Sapphire & opal pendant in 18ct yellow gold

Unusual Ethiopian opal weighing 15.17ct which is so beautiful on both sides that we decided to set it in a swivel setting so that the wearer can choose which side to have front facing, depending on their preference as to colour. One side is very red, the other blue/green. Set with a 4.8mm round natural blue sapphire weighing 0.62ct. Both stones are rubover set in 18ct yellow gold. The pendant measures 48mm long and is 18mm wide. It is suspended from an 18” trace chain in 18ct which is available for separate purchase for £305.
