Opal Doublet Pendant – Sterling Silver, Red & Blue Multicolour Flash

A gem-quality doublet — Joseph's own assessment, and he doesn't use that phrase lightly. This 27 × 12 mm stone carries dominant red fire with strong secondary blue rolling across a multicolour field, the colour bright and unambiguous even indoors. The opal is bezel-set in sterling silver and hangs on a solid sterling silver chain at 45 cm — long enough to rest just at the collarbone, short enough to sit close rather than drift. At $1,850 this is one of the more significant pieces in the doublet range, priced for what it actually is: a large, vivid, hand-selected stone that Joseph pulled from the fields himself.

About Opal Doublets

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, and they exist for one good reason: solid opal thick enough to cut as a whole stone is rare, and using the precious opal layer efficiently means more people can own genuine Australian opal at a price that makes sense.

The opal in this piece is real, natural Australian opal — the same material you'd find in a solid stone, just used more efficiently. The dark backing serves the same function as the dark body tone in a black opal: it acts as a backdrop that intensifies the colour play above it. Visually, a good doublet can rival a solid stone for fire and brilliance — the difference is in the construction, not the opal itself.

Caring for Your Opal Doublet

Opals are softer than diamonds or sapphires, so a little care keeps yours brilliant for generations. Doublets need one extra precaution that solid opals don't: avoid prolonged water exposure, as it can degrade the cement bond between the opal layer and the backing.

• Avoid knocks and hard impacts — store separately, ideally in a soft pouch or lined box
• Avoid prolonged water exposure — no swimming, no showering, dry off if it gets wet
• Keep away from extreme heat or sudden temperature changes
• Never use ultrasonic cleaners, steam cleaners, or harsh chemical cleaners
• Clean gently with a soft, slightly damp cloth — no detergents, no alcohol
• Remove before gardening or anything rough

Treated well, your doublet will hold its colour for decades.
