Here are a few pictures of some amazing specimens of Goethite.
This first specimen is smaller than a dime. Enjoy!

QUOTE In the U.S., the best specimens are radiating crystal clusters from pegmatite pockets of the Florissant region of Colorado. I have some! QUOTE Crystal description- Small, black, shiny, equidimensional crystals rare. Commonly in slender flattened plates, velvety surfaces of needles, and occasionally in brilliant rosettes of radiating plates. Also fibrous-massive with reniform surfaces; compact or earthy, even vitreous in the type called Glaskopf. Compare with limonite (following). Golden needles included in quartz.

Another little black beauty.
No scrubbing involved when cleaning these specimens.

Thanks! No, Goethite is not related to rutile. You can find more information on Goethite in the link in my post above.
Yes, that is dino bone the Goethite is on...hehe Beautiful slab isnt it? -------------------- Education is the key to the future,

You can also check out our Colorado Goethite page. It also has some great information and reference links.
Here is another picture of a piece of Colorado Goethite that has not been cleaned all the way yet. Sure will be cool when the cleaning process is finished. This piece has a hole in its backside, (perfect crystal shape) showing where the Goethite formed onto the quartz crystal. Shame that sometimes the Goethite pops off the crystals. I'll post a picture of the backside soon. For fun I thought I would add this close up picture of some Goethite. Colorado's Goethite is the best in the USA. -------------------- Education is the key to the future,

Here is a picture of the backside of the Goethite pictured before the closeup photo.
Almost looks like a wee rusty mining spike stuck inside the Goethite crystals. -------------------- Education is the key to the future,

IIRC goethite is a secondary replacement mineral? Iron oxyhydroxide (FeO(OH)). -------------------- Today's socio-political climate is rock solid proof that Adam and Eve weren't prospectors.
If they were they'd have eaten the snake instead of the apple and we'd still be in heaven.... |

Its actually a primary hydrothermal mineral, in the diaspore group.
Formula: α-Fe 3+ O(OH) "Named For German poet, novelist, playwrighter, philosopher and geoscientist Johann Wolfgang von Goethe." -------------------- Education is the key to the future,

Here is a video of some of my recent Goethite finds. One of them has some Amethyst (Onegite) with it. The last large one has Hematite forming up through the middle.

Sweet specimens Mike! You have some really nice looking Goethite on your claim! Love the combos, especially the one you held up to the light.......Amethyst color showed right away. Very cool, never seen Amethyst with Goethite before....Excellent find! Shame the one Goethite broke, it had a great shape going on. You clean yours with a textile gun? That's how we clean ours and it seems to work really well.
Great example of how cool Colorado's Goethite is, thanks for sharing the video with us. -------------------- Education is the key to the future,
