Need help with value of this large nugget

I recently won a lot from an auction of turquoise and other minerals. This nugget is one piece of about 12 lbs of cleaned up ready to cab nice hard turquoise. It weighs 174 grams (870 carats) and is about 2 1/4" in diameter. It is quite hard, I cannot scratch it with a #6 hardness pick. I could not find my #7, but it Will scratch with a quartz point. I hope the pictures do it justice as it is quite a brilliant blue and gemmy. Don’t know the type it is, looks like blue gem, but that is usually in thinner pieces.

Edited to correct that it will scratch with a quartz point.

You should slice the top and make two big matching cabs, then come up with a price to sell them at

I could probably get 4 big cabs out of it. I need to get a thinner blade. My son has a trim saw but the blade is .063 thick. It wastes too much material
.

I ended up with around 40 pounds of turquoise after going through everything. Plus about 70 pounds of other minerals. They didn’t say how much was in the lot when I bid on it. I expected a couple of pounds, then it arrived, 4 boxes totaling 120 pounds. Enough for me my wife and son to cut for a long time
