Specially cut piece of turquoise

Hi all, I have gotten a bracelet for repair. It was purchased in the
southwest and has 10 turquoise cabs approximately 1x6mm. One of the
stones has been lost. I’ve never seen a stone like this but the
bracelet has a great deal of sentimental value for the customer and
I would like to help. If anyone can cut a stone like this please
contact me directly. Thanks,
