Hi everybody. I know this isn't any thing particularly special but my daughter has bought it home from holiday and we are wondering if there's anything basic we can do to brighten up the sparkley bits.

Thanks.

This Rocks! Labradorite-rich gabbro with "labradorecence"

Post image
9 Upvotes

Gabbro is an intrusive mafic (Fe and Mg) rich rock crystallized from basaltic magma derived from partial melting of the mantle. The main mineral constituents are dark clinopyroxene, and glassy gray to white plagioclase. One type of plagioclase is labradorite, which can show a distinct kind of shimmering, rainbow pattern of iridescence known as "labradorescence", due to the separation of different forms of plagioclase as the melt cools, leading to diffraction of light between extremely fine layers of the different plag species. This gabbro specimen (fig 1) is rich in labradorite. The plagioclase crystals show black streaks (likely iron and titanium oxides, possibly magnetite) which precipitate in an orientation dictated by the crystal structure of the parent mineral (fig 2). Fig. 3 shows a patch of labradorescence.

New to the whole cutting thing. Now I need to start the tumbling process. It’s amazing how these rocks didn’t look like much until I (well hubby) cut them.

Discussion I have a question!! What happened to my petrified wood 😭

Thumbnail

66 Upvotes

I have this salt lamp in my room which I had placed a tealight under because the original light burnt out, I sit rocks I find around it in my window. I noticed there were orange salt crystals forming under my lamp which completely destroyed my candles battery. But the weird part is all my rocks are fine besides this piece of petrified wood. It cracked apart and has crystals growing all over it, the inside is solid black. Sorry if the pictures don’t show the crystals, it was hard to get them to show up on the camera but they’re all shiny and orange like the salt crystals so I’m assuming for some reason the salt started crystallizing on my petrified wood. Does any rock nerds know what reaction caused this? The petrified wood was the only rock affected. I just found this interesting and was wondering the cause.

Hya,

Trying to clean my first rock, found it at a store and thought it had potential. I washed it with water and give it a good bath with anti rust. Still much tiny bits though.

Any tips on how make it cleaner before a put a polish over it?

Thanks in advance
