Help to ID a fire opal silver pendant

I would like to know the silversmith who created this triangular fire opal pendant. The maker’s mark on the back is MW. How do I transmit photos of the pendant?

When you are typing a message in order to create a post…look at the bottom right hand corner of the textbox and below it is a blue word that says UPLOAD just touch that and it should prompt you to pick the spot where your photos are and then you just pick a photo from there and once you find the photo by following those prompts you touch it and it will amazingly get attached to your post…once you see your photo attached then you can hit reply in the bottom left-hand corner and your post should appear with your photo!

Good luck!
