I've just noticed that mine and my children's birthstones are opal, emerald and amethyst (suffragette colours). Does anyone have recommendations for a jeweller who could do me something tasteful with all three stones in yellow gold, thinking maybe a necklace? Google is showing me either very cheap or incredibly expensive options - ideally I'm looking to spend around a few hundred.
Or is this a terrible idea? I'm worried it could turn out a bit tacky.
I've attached a photo of my engagement ring to give an idea of my taste.
