Silver gilt opal tennis hotsell bracelet

Sterling silver that has been gold plated
Set with oval boulder opals hotsell
The opals are good lively colour,but not the top quality.
But then I'm not asking top price.
I suspect it came from one of the tv shopping channels,although the only mark is 925 on the clasp.
I have tested it for silver and real opal .
Boulder opals are brown on the back , it's the boulder they are found on, left in place for strength.
In excellent condition
