Fred,
That piece with the horse portrait is a cab for a pendent. My friend that is an opal dealer gave it to me years ago and I came across it when unpacking all that was in storage.

It is made out of a piece of black stone that most likely had the horse image cut into it with ultrasonics, then opal was inlaid into the image and then a clear cap stone was put on top. It is really pretty amazing next time I am in the studio if I remember I will take a close up image of it and post it.

I plan on making a pendent for my horse freak of a daughter one of these days. We always say the first word out of Lela's mouth was horse. She is now in her early thirties and her and her husband have I think five horses.

One of my joke statements to people. "One of the saddest and happiest days in my life was when Lela moved out. Sad to see her go and very happy to see two horses going with her"

All my best ..... Danny
