When in Tucson, I purchased a small supply of the rough of a
relatively new blue chalcedony that comes only from Namibia. As far
as I know it is available from only one mine. It is a much darker
blue than the sky blue of holly blue agate, or any other blue
chalcedony I’ve seen. It is more in the tones of navy or perhaps a
lighter Pacific Ocean blue. I haven’t finished cutting a piece yet
because I’ve been working on other things but I’d be glad to forward
a photo if anyone is interested.
It is definitely a chalcedony and one of the pieces I have is
included with a lighter blue plume. It’s all quite handsome and an
exciting new material for those who like the glowy translucence of
chalcedony and want blue. As I said, I only got a small amount. But
I know I can track down the source. Of course, as one can imagine,
it’s not cheap.
