of opals is their mesmerizing play-of-color. These gemstones exhibit a dazzling array of hues, ranging from fiery reds and vibrant oranges to serene blues and vivid greens. Opals showcase a unique combination of colors that seem to dance and shift as they catch the light, creating a truly enchanting spectacle.

Types of Opals

Opals can be classified into various types based on their appearance and formation. The most common types include white opal, which displays a light background color with delicate play-of-color, and black opal, characterized by a dark body tone with vibrant play-of-color. Other types include crystal opal, boulder opal, fire opal, and matrix opal, each possessing its own distinct beauty.

Opal’s Water Content

Unlike most gemstones, opals contain a significant amount of water. On average, opals have a water content ranging from 3% to 21%. This water content contributes to their unique play-of-color, as the interplay between light and the microscopic spheres of silica causes the colors to shimmer and change.

Opals have been associated with various symbolic meanings throughout history. They are often regarded as symbols of hope, purity, and love. Opals are also believed to enhance creativity and inspire imagination. In ancient times, opals were treasured for their supposed mystical properties, and they were believed to bring good fortune to their wearers.

Birthstone of October

Opal holds the distinction of being the birthstone for those born in October. As a birthstone, opal is believed to bring luck, happiness, and positive energy to individuals born during this month. It is a popular choice for jewelry pieces given as October birthday gifts or anniversary presents.

Opal’s Optical Phenomenon

Opals exhibit a captivating optical phenomenon known as “play-of-color.” This phenomenon occurs when light interacts with the internal structure of the opal, causing the diffraction and interference of light waves. The result is a stunning display of spectral colors that seem to shift and change as the gemstone is viewed from different angles.

Opal’s Healing Properties

Opals are often associated with various healing properties. They are believed to promote emotional healing, enhance intuition, and foster a sense of calmness and balance. Opals are also thought to aid in the healing of ailments related to the eyes and improve overall eye health.

Opals require special care to preserve their beauty and durability. They are relatively soft gemstones, ranking around 5.5 to 6.5 on the Mohs scale of hardness. To protect opals from scratches and damage, it is recommended to store them separately from other jewelry and avoid exposing them to extreme temperature changes or harsh chemicals. Regular cleaning with a soft cloth and mild detergent is advised to maintain their lustrous appearance.
