Wouldn't it be better as to use a copper sulfate solution instead to form the crystals, and also add a decomposition reagent since azurite is formed through the decomposition of copper?
What you got is a sodium copper carbonate probably Na2Cu(Co3)2.x H2O. Sorry to rain on your parade. Azurite even in small crystals is a really dark blue.
Nevermind about cooling it, I tried it and got some blue sand, so I'm assuming it caused the crystals to fall out of solution too quickly and prevented them from growing large, typical me being impatient, oh well hindsight is 20/20
1) Yeah I've tried using one of the crystals as a seed crystal, but it didn't work the 1 time I tried it and I've simply not been patient enough to try again, but I think it probably could work, so give it a try!
2) Yeah typically you get bigger crystals from longer cool-times, so trying to rush it will make more numerous but smaller crystals... hmm... but perhaps insulating the container will slow it down enough to produce bigger crystals? lol
Oh and when you let it sit over night you should try cooling it, it should in theory reduce the waters solubility and result in more or larger crystals.
I wonder, if you prepared another batch of solution could you use one of those crystals you made as a seed crystal to grow one larger crystal? Either way I'm trying it.
Hmm, probably none really. It just makes neat blue crystals. If looking awesome is a use, then I guess that's about it. Oh and it probably also can cure some forms of fish fungus too... but I might just be making that up. Copper sulfate can do that too, but doesn't look nearly as cool.
I believe the leftovers are malchite, a copper ore similar to azurite. I performed this experiment for my school's science fair, and am pleased to announce that my teacher loved it. Thanks for the video!
Did the solution itself at least turn blue? That's the important thing; almost always some sort of blue/green or black crud will form. Might depend on how clean the copper being used is.

Actually, you have Bicarbonate ions (The blue crystals) witch really makes much sense if your mixing it with H2 gas or Na+.

Formula should be Na2Cu(CO32. 3hH2O which occurs as a mineral chalconatrite Reference: Dana's New Mineralogy p 465-6 1997.

Okay I have crystals, but there pretty opaque, almost milky...

Yeah, I redid the experiment with about 200 ml of solution and lots of crystals are forming now. the insulation is a good idea, I'll have to try it.

So, the blue flakes precipitating out of the solution are normal?

what is the use of this substance?

Glad to see it gave you good results! My many ours of random tinkering in my basement has actually done some good in the world. ^_^ lol

When I make this, I got mud-like blue-green leftovers, but in the middle of the electrolysis

(Azurite) Try with KON or NaON instead! There are also other ways.

Nice experiment, i have some Azurite minerals and many other copper minerals.
