OPAL
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.
Presque considérée comme une pierre fine, l’opale précieuse ou noble est utilisée en joaillerie. Elle prête ses éclairs lumineux à des bijoux hors du commun.
Tenue comme la « reine des pierres précieuses », l’opale noire offre des couleurs spectrales intenses. Elle a d’ailleurs longtemps orné les joyaux de grandes dynasties du monde. Indescriptible, cette pierre peut produire jusqu’à 200 couleurs dans une seule gemme.
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.
