Whazitcalled?

I made a necklace with some really pretty stone beads I bought. They were labeled lapis, but I don't think so, unless they're a lower grade. They have a lot of white in them for lapis lazuli, and no gold flecks either. And, the coloring is more blue-grey than a true lapis blue. I'm thinking the beads are either sodalite or even dyed howlite, because of the veining. I really want to list this necklace in my Etsy shop, but I need to have an accurate description. I'm a bead-lady, not really a gemstone expert, so any help would be appreciated! THANKS! Linda
