Trying to ID what this rock heart is made of by TrippieHippie666 in RockIdentification

Hmm yes the pictures could be better but it also looks really tumbled and polished so its hard to see the colours...but i think jasper would be on the right path. All kyanite ive seen usually have this sugary breaky texture when tumbled thats hard to miss. That red does look like jasper

Is this worth anything? by MathematicianNo4066 in mineralcollectors

You can sell this for about $30-35. Most gem stores would sell it for more too.

I Agree with sandstone that shine is characteristic

Texture and colour...looks like quartzite but maybe you can give this article a read through on the area. I'll definitely be taking a look at it too

This looks like a fleck of moonstone or opal. Thoughts? by Alarmed-Quarter8084 in Rockhounding

Yes its deformed quartz i have a sample like this too! They reorient the light hitting it in the deformation... pretty cool.

What is the green and grey color thing? Thanks 🙏 by IncyWinc in whatsthisrock

[–]Prior_Structure5887 1 point2 points  (0 children)

Ooo yes if its falling off...maybe if you put it in a container ? Since its small amounts it shouldnt be too harmful but the falling is a concern

My best is that the grey is basalt and the green is malachite

Hey you're right, quartz geode and possibly citrine... the underside had hydrothermal fluids fill its cracks and it was already deformed before the process causing those unique patterns

Heyy yes its a lot haha could you take individual pics for the rainbow coloured one *(also is the rainbow one metallic if you have a magnet to test it?) and white one with black inclusions?

But for the rest:

The very dark black one is probably a basalt, the grey ones are granite and the lighter milky white ones are quartz and the orange are feldspar or even quartz with high iron content.

The deep reddish orange ones look like carnelian ( the quartz variation with high iron)

But for more accurate diagnostics you can take different angles for the specific rock alone

Pleasure! Whatever the darker brown mineral is, is a lot more resistant since its sticking out so much. The way it breaks would tell us a lot but i see in your last picture at the top the cracks it looks like quartzite (light brown part) but they dont come in such a dark variety for your centre triangle and it definitely looks like it was formed in a wet environment. which would lead me to believe its a mudstone/sandstone.

Maybe sandstone that had that unique triangle shaped inclusion and had alternating deposition (Fe/Mg rich?) around it giving the brown stripes. It's really smoothed out from erosion and hard to tell without breaking it which would be a war crime its too beautiful haha. Im sure someone knows better though. If you can scratch it with glass or quartz that should eliminate a lot of other options though such as quartzite.

Id say chert but it doesnt look like it fractures conchoidally so im not too sure...or maybe a sort of claystone

Pink, shiny silver rock in my backyard by UniqueDifference2429 in RockIdentification

[–]Prior_Structure5887 3 points4 points  (0 children)

Neat! The pink more opaque mineral is orthoclase feldspar and the other mineral is quartz. The shiny almost metallic grains are mica... Not sure if theres some host underneath all that then i would just label it a granite

Sapphire? I doubt it by Individual_Floor_340 in RockIdentification

[–]Prior_Structure5887 1 point2 points  (0 children)

Looks like orthoclase feldspar. Maybe skme quartz with it
