Irish Bog Oak - Looks better than it sounds

I spotted this in a joblot of jewellery on everybody's favourite auction site. It was hidden amongst some more contemporary jewellery and bought it thinking it may be Jet. However, after much research, a few little tests and hours cleaning and squinting into a loupe I'm pretty sure it's Irish Bog Oak. It cleaned up quite nicely and it does seem to have some age to it. I have seen pictures of similar styles from the Victorian Era and I think this may be from late on in that era after the Queen had started to allow bits of colour back into jewellery on the court ladies. I love it anyway and often wander about the house wearing it, calling out for the ghost of Prince Albert. He hasn't turned up yet, but it amuses Husband, who thinks I look more like one of Macbeth's witches every day with all my bone, and horn, and jet jewellery.
Any input would be appreciated, as ever.
Thanks for looking.
