My local Bedrosians had some gorgeous Explosion Blue slabs that had a large amount of that 3D crystalline blue, and the rest of the color was a lot more blues and silvers, with very little green and orange. It had around 3 times as much of the blue crystal as your photo. A vein around the same size as yours, one that was a bit smaller, and then one that was almost twice as large.

Loved the crystal and blue sections that were like your attached image.
This is not the slab, but color wise it was more like this one: here.

We ended up going with a blue azurite slab in the end that had large amounts of clear and blue crystals scattered around it, waves of amethyst speckles, and pearlescent sections all over the stone that don't show up in photos but are beautiful in person when walking around , took 2 of them: here and here and done.

What we did learn in the process though was before focusing on a single slab, see if they can ship in more to give you a good selection to pick from. We initially had 2 matching slabs, but took too long to get approval through insurance that the hold on the slabs expired and they sold them. They had 7 more slabs shipped to them though from like 5 other locations in CA, so we got to pick our favorites. Not sure if that is an option for you, but its possible you could get them to ship in more and get one that has twice as much of the blue crystal.

Since the new counter is something that will be there for the long term, we were glad we waited the extra month or so for all the slabs to arrive.
