Opal: The fascinating gemstone with the rainbow effect

Among all gemstones, the opal holds a special position. With its unique play of color, the so-called "opalescence," it has fascinated humankind for millennia. At Sirius Diamant, we particularly appreciate the opal for its individuality – no two stones are alike.

What makes the opal so special?

Unlike many other gemstones, the opal is not a classic crystal, but a silica gel containing water. Its famous sparkle is created by the diffraction of light on microscopic silica spheres. Depending on the arrangement of these spheres, flashes in all colors of the rainbow emerge.

The role of opal in jewelry making

In the world of high-end jewelry, the opal is a symbol of creativity and exclusivity. Due to its relative softness (hardness 5.5 to 6.5 on the Mohs scale), its processing requires the highest level of craftsmanship:

• Unique pieces: Since each color pattern is unique, every piece of jewelry becomes a true one-of-a-kind.
• Combinations: Especially in combination with diamonds and white gold, the fire of the opal comes into its own.
• Popularity: It is the birthstone for the month of October and a popular gift for special anniversaries.

Types of Opals: From White to Black

There are various types of opals used in the jewelry industry. The Black Opal is considered the most valuable, as its dark body allows the colors to shine particularly intensely. The White Opal, on the other hand, appears softer and more elegant.
