Types of Opal
The world of opal is vast, with many unique names to describe its various forms. Have you ever wondered why terms like fire opal, black opal, or boulder opal exist? There’s a fascinating logic behind these names that reflect their characteristics and origins. This section will guide you through the enchanting vocabulary of opal types, illustrated with stunning images to bring these terms to life. Let’s explore!
Main Categories of Opal
1. Precious Opal
Precious opal is renowned for its dazzling play-of-color, showcasing vibrant flashes of yellow, orange, green, blue, red, or purple. This phenomenon makes it a coveted gemstone.
Its value is determined by color intensity, pattern, and visibility from different angles. Though rare, precious opal is mainly mined in Australia, with other sources including Ethiopia, Mexico, and Brazil.
2. Common Opal
Common opal lacks the play-of-color seen in precious opal, giving it a more understated appearance. Despite this, it can still exhibit attractive colors and be polished into beautiful gemstones.
Common opal is found worldwide and is often used in jewelry for its subtle beauty.
3. Fire Opal
Fire opal, typically from Mexico, is known for its vibrant yellow, orange, or red body color. While it might not always display play-of-color, its fiery hues are striking and desirable.
Some fire opals do show a play-of-color, earning them the name “precious fire opal.”
Opal Classification by Host Rock
1. Solid Opal (type 1)
Solid opal refers to opal stones that consist entirely of opal material, without any significant inclusions or host rock. This can include both precious and common opal.
2. Boulder Opal (type 2)
Boulder opal includes precious opal within its host rock, often forming in seams and fractures.
The contrast between the opal and the host rock can create striking visual effects, making boulder opals highly valued.
3. Matrix Opal (type 3)
Matrix opal is where precious opal is intimately mixed with the parent rock. Found in both sedimentary and igneous rocks, matrix opal offers a unique and beautiful appearance, with famous sources including Andamooka in Australia and various locations in Honduras.
Opal Classification by Base Color
1. White Opal or Light Opal
White or light opal has a white, yellow, or cream body color and is the most common type found, especially in early Australian mines.
2. Black Opal or Dark Opal
Black opal features a dark body color, which enhances its play-of-color. Highly prized and primarily sourced from Lightning Ridge in Australia, black opals are among the most valuable opals.
3. Crystal Opal
Crystal opal is transparent to semi-transparent and displays a vibrant play-of-color. Designers often use these opals in settings that allow light to enhance their colorful display.

So, what gives opals their incredible play-of-color? It all comes down to microscopic silica spheres arranged in a grid-like pattern within the stone.
When light passes through these spheres, it diffracts, creating the rainbow-like display we adore. It’s like nature’s version of a disco ball – who wouldn’t want that?
Metaphysical Properties
Opals are known for their calming properties, easing stress and depression, and helping to center the mind. They are particularly soothing for children and can alleviate nightmares and fears of imaginary friends.
As a protective stone, opal shields against negative thoughts and energies, and can create a “cloak of invisibility” in challenging situations.
Opals resonate with the energies of the Mother Goddess, making them excellent gifts for mothers or mothers-to-be. They help overcome fears related to childbirth and provide emotional support during pregnancy and motherhood.
Opals are also associated with love and passion, enhancing feelings and releasing inhibitions. They are beneficial for creative individuals, especially those working in water-related professions or the arts.

Chakra Healing and Balancing Energy: Different colors of opal can stimulate corresponding chakras, with the play-of-color linking them to the Crown Chakra, infusing the aura with full spectrum Light.
Spiritual Energy: Opals enhance spiritual light in the aura, awaken psychic abilities, and aid in shamanic journeys and past-life regression. They are also used to connect with angelic beings and water spirits.
