Opal is a wealth of diversity in itself. Surprising and mysterious, it offers a play of color like no other stone. Depending on the rock of which it is made and the architecture of its elements, the reflection and subsequent decomposition of light on its surface give rise to opaline reflections that always differ from one stone to another. According to the angle of view, it takes on unique colored flashes.
Whether a common, precious, noble or black opal, the stone comes in a wide variety of more or less abundant specimens worldwide. Instead of shining with a play of colors, the common opal displays a slightly milky white.
Virtually considered a fine stone, precious or noble opal is used in fine jewelry. It lends its luminous flashes to extraordinary items of jewelry. Seen as the “queen of precious stones,” black opal offers intense spectral colors. It has also long adorned the jewelry of the world’s great dynasties. This indescribable stone can produce up to 200 colors in a single gem.
Largely unknown, black opal has real surprises in store for jewelry lovers. Lending itself to spellbinding, unique designs, it will perhaps be the new star of jewelry in the years to come. It is also very expensive.
Opal is mainly sourced from deposits in Australia. It presents a hardness of 5.5 to 6.5 on the Mohs scale.
