Luck of the cut

How much more did you take off of it to hit that?

Really nice job!
Agree that it looks like a completely different rock now

Could someone explain what I'm seeing? Is it an enhydro you recut and found druze? Is the bubble still intact?

the water lines are the flat lines. The first cut was in them and was parallel. Which made it appear the agate had no banding.

Yes, aDave, you said that well! Thank you! And, thank you fishnpinball.

Thank you for your video!!!  That really helped me see how "luck" aka experience and knowledge, worked for you. I bet you just knew, maybe without realizing it, that the stone was hiding something beautiful. I haven't even cut 1 stone - the workshed is still under construction- and I have all sorts of questions about how to read stones and know where to cut. I read this forum and other groups and am trying to learn by osmosis. Your video was perfect!

That is a great one.

Reading the finished image using information from the first.

This started as a gas (probably H²O) bubble rising through molten basalt, stopping as the basalt cooled.
steam condensed, dripped down the sides and formed a small pool on the floor and a vacuum in the chamber.

MANY years later moisture began entering through tiny fractures in the surrounding basalt. note the debris that fell from the sides and littered the bottom of the void.

High ph (basic) dissolves silica. Low ph (acidic) causes silica to precipitate - in the first stage as waterline agate/opal.

Later volcanic action reheated the area driving hot silica water into the chamber forming (fortification agate) alternating layers of moganite and chalcedony to stick to all surfaces.

The remaining space reached the temperature point where quartz crystals could form, Then spheroids (probably crystobalite) formed in the remaining open space.

Note the melted points of the last quartz crystals.
