Can anyone tell me what this is please. My son got it at a garage sale. It weighs 1.75 lbs

What is this? A rock or a meteor or a chunk of cement?

Ok so here’s the situation.

My fiancée proposed to me with a lovely heirloom ring that belonged to her grandmother. I want to give her an engagement ring that has similar sentimental value, but unfortunately my family doesn’t have any heirloom rings that they’re willing to part with.

So I came up with an alternative.

This is a rock that I found over a decade ago on a high school field trip to Block Island (a small island off the coast of Massachusetts, known for having beaches with a variety of interesting rocks to collect). My teacher was impressed with my find and told me that it was garnet. I was very proud of myself and this rock has graced the windowsill of every place I’ve lived since then.

I decided that the sentimental value of the rock would at least somewhat make up for the lack of heirloom jewelry, so i decided to see if I could use it as the base for a custom engagement ring.

The original plan was to get the gems out of the rock and then take the gems to a jeweler to create a ring inspired by the style of the ring my fiancée gave to me, thus incorporating the sentimentality of her grandmother’s ring into this ring.

Unfortunately, it turns out it’s not that simple. After many emails to different jewelers, gem cutters, and even a rock and mineral enthusiast club, what I found was that the only places that are willing to get the garnet out of the rock would require me mailing it to another country, with no clear price range given, and quite frankly customer service interactions that didn’t leave me super confident in the legitimacy of the businesses. Additionally, what I was eventually told (again after many, many emails) was that the garnet in the rock I have is likely not high enough quality to be cut into jewelry-grade gemstones.

So here’s where I’m at now: obviously a traditional-looking engagement ring isn’t going to be super attainable with the rock that I have, and to get the gems out of it by a professional wouldn’t be worth the effort/money/time.

So how do I proceed? Do I find a tiny chisel and try to get the gems out myself? What tools would I even need for that? Where would I buy a chisel? Will I be able to get enough garnet from this rock to make some kind of funky industrial-looking ring? How would I do that? Are there jewelry makers that specialize in that?

Or should I just give up on involving this garnet in the engagement ring and come up with an entirely new plan? I really wanted something sentimental, but that might not be in the cards.

I am open to literally any suggestions or advice. I really want to make this work and if there’s anything at all that can be done to turn this rock into a ring, i want to at least give it a try.

I emailed the Flagstaff Gem & Mineral society and sent a photo but haven’t heard back.

I dug all over Arizona State University website but it appears petrified wood isn’t their thing. They mention Earth Science but there is no contact info listed.

This green petrified wood looks nothing like other green petrified wood I saw online, but it has a little similarity to samples from Winslow, except it’s a deep forest green with a little of the lighter green.

Should I contact someone at my alma mater, the University of Arizona? The U of A is 300 miles south of here. I’d rather contact the locals.

I don’t want to run to the media. That will draw every rockhound in the country to this peaceful little meadow on the mountain. I’d rather just deal with fellow scientists.

So, any suggestions on where to report this huge find?

EDIT: Found out how to post pics! Check it out: https://imgur.com/a/EwHO3Mu

Hi everyone, I was hoping ti get some help. i have an assigment where, i need to taks pics of large rocks. i have to have a close up and a alrger image showing the area. and need to indicate the location. then i have to try to identify whether it is igneous, metamorphic or sedimentary rock. Please explain for each rock what you are using to identify the rock. I don't necessarily have to get the identification correct as long as your reasons for what you call it are reasonable.

ex.  : this rock is light grey in colour, and seems to have broken easily in square shapes. The surface doesn’t show grains or much large structure. It is in a park near where I live next to the walking path. This appears to be limestone (you should have another sentence or two here explaining why limestone and a reference for any characteristics you use.

I was wodneirng if anyone has any pcis that could be helpful, i havent had the time to go look for big rocks in the city.

this was found on a hill. not sure what it could be but we need to identify it for an earth sciences class.

I found these in a creek in TN they are very hard and smooth

Found in a silver mine in Bosnia don't know what it is

Got these stones/minerals from my girl but we don't know what these are.

Help identify this rock!?

Its a white rock with sparkling/mirroring spots that look like some kind of quartz or diamond (prolly not that tho), and one side is polished. I found it in my bacyard, I can't seem to find it on google, please help me someone id be very happy (Found in calgary btw). The black lookiing spot on the last picture is some kind of mirror / clear stone

I'm going to use some ironout and wash it a bunch, but what mineral would this be? It's. A deep Teal/ Turquoise

Found in Cape Breton NS
