SKU: EB822


A Very Rare Art Deco 1920s Natural Boulder Opal & Diamond Platinum Ring

The centre bezel set with the most remarkable 1.55ct pear-shaped boulder opal displaying magical play-of-colour with flashes of fiery reds, electric blues, vivid greens and yellows, the outer frame set with sparkly diamonds, to a plain polished shank, crafted in platinum.

Boulder opal was discovered in the 1870s in Western Queensland. Today, it is considered the second rarest opal in the world after Black Opal. It is formed along side another rock known as Ironstone. The Opal fields of Queensland produce most of this type of Opal. The amazing thing to notice with Boulder Opal is the presence of remarkable red ironstone within the Opal.
