First heart shape I saw down at the Tucson shows, and it is a slice from a giant geode, not even amethyst crystals. This was outside lining the gallery at Mineral City. Large enough and heavy enough it needed an ironwork stand. It was raised up to eye level. Last geode post on “theme” for today. ❤️

We’re here! One entrance line from ramp parking. Sooo many people from around the world. So many ages too! #Chalcedony #Specimen #Mineral #Crystals #Tucson #TucsonGemMineralShow

Ah, another grape chalcedony specimen! I’m celebrating because in half an hour we are setting off on another rockin’ day adventure. To the world’s largest gem and mineral show, Tucson.

This is the first convention center showcase I’ve been to in about 6 years. And when I saw “we”, my son John agreed to come which means Drew gets to come too, with his wheelchair. So, a family adventure today, our “day-cation” 118 miles south. To do this, we have to have both I and John push Drew and wangle the 3 of us around thousands of people in the enormous center. We leave very early in hopes we can score accessible parking. This is EPIC!

This is how one of my iPhone photos looks on Flickr in one of my albums. Sometimes I wait a while befor I stare at an iPhone photo to see if I want to monkey with it a bit more in editing. I try really hard to present a photo in a faithful photo with true color as I saw it in the moment I took the photo. It’s mighty tempting to boost the color because over the years I see more and more people doing this. The saturation is too deep or contrast too sharp. Landscapes are tricky because so many use HDR to heighten a fantasy appearance far more magical than reality. Or maybe I’m just not validating when someone else is seeing the image super pumped up as their own reality. #MyPhoto #MyPhotography #iPhone #Chalcedony #Rock

Rocking out again. I worked myself into a purple haze this morning staring at all the amethyst and grape chalcedony photos I got, mostly at the Marcus Budil gallery at Tucson Gem & Mineral show venues at Mineral City. I edit them to appear as I saw them, I think “true to life”.

Here are a few and a lot will just go into my Flickr album so @theropologist doesn’t get rattled by a heavy load on the beige party server! Reminds me I want to pass on another donation to the server funds—recommending donations go to support your own servers!

Eye #Agate is a rare gemstone distinguished by its unique patterns resembling eyes. These "eye-like" formations are created by concentric layers of minerals—such as #chalcedony, #quartz, and occasionally #jasper—that form circular or elliptical bands

Eye #agate, a captivating gemstone, is named for its mesmerizing patterns that resemble eyes. These "eyes" are formed by alternating layers of differently colored #minerals, such as #chalcedony, #quartz, and #jasper

#Carnelian is a form of #chalcedony whose amber, brown, and even green hues are caused by inclusions of iron oxide and other #silicate #minerals.
Carnelian is another form of #silicondioxide besides quartz.

A lot happening in this geode fragment, including tiny quartz crystals & lace agate. #rocks #chalcedony

@[email protected] @Aznorth @stux This is based on:

* Obviously, colour (#jasper is just "any red #chalcedony", chalcedony being semiprecious #flint/#chert - that is, cryptocrystaline #quartz)

* Availability in large sizes

* #Conchoidal fracture

* Brittle

Obviously I can't do any more tests than that from here!

A fine agate
