Small Opal Necklace

• 12mm long setting with synthetic opal in 16kt gold plate
• Charm is tarnish resistant
• Your choice of 18kt gold ion bond over stainless steel cable chain that closes with a lobster claw. Or a 14kt gold filled cable chain that closes with a spring ring clasp (all rings and findings will be 14kt gold filled) - both are non tarnish but gold filled is a lighter gold
• I suggest an 18 inch chain
