Faceted Opals: A Kaleidoscope of Color and Brilliance

What Is a Faceted Opal?

A faceted opal is a gemstone that has been cut and polished into a geometric shape, such as a round brilliant, square, or emerald cut. This process enhances the opal's play-of-color, the iridescent and dynamic display of colors that is characteristic of opals. Faceted opals are used in a wide range of jewelry, from rings and pendants to earrings and necklaces.

How Are Faceted Opals Cut?

Facet cutting is a specialized technique that requires great skill and precision. The opal is first cut into a rough shape, which is then carefully shaped and polished using a variety of tools, including diamond-coated saws and polishing wheels. The cutter must consider the opal's natural characteristics, such as its hardness and transparency, in order to create the best possible cut.

Benefits of Faceted Opals

Faceted opals offer a number of benefits over their uncut counterparts, including:

• Enhanced play-of-color
• Increased brilliance
• Greater durability
• Easier to set in jewelry

There are a variety of different types of faceted opals available, each with its own unique appearance and characteristics. Some of the most popular types include:

• Black Opals: These opals are characterized by their dark body color, which ranges from gray to black. They display a vibrant play-of-color that can include all the colors of the rainbow.
• White Opals: These opals have a light body color, which can range from white to cream. They display a more subtle play-of-color than black opals, but they are still very beautiful.
• Boulder Opals: These opals are formed when opal fills in the cavities of ironstone. They have a unique appearance that includes patches of opal surrounded by ironstone. Boulder opals can display a wide range of play-of-color.
