I have been cutting nodules that I have picked up from various small collections. These are a few I decided to polish. Moctezuma Agate - this is a nice little nodule. It has nice banding and a parallax effect.  Laguna Agate - nice pseudomorphs, banding, druse center and parallax effect.  Woodward Ranch Plume Agate - nice well defined plumes and several small fortifications.  Condor Agate - fractured one but this shows how well these polish.  Condor Agate - Red, yellow, lavender, with a druse interior and a parallax effext.  Aragonite pseudomorph replaced by Coyamito - this is a great little agate. Soft red, white and pastel blue, nice banding and parallax effect.  |

The orange and yellow fortification is from a Moroccan Seam Agate I started slabbing last night. I finished slabbing it today and will post some slab photos tomorrow. There are some really nice fortifications in them. |

Those are really great.
Please define "parallax effect".
I'm familiar with the term in ballistics usage. Not in lapidary...

Not a super great video, but you can see the effect. I have one of these, they are cool!
