Black opal doublet and diamond ring featuring a 15.2 x 9.2mm oval opal doublet with vibrant blue, red, and green color play, accented by 0.20 carats of diamonds in 14K white gold twisted shank design. Ring size 7.5, adjustable.

This black opal doublet showcases spectacular play-of-color with flashes of electric blue, crimson red, and emerald green across a dark body tone. Measuring 15.2 x 9.2mm, the oval cabochon displays the characteristic color shifts that make opal one of the most captivating gemstones in nature. The doublet construction consists of a natural black opal slice adhered to a dark backing material, a traditional technique that enhances color visibility while providing structural support and making fine opal more accessible than solid specimens. The opal displays broad color patterns with strong saturation.

Opal doublets are created by bonding a thin slice of natural opal to a darker backing, typically black onyx or ironstone. This construction method enhances the opal's color play by providing contrast against a dark base, similar to natural black opal. Doublets offer an affordable alternative to solid black opal while still featuring genuine opal material with authentic play-of-color.
