Australian Opal Doublet
An opal doublet is a beautiful, budget friendly composite gemstone engineered by bonding a thin slice of real Australian precious opal onto a dark, protective backing. This dark base absorbs light, artificially intensifying the play of color to mirror the look of a premium Lightning Ridge black opal at a fraction of the cost. Opal Galaxy focuses exclusively on doublets made with natural backing materials like boulder ironstone.

 Understanding Opal Doublet Construction and Care
Opal doublets are genuine composite gemstones. The top layer is a slice of real precious opal, usually sliced from crystal or white opal mined in fields like Coober Pedy. The bottom layer is a dark, supportive backing like Queensland ironstone or black opal potch, which artificially enhances the play of color. This construction makes the thin opal slice durable enough for secure setting in jewelry.
While doublets offer excellent visual appeal, they require specific care.20 Because they are assembled using a high strength adhesive, they must not be submerged in water or exposed to harsh cleaning chemicals, which could cause the glue to fail and separate the layers. They are highly recommended for use in pendants and earrings where they are protected from hard knocks. To review terms of sale, please visit the Opal Galaxy returns and refunds page.
