Opal Doublet Earrings – Sterling Silver, 31×8mm, Semi-Dark, Dark Blue Flash

At 31 x 8 mm, these are statement earrings — long enough to brush the neck, catching light as they move. The blue flash sits against a semi-dark body that gives the colour genuine contrast: not flat, not too heavy, just dark enough to make the blue read with depth. In motion — turning the head, a shift in light — the flash travels across the stone. In silver, the cool metal keeps pace with the blue rather than competing. Bezel-set at the top, they hang clean and straight. One pair, no two stones like them.

About Opal Doublet

An opal doublet is a thin slice of natural Australian opal cemented to a dark backing — usually ironstone or black potch (the common opal that doesn't carry colour play). Doublets are a legitimate technique used in the opal trade for over a century: solid opal thick enough to cut as a whole stone is rare, so using the precious opal layer efficiently means more people can own genuine Australian opal at a sensible price. The opal itself is the same material you'd find in a solid stone — just used more efficiently — and the dark backing intensifies the colour play above it.

Caring for Your Opal

Opal is softer than diamond or sapphire, and doublets need extra care around water — prolonged exposure can degrade the bond between the opal layer and its backing. See Opal Care for the full routine including doublet-specific notes.
