One name I could think of off the top of my head is Rab Gordon. He's mainly known for his excellent Sgian Dhus, but also makes jewelry.

I have bookmarked a couple of other great sites on my home laptop, but that's not available to me at the moment. I'm sure you'll get some other great suggestions and I'll log on later in the day once I track down the other links.
