Knitting Diva makes handblown glass knitting needles and crochet hooks.

Judy Grill's latest line of needles feature double freshwater-pearl tops which adorn Holz and Stein ebony needles crafted in Germany from residual wood used in making musical instruments like violas and cellos. KnitKnack also has rhinestone, glass, silver, jeweled, cinnabar... You have to check them out! I have a case of the "I-wants"!

I also see that Pony has some rosewood needles. The Pony Total Knitting System is a must-have! Circular, protectors and row counter all together. Good idea!

Of course, I love bamboo needles. They are nice and light and I do find they are easy to knit with. You can see Crystal Palace's needles at Straw.com. (they also have free knitting patterns!!!) I'd love to try out some bamboo crochet hooks.
